Would love to see more Combat Robot content on your channel! Maybe a fusion 360 robot design tutorial. Or a video series showing the process from design, construction, to competing with the robot.
Watched the whole vid anyway, but love you adding time stamps! Wish more people would. Have you tried printing parts with glass fibre reinforced filament? Or making your own wheels with flexible filament. Great video mate!
Since many 3D printed parts have lots of little voids you could try forcing a filling resin into them in a pressure or vacuum tank. One to try is a heat cured resin called Cactus Juice. It's made for use with wood to stabilize it, used a lot by pen turners. Cures at 200F
Angus, I just came across your old channel while researching for builing a bot, I got some really good info but I'd love to see more Combat Robot content from you on here, maybe its time to make a ant weight. :)
Love the robotwars video. As a newcomer to 3D printing (mainly due to your videos) I am only interested in functional parts so this was very interesting and informative. Keep up the great work and would love to see more tutorials on Fusion 360, etc.
Great video! Most of the technical stuff went right over my head but your love of engineering dedication to explaining it comes thru loud and clear. It reminded me of my programming days back in the 90s when I would come up with some very obscure but very elegant programatic soltution consisting of multiple layered, nested if-then statements, modal windows, variable array components, etc. that I just could NOT share with virtually anyone in my life. It seems like RUclips fills that void 4 u. Cheers!
Great!! Thank's for all the information and components list. I really like that kind of robot competition but unfortunetly there are not take place in my country ! Enjoy a lot with your Vanguard mate! I will stay tuned for future updates of your results!
I've watched this video multiple times. I build robots as a hobby and I just recently purchased a 3D printer. I'm dying to learn to make robot parts. I'm starting out with a Maker Coin which is going reasonably well. Thanks for enabling our creativity!
A pneumatic flipper will present a problem, but if the robot is fast enough to out-maneuver it, and has a self-righting mechanism, it won't be as much of a problem.
If anyone can make an awesome mostly 3D printed ant weight it's you! GREAT video, would love to see your adventures into CNC as well! Very well put together video!
This video brought back fond memories of the 2001 Battlebot competition. I entered a middleweight named GoatHammer, and qualifying was pretty hard, I had last minute weight problems...lost my first fight, but it was fun for a week on Treasure island in San Francisco. I just ordered my first 3D printer, wish I had something like that 19 years ago...thanks for the informative videos, you give honest valuable advice...Cheers!
Glad to see an in depth video of your experience. I would love to see you do more types of making! Cnc and your welds look pretty good too. I love the Ant weight robots, you should definitely make one or two! It would be fun to watch the design on fusion too.
Really like project videos from you and others. They show real-world problem solving and multiple making techniques that you just don't get with simple 3d printing videos. Tutorials and mechanical history videos are also good. One of the things I like about your channel is you understand this, and you try to avoid doing the same common print and review videos so many others do. You need to do reviews to support your channel, because of the relationships you need with those in the business and that lots of people do need advice on what to buy. But you always try to do testing and reviews with something different from others, either by using your more-rigorous test items, or by doing project items as part of your testing. Good job. And I'd definitely love to see more making outside of 3d printing, such as CNC and laser work. Or even off-the-shelf mechanical stuff, if you end up with a cool end product.
Great to see Strange Young Man in the video! I was surprised how long his head lasted, it was only PLA, printed with thin walls and almost no infill. As for ants, I've started printing my shells in TPU with great results. Ant weight weapons aren't strong enough to rip TPU so it just flexes out of the way. I'm going to put up a video on my experiments soon
Strange Young Man was the definite crowd favourite!!! Keen to hear more about the TPU, maybe it could even be dual extruded with a harder inner frame... hmm
Yeah! now I just need to get a bit more power in the lifter to make him more competitive but he'll definitely be back next year The TPU video is being rendered now and should be up monday night. It'd be great to see you take a swing at it, dual extrusion would make a world of difference.
Would love to see a cnc series, I got into 3d printing as a self taught path into cnc and would love to see one of my favorite 3d printing channels follow the same evolution I am attempting.
Angus, This was an awesome overview of your practical application of 3D and CAD, as well as engineering and design challenges. In short, too interesting to not continue! Please do more like this. Perhaps the upgrade of this robot is most appealing.
Nice TIG welds, machining, and craftsmanship all around! It's no surprise you did so well in the comp. As you posted pics, I thought to myself the wire management could use some attention, then you mentioned a plug coming undone. Wire management is key in these types of high-abuse builds. You can 3d print some channel to protect and route the wires.
I've successfully used pla for motor mounts and wing mounts for rc aircraft. It holds up pretty well in those applications, because at cruise a plane will only have lift equivalent to its weight, and even a 5g maneuver would only be 10lbs on a 2lb plane.
dang it, you've made me want to learn how to do this! I even went a found an organization that does these locally...but I would still have to learn how to do literally everything from scratch
Thankgoodness i was beginning to think i was surrounded by kids printing toys, toy guns, helmets, and cartoon statues. Useful or forget it. Robots demonstrate usefulness and practical applications.
I don't think it's actually possible for a subscriber base full of nerds to get upset at a robot fighting video. But in all seriousness this was awesome. Would love to see occasional updates on your bot as well as some CNC material since that seems to be another growing hobby.
I'd love to see more Combat robot videos, your videos are great and I really like the ideas behind Vanguard. I had a battle bots class 4 years ago, I was in GR.9, it was very low budget, drill motors and armor made of sheet aluminum but still a ton of fun.
When we were competing in school, there was a robot similar to your design, except the spinning weapon was in the center of the bot from an aerial view. they added slightly larger ramps fore and aft of the weapon to act as a runway. That heckin robot took ours (15 Lb Class) and launched it straight up so hard it hit the enclosure ceiling (maybe 3 or 3.5 meters up). My point is that you got a pretty sweet design, and I would love to see more robot combat in the future. Cheers
That reminds me, At that same comp there was a dude with a robot that was 80% 3d printed ABS (everything but the motor mounts and the weapons, even the outer casing was 1.5" ABS all around). It was a basic wedge with a steel chain mace (flail?) on the back. That one was fiesty as heck, but ultimately lost because he was too light. It never actually quit working (TANK MODE FTW), it's just that the judges awarded a ton of points to his competitors cuz he was getting tossed around like a rag doll. That and he never had to compete against the team that curb stomped our bot lol.
Awsome video Angus !! It would be interesting to see your take on smaller fully 3D printed "combat robot" and more CNC on the channel is a realy good thing in my opinion. Keep up the good work
Definitely interested in more CNC content! I think the combo is great, as you can print everything from circuit boards, metal cases, to whatever other metal part your project might need, then make all kinds of custom plastic parts and cases with the 3D printer.
Id love to see a mostly 3d printed robot competition. bots would have to have a higher percentage of 3d printed parts to metal, i think that would inspire a lot more innovation and creativity.
Yes for CNC AND yes for robots! Include durability tests for PLA/ABS/NYLON/OTHER filaments in robot use. Also how about filaments that handle gasolie/diesel? Hight temp resistance filaments? Nice vid! :)
Do I like technical details?! Dam right I do :-) Personally, I don't use time-stamps on any of your vids, I enjoy every second. But nice of you to include them for those that do. Awesome video Angus, you did real well in the wars too. Fantastic! I'd love to see some 'how to's' with more detail, do you plan to do any?
Might I suggest reversing the orientation on the main weapon? Having it rotate top-forwards instead of top-backwards would give the weapon more bite than a simple flipping wheel.
The intention is to force the other robot upwards with the opposite reaction being transferred into the floor, if it span down it would send my robot flying :)
That was very interesting, and I would love to see any kinds of fabrication on your channel. Mixing different fabrication methods as needed to get the desired results is just good engineering!
I realize this is 3 months late, but man I would to see you build one of those tiny robots. I've always wanted to build a combat robot, but it has been just not feasible due to budget constraints and other factors. A mini bot is the one thing that seems like anyone with a 3D printer and the know-how can make, so seeing you build one/getting a guide for one would be amazing.
If you use a deans connector for your safety disconnect, it will not come out unless you want it to. I enjoyed hearing the details of your fights. As a newcomer to 3D printing, I have found your vlogs to be the most informative and down-to-earth. Keep up the good work!
Looking at the way the gear failed, the solid infill pattern only provided strength on every other layer. Next time you should increase the number of perimeters until they completely fill up the teeth so you get maximum planar tensile strength for each tooth without having to rely on intra-layer bonding. Looking forward to more heavy-mechanical tests of 3d printed parts!
Hey Angus, it's cool to see you using polycarb as it's my favorite material to print with, half my Robo3d is polycarbonate now! For your gears and other meshing parts, you might want to check out Igus' l180, it's designed for printing bearings and is a self-lubricating, abrasion-resistant filament. I got a sample from them recently and have printed a couple of linear bearings and I'm astounded at how well they work!
CNC cut your gears out of something even tougher, like metal or Tufnell. Ideally Tufnell for the big gear and polished steel for the small ones. You could probably buy the small gears so cheaply it's not worth making them.
Funfact: nylon is durable to the point where the puffing billy railway replaced a full set of bearings on one of its locomotives as a test and the results were less wear, friction and better heat dissipation than the original metal bearings. Keeping in mind these locos are over 100 years old.
Now I wanna make a robot!! Also hell yes on more CNC stuff also you could also possibly print your own drive belts with flexible filament and you totally have to make an antweight robot they are adorable!
a league of entirely printed combat bots would be great because there would be actual structural damage. those metal bots are too tough, all that weapons still dont do much damage. plus, its easy to manufacture spares. nice vid :)
If it were so, basically every fight you lose would mean your bot has been smashed into dust or disintegrated, you basically have to rebuild it every time you lose.
Great video Angus. really enjoyed it. Maybe you could make a video to explain the finer points of getting your settings right for those more difficult 3d printing materials.
I love the spinning disc design on combat robots, it's just as proven and effective as the flipper, bit to me the horizontal disc seems more effective then the vertical, your design is absolute beast and sure that wirh a heavier weapon and high rpm (maybe a stronger motor it would make a ton of damage, I'd love to build one myself but the scene here died out in the late 90s sadly, and I would have gone with a similar design to yours but with a horizontal spinning disc insted 😁 great video as always would love to see more like this too😊
Thanks for trying 3d printing in combat robotics. Been wondering if it was usable since I asked Mark Setrakian about it 3 years ago at a RoboGames event; at the time he said printing wasn't yet viable for combat. However, he did bring a really cool 3d printed hand that held and rotated a beach ball sized globe on five fingers. If you can spare the weight and hide the heads, I'd recommend using double nutted bolts instead of screws. Also good call on the belt for the main weapon, seen a lot of chains and gears break from hard impacts. Good luck with your next build!
@ 1:10 funny to see the effect the centrifugal force (and gyroscopic effect) of the weapon has on that robot, it really didn't want to make turns to the left.
Some of the FRC teams that I work with use those same Banebots Gearboxes. You also might want to look at using something like a Vex Versaplanetary gearbox if you want something that you can easily change the gear ratios of. Versaplanetaries are absolute tanks of gearboxes. One of the teams that I worked with ran one with a 300:1 gear ratio to lift our 120 pound robot onto a platform 18 inches off of the ground.
More cnc please. I thinking in doing a home made one for hobbies. At first I didn't tough I was gonna like your vids but can't stop watching them now 😂😂
That's a heavy duty little tank you've built Angus (hope I've got your name right). You should take up the extra weight trying to make it stronger on the inside, as a lot of these robots tend to break there mostly. Then to top up the weight you could beef up the flywheel spinner weapon.
Thanks Angus. I really enjoyed watching this. Maybe you could print a skirt that would snap fit around the base and close the gap between the base and the floor. It's not like you need a great deal of clearance. If you come out around the bottom you could give yourself a decent ramp for the victim to slide up into the spinning wheel of death:)
Threaded insert master race! But in the future, when using those cheap straight-knurled inserts I always insert them on the rod side. So instead of having a through-hole on that mounting block, there should be a lip on the outside that the insert can be pulled tightly against when you tighten the grub screw. It's a lot safer, I think. Heat insertion like you did there should only really be done with better-quality inserts that have helical threads to actually grab the plastic.
Agreed. Inserts with straight splines are designed to be press-fit from the opposite side. Inserts with a knurled finished are designed to be heat-staked.
You could use 3d print of that pinion gear as a cast, to melt the hardox metal into that shape as well as you can and cnc that almost complete shape quicker than out of a block.
Maybe printing a prototype with PLA or ABS and see where it fails in test drives could give you an idea of possible weakspots in your designs that you should improve/reinforce, before you print the parts in the more expensive advanced durable plastics for the competition... And i'd love to see more about combat robots, even if it is just about antweight bots.
You can make molds and cast with resin - that way you'll get much stronger gears and such. You could do the same with metal if you have the skills, but it's not difficult to melt aliminium
You should definitely start building some plastic ant bots. That way you can at least do some troubleshooting on a proof of concept before throwing an untested, full scale bot straight into the arena.
Two things: 1) Before nylon, I suggest you try some ColorFabb nGen filament (hopefully "for-review" - I'm sure they will send you some ;) ); IMO it is easier to print than nylon, and strength-and-"flex"-wise I bet is (again IMO, of course) better for a combat robot. And, 2) This video was awesome! :D I'm in 'Murica, where "battlebots" was A Big Thing back in the late 90's, at which time a bunch of my friends and I spent countless hours discussing exactly how we could/should go about abusing the Battlebot rules to create something that would be absolutely destructive on the battlefield. Granted, at the time the sport was young and rules like "no electrical weapons" did not yet exist - heh heh heh - so that gave us a broader spectrum of ideas to pull from, but ultimately we were all Lazy Gamers With No Mechanical Skills so nothing came from it anyway. :-/ In any case, this vid brought back really good memories and I'm totally stoked that you made it. Keep up the awesome work, my virtual friend! :D
Would love to see more Combat Robot content on your channel! Maybe a fusion 360 robot design tutorial. Or a video series showing the process from design, construction, to competing with the robot.
baker crz also explanation on electronic would be nice.
Robert Cowan has a good channel where he does a lot of stuff with combat robots.
me 2
yeah and make it deadly with graphene blades and real machine guns
@@harrygregory6227 Yeah LOL
Well documented! Great to see how well the printed parts held up! oh- and yes- more CNC!!!
Thanks man! Will I be catching up with you in NYC?
Unfortunately I have to sit NYC out. Would have been great to see you again and meet Lady Muse!
Lame! Ah well, it won't be out last trip stateside.
PLEASE DO MORE CNC
His channel is mostly about cnc...
So maybe a Mostly Printed CNC? www.vicious1.com/
Yes please
pls do!
YES WE NEED MORE OF THIS
Please do more about robot wars, and make it a series! I really love watching this!
Watched the whole vid anyway, but love you adding time stamps! Wish more people would.
Have you tried printing parts with glass fibre reinforced filament? Or making your own wheels with flexible filament.
Great video mate!
I have some glass reinforced PP filament that I really want to find time to test out, and yeah even printing the wheels could be pretty neat!
Maker's Muse awesome looking forward to watching it when it comes out!
Since many 3D printed parts have lots of little voids you could try forcing a filling resin into them in a pressure or vacuum tank. One to try is a heat cured resin called Cactus Juice. It's made for use with wood to stabilize it, used a lot by pen turners. Cures at 200F
Gregg Eshelman interesting! Might look into this.
This is awesome! I hope you do more videos on robotics and CNC!
Ditto!! More practical design vids, please!!
I agree iwould Love to see more videos of robots and cnc
agree
starfilmsanimation /
Definitely!
Please make an ant weight robot! that would be so cool!
Yeah, I would love STL's and a part list so I can make a couple for at home battles.
The botbitz website has STLs and instructions (and parts for sale) for a little lifter ant.
Do It!
After 5 years, he fulfilled your request!
Would love to see a Maker's Muse ant weight!!
I love how your passion is so obvious! It's contagious!
Angus, I just came across your old channel while researching for builing a bot, I got some really good info but I'd love to see more Combat Robot content from you on here, maybe its time to make a ant weight. :)
Heh I would love to build something again! Yeah, maybe an ant :)
Love the robotwars video. As a newcomer to 3D printing (mainly due to your videos) I am only interested in functional parts so this was very interesting and informative. Keep up the great work and would love to see more tutorials on Fusion 360, etc.
Great video! Most of the technical stuff went right over my head but your love of engineering dedication to explaining it comes thru loud and clear.
It reminded me of my programming days back in the 90s when I would come up with some very obscure but very elegant programatic soltution consisting of multiple layered, nested if-then statements, modal windows, variable array components, etc. that I just could NOT share with virtually anyone in my life. It seems like RUclips fills that void 4 u. Cheers!
Do more robot battle stuff please!!! I am really interested in it
Nathan Becker make a mostly 3d printed and cnc minibot
Great!! Thank's for all the information and components list. I really like that kind of robot competition but unfortunetly there are not take place in my country ! Enjoy a lot with your Vanguard mate! I will stay tuned for future updates of your results!
I'd absolutely LOVE some CNC videos on your channel :)
Well, it's been a while since I haven't appreciated one of your video that much! This was very cool stuff, and I would love to see more CNC of course!
Thanks! It took tonnes of effort but was well worth it. Definitely keen to start some CNC now of my own.
Yes, more CNC videos! The light mini not competition would be interesting too.
I've watched this video multiple times. I build robots as a hobby and I just recently purchased a 3D printer. I'm dying to learn to make robot parts. I'm starting out with a Maker Coin which is going reasonably well. Thanks for enabling our creativity!
How to win a robot competition. Build a wedge with the most powerful motor put all the weight into armor. Be prepared to be called boring.
Alan Wong I had the same idea lol.
until you come agianst a pneumatic flipper
A pneumatic flipper will present a problem, but if the robot is fast enough to out-maneuver it, and has a self-righting mechanism, it won't be as much of a problem.
What about a robot that pulls a reverse hovercraft and gives the arena floor the succ to be unflippable.
Unless you drift around like Gary Gin
This was my favorite video from you so far. I liked seeing the creative ways you used the printed parts and WHY they did or didn't work.
If anyone can make an awesome mostly 3D printed ant weight it's you! GREAT video, would love to see your adventures into CNC as well! Very well put together video!
You have a gift Angus! Love seeing how you approach technical workarounds and design. Would love to meet you someday brother.
This video brought back fond memories of the 2001 Battlebot competition.

I can't take credit for the welds! Definitely had to leverage a lot of help as I no longer have a 'dirty' workshop. Something I'm keen to change soon.
I think a Tig welder/plasma cutter would be your new favorite toy.
More CNC stuff would be amazing. Also this earned a new sub!
From Who?
JK
Great video Angus. Glad to see some 3d printed parts making it into the robots and these kind of videos in general. Keep it up!
LOVE the 3d printing durable robot part theme. I want to make the most durable 3d parts possible! Great work
Really like project videos from you and others. They show real-world problem solving and multiple making techniques that you just don't get with simple 3d printing videos.

But in all seriousness this was awesome. Would love to see occasional updates on your bot as well as some CNC material since that seems to be another growing hobby.
In regards to the gears printed in PC-MAX, did you anneal the gears in the oven as recommended by Polymaker?
I'd love to see more Combat robot videos, your videos are great and I really like the ideas behind Vanguard. I had a battle bots class 4 years ago, I was in GR.9, it was very low budget, drill motors and armor made of sheet aluminum but still a ton of fun.
Frags flys around that arena like a absolute mad man holy shit. that thing is fast and stops on a dime
When we were competing in school, there was a robot similar to your design, except the spinning weapon was in the center of the bot from an aerial view. they added slightly larger ramps fore and aft of the weapon to act as a runway.

Make an update video for 2020 robot you have with parts description like this video.....it helps alot
Thankyou
Would love to see the full robot making process and cnc :')
Great vid Angus! Love to see more in this style, applying 3d printing solutions to real world challenges.
Definitely interested in more CNC content! I think the combo is great, as you can print everything from circuit boards, metal cases, to whatever other metal part your project might need, then make all kinds of custom plastic parts and cases with the 3D printer.

A completely 3D printed robot would be super cool!
Would be so interested in a full CAD live stream on this

Great video Angus. really enjoyed it. Maybe you could make a video to explain the finer points of getting your settings right for those more difficult 3d printing materials.
I love the spinning disc design on combat robots, it's just as proven and effective as the flipper, bit to me the horizontal disc seems more effective then the vertical, your design is absolute beast and sure that wirh a heavier weapon and high rpm (maybe a stronger motor it would make a ton of damage, I'd love to build one myself but the scene here died out in the late 90s sadly, and I would have gone with a similar design to yours but with a horizontal spinning disc insted 😁 great video as always would love to see more like this too😊
Can you please set up a P.O box so we can send you stuff
Dammit man, your videos are too good. I get depressed when they end...
Show "Lost PLA" casting !!! , Turn those 3D printed parts into aluminum :-) (Don't forget to add 3% for shrinkage)
Thanks for trying 3d printing in combat robotics. Been wondering if it was usable since I asked Mark Setrakian about it 3 years ago at a RoboGames event; at the time he said printing wasn't yet viable for combat. However, he did bring a really cool 3d printed hand that held and rotated a beach ball sized globe on five fingers.
If you can spare the weight and hide the heads, I'd recommend using double nutted bolts instead of screws. Also good call on the belt for the main weapon, seen a lot of chains and gears break from hard impacts. Good luck with your next build!
@ 1:10 funny to see the effect the centrifugal force (and gyroscopic effect) of the weapon has on that robot, it really didn't want to make turns to the left.
Some of the FRC teams that I work with use those same Banebots Gearboxes. You also might want to look at using something like a Vex Versaplanetary gearbox if you want something that you can easily change the gear ratios of. Versaplanetaries are absolute tanks of gearboxes. One of the teams that I worked with ran one with a 300:1 gear ratio to lift our 120 pound robot onto a platform 18 inches off of the ground.
It'd be great to see a video on printing nylon. I'm having a hell of a time with it, I just can't get past the warping.
Nicely done, and yes I would like to see CNC stuff and the mini robot making.
This is awesome.. the story behind the robowar machine, very cool.
Excellent material selections. We definitely want more CNC, I'm personally starting classes this fall for machining.
More cnc please. I thinking in doing a home made one for hobbies. At first I didn't tough I was gonna like your vids but can't stop watching them now 😂😂
That's a heavy duty little tank you've built Angus (hope I've got your name right). You should take up the extra weight trying to make it stronger on the inside, as a lot of these robots tend to break there mostly. Then to top up the weight you could beef up the flywheel spinner weapon.
Thanks Angus. I really enjoyed watching this. Maybe you could print a skirt that would snap fit around the base and close the gap between the base and the floor. It's not like you need a great deal of clearance. If you come out around the bottom you could give yourself a decent ramp for the victim to slide up into the spinning wheel of death:)
Threaded insert master race! But in the future, when using those cheap straight-knurled inserts I always insert them on the rod side. So instead of having a through-hole on that mounting block, there should be a lip on the outside that the insert can be pulled tightly against when you tighten the grub screw. It's a lot safer, I think. Heat insertion like you did there should only really be done with better-quality inserts that have helical threads to actually grab the plastic.
Agreed. Inserts with straight splines are designed to be press-fit from the opposite side. Inserts with a knurled finished are designed to be heat-staked.
You could use 3d print of that pinion gear as a cast, to melt the hardox metal into that shape as well as you can and cnc that almost complete shape quicker than out of a block.
I really enjoyed this video. Thanks for making it. I'm interested in more robot and CNC content.
Great work Angus, definitely keen to see some CNC stuff on the channel, and also would love to see a 3d printed mini battle bot :)
Maybe printing a prototype with PLA or ABS and see where it fails in test drives could give you an idea of possible weakspots in your designs that you should improve/reinforce, before you print the parts in the more expensive advanced durable plastics for the competition... And i'd love to see more about combat robots, even if it is just about antweight bots.
You can make molds and cast with resin - that way you'll get much stronger gears and such. You could do the same with metal if you have the skills, but it's not difficult to melt aliminium
You should definitely start building some plastic ant bots. That way you can at least do some troubleshooting on a proof of concept before throwing an untested, full scale bot straight into the arena.
I really enjoyed seeing this and your explanations for everything. A smart man is you. 😉👍💥⚙️🛠
Takes me back to the day I made a robot for robot wars. Things would have been a LOT different if I had a 3D Printer.
Yes! Please do a CNC machine from 3d printer parts or something similar. Love the channel. Keep making the videos and I will keep watching them. 👍
Great video, love to see more Robot and CNC videos :)
I subscribed in anticipation for more CNC!
CNC - Yes! Make an MPCNC - best of both worlds. I made one and am very happy with it.
your perspective on CNC would be most interesting, Thank you for what you do
Awesome video! I love real world use application of 3D printing.
Two things:
1) Before nylon, I suggest you try some ColorFabb nGen filament (hopefully "for-review" - I'm sure they will send you some ;) ); IMO it is easier to print than nylon, and strength-and-"flex"-wise I bet is (again IMO, of course) better for a combat robot.
And,
2) This video was awesome! :D I'm in 'Murica, where "battlebots" was A Big Thing back in the late 90's, at which time a bunch of my friends and I spent countless hours discussing exactly how we could/should go about abusing the Battlebot rules to create something that would be absolutely destructive on the battlefield. Granted, at the time the sport was young and rules like "no electrical weapons" did not yet exist - heh heh heh - so that gave us a broader spectrum of ideas to pull from, but ultimately we were all Lazy Gamers With No Mechanical Skills so nothing came from it anyway. :-/
In any case, this vid brought back really good memories and I'm totally stoked that you made it. Keep up the awesome work, my virtual friend! :D
