RC Tracked Vehicle #3 - Giant Tracked Platform
HTML-код
- Опубликовано: 5 янв 2014
- This is my home made RC tracked vehicle that I built myself. It is using two AME wiper motors, a Sabertooth 2x25 motor controller, a 4-channel RC radio, and a 12V 7Ah SLA battery. The tracks are made with bike tire tread screwed on to V-Belts. This was all hand made at school with no instructions, kits, or tutorial guidelines/help. More videos will be coming soon as I continue adding features to this platform. Please leave a like =P

You know I watched this video 6 years ago. Ended up building 3 tracked rovers like this one cause it looked fun to make. Well that turned into 3 rc lawn mowers and 6 gps guided drones. And 3 1/5 scale trucks lol. Great video!
That's amazing! And thanks!
Thank you for such a detailed video mate,excellent work.
+Phil G Thank you! :)
Great video was looking for a track build solution, this is exellent...
Wow thats nice, thanks for sharing
+ifell3 thank you!
Nice job!
Very impressive.
Great video man and one super cool vehicle keep up the great work.
Thanks!
Enderman LP You're welcome
Good job, mate.
Thank you :)
It looks very nice!
How long did it take to build?
I like that the measurements are imperial and the weight is metric.
Excellent example of building a project. Good progress pictures and great video of machine operation,
Thanks for the ideas.
Thanks! :D
THANKS BRO ,, THIS WOULD BE MY MECHANICAL ENGINEERING
+Nicole Taylor the pulleys are 8" diameter on the outside with a 3/4" bore
and those "diamond things" are mounted ball bearings which I bought from the robot marketplace www.robotcombat.com/store.html
Great build. Thanks for the ideas and tips. I like your tread design. Gow has it held up??
+badandy122376 Thank you :) I'm glad you could get inspiration from this! The tread design is good, but it doesnt work too well on such a large vehicle. The v belts are just too flexible, and large amounts of traction (such as pavement or concrete) makes it derail. If you watch my Tracked Vehicle version 4 video I have come up with a new design that uses triplex chain instead of v belts which should be much better for a vehicle this size. When I have money i plan to build it, and see if it works as i expect it to. For now, don't use this v belt system for vehicles over 2 feet long, unless you only pan to run on smooth tiles or a gym floor :)
Wow thats such a long time
Did Mr . Inglis help you building it?
looks beautifull indeed! do you think it can be converted in to a lawnmover?
+Roman Choi
no, he just helped with some of cutting with the band saw, I did the rest myself :)
Cool !
Please show us test run outside .
Good job! A few questions. Have you done any load tests, as in how much of a load will it carry? I presume the only 'traction' on the front and rear wheels is made by keeping the distance of the front and rear wheels 'tight'? Have you experienced any 'slippage' when climbing things? Do you intend to use a toothed v-belt with the sprocket change? That's the only thing I can think of to make it work, but then you appear to know more about it than me! Keep auto salvage yards in mind when looking for parts, usually just a few bucks if you pull the part yourself. As I recall, the timing chain on the front of most older motors have two sprockets (and the chain in older, rubber in newer)on them. You have to bring your own tools to those places. Otherwise you pay more but the parts are already pulled. The reason for my questions is this: I am no longer able to crawl around my crawlspace to do any work. The crawlspace is leveled sand covered by insulation, held in place I think by stakes (I didn't do all that, I used to have to crawl around in the sand). I need the ability to sit on something, tracks or wheels, to get around down there (it's actually rather clean for a crawlspace). Obviously I would have to have lights, or conversely I could install lights in the crawlspace and not have them on the vehicle. That's all I can think of right now, again, good job. I'll be looking forward to your improvements.
+Paul W Thanks :) I have sat on top of the vehicle and it moves me forward and back just fine, the only issue is turning because there is so much traction the motors aren't powerful enough and they stall. The next version of tracked vehicle I build will use Banebots CIM motors and gearboxes, which I have calculated to have approximately 5 times more torque when geared 36:1 You can find more info on those motors here: ruclips.net/video/ZpHk5KLS0w4/видео.html The motors are more expensive (the gearbox is the expensive part) but you can choose how much speed:torque you need based on the Banebots gearboxes available of which there are lots of options. There are some files linked in the video description with a document I made calculating all the speeds and torques of all the gear ratios
o trabalho ficou muito bom.
hi i know your video came up in 2014 but any chance you can list the parts you used and where you got them from? Im looking to do something similar and I would like to know where to get the bearings for the wheel from? And the other parts. thanks Ah I think i found it in the comments below
Hey.. that was very powerful...... can u provide the link or any description about the motors from where u got that!!!..!!plzzz
Thanks for the video. Where did you purchase wheels/assembly and rubber tracks?
parabens otimo projerto proficional
cool!
Какой ток потребляет когда просто едет прямо?
Well done! How do you tension the tracks? How about a blade for snow?
solarsynapse thanks :) the mounted bearings at the front can move forward and back a little before tightening them with bolts
Good power, where you got the engines?
wonderful... i am doing one myself... the prototype worked beautifully with a wood platform. i am now stuck for the aluminum frame design. just don't know how to get that designed. :-)
Nice! Look up local metal shops, and try to design something using C channels or square/rectangle bars, those are easy to work with. Then all you need is a flat piece for top and bottom.
love the idea :Derailing concrete surface? would it help if 1. Keep the tyre intact so the sides keep it on track ? Why did you cut them off 2. some kind of chassis tensioner system
The sidewalls of a bike tire are very stiff, they will not streth because they have wires inside to keep their shape. This means you would not be able to stretch it out in the straight sections of the tracks. That's why they were cut off.
Real nice build man! I think you may have came up with the rubber track solution i need for my project lol!
Rich Morgenstein Thanks! :)
Enderman LP Just wondering one other thing! What did you end up using it for? Like any cool project it was used for or just to do what you did? Was looking for a part 2 lol!!!
Rich Morgenstein It was mostly a building project, but I did put a wireless camera on it and drive it around for fun. I'm currently in the process of designing the 4th version of this tracked vehicle, improving on areas from things I learnt during building. Its mostly for the experience and knowledge :)
Enderman LP I built pretty much the same item a while back but used a different track! I had butt hinges bolted end to end the whole track with a belt screwed as you did down all the center mounting holes of butt hinges. Works well but slips to much for my project. See mine has 3 5inch spinning blades as well under it to cut the law!!! lol all gps/optical flow driven apm unit to cut the yard :-) rubber tracks though wonderful idea of design for them. cheaper" as well. My worm gear drive only goes 80rpm anyhow out so these should hold up well under the slow conditions! Just curious if you don't mind you used 36 inch tire? How did you get a belt to match it? it's 35 3/4 inside a 36 inch tire and 36 OD of it?Stretch it?
Rich Morgenstein I used a 72" v belt and a 26" bike tire
There was extra bike tire length so its actually cut, but all the tension is on the vbelt, the tire is just for traction.
can you mention the inside diameter of the pulleys and the the name or types of diamond shaped devices used on the non motorized wheels.
Have you done any tests on rough terrain? And have you considered adding a suspension system (ideally independent suspension for each wheel) for better performance on rough terrain?
I used it on grass, but no I haven't though of adding a suspension system. That would be a lot more complicated, maybe for another project. I was trying to copy the military-style tracked robots, which have no suspension.
+Enderman LP Yea, I haven't really seen tracked vehicles of this size with any kind of suspension, either. I guess it depends on the speeds you're operating at and whether you need extra stability during movement that can't be provided by gyro stabilized gimbal or some other means.
Btw, if you're interested in military robots, you should look into the MCWL IROC challenge. I know some people entering it this year that could definitely use a platform like your V4 to build their autonomy systems on.
Cool, thanks :)
Can I use 12v 300 rpm DC gear motor?
Nice, I like the features this platform has. Do you sell them. I have a use for them. Let me know what the cost is. Thanks
+billie19842007 The parts aren't cheap and it would cost several hundred dollars to ship...so the thing would cost over $2k. Some companies like superdroidrobots or inspector bots make similar ones (a bit smaller) so maybe look into those instead. They also don't have their tracks derail on grass/concrete like mine does. I'm planning to build a 4th version of this vehicle which will hopefully not have that problem
1 ft tall without wheels?
very good idea.
The robot can to go upstairs?
Yes :)

Did you finish anything like this? Got a drawing or pics?
Hey, I was wondering where you purchased your 8" pulley wheels? I've been looking for them cheap, but maybe I will just have to spend the money. Thanks so much.
Got them at canadian tire for less than $20 each
@@EndermanEngineering Thanks so much! Few other questions. Did you have to cut a bike tire for your treads and what size bike tire tread did you buy? What did you use to connect your flange mounts to the wheels? Did you use a gearbox? If so where did you get your hex converter? Sorry to ask so many questions, your project is awesome and I am trying to make a rendition of it for my physics class. Thanks for your help.
@@georgegrune The bike tire was 26" size I think. The flange mounts hold 3/4" pipe which goes into the wheels. The AME motors already had gearboxes on them.
Hello, where did you get the aluminum wheels from?
Hi i'm planning on making one of my own but i just need some tutorial video's on how to build them that i can sea a little how its all done if you would know any video's/site's that can give that info that would be awesome i'm just struggeling with a couple small thing i'm a aircraft/drone builden and this would be a new part in the rc hobby hope you can help me out
thanks in advanced
www.societyofrobots.com/robotforum/index.php is a great place to start :)
could you explain your charging mechanism please? thanks!
+KurtleTheTurtle there is an IEC14 socket on the robot, which you can use any regular PC power cable to plug into the wall. The socket is wires to a switch (from a power bar) which then goes to another wire that pugs into the charger. The charger remains inside the robot for portability, and when the battery needs to charge you can plug the robot into the wall and the battery into the charger inside the robot and flip the switch. This could be improved by actually wiring both the charger and the motor controller into one switch, so that you can select whether you want the battery to charge or the battery to be used. But I already have a separate switch for the battery so I didn't do this :)
How much weight can it carry?
what sort of motor is this one, as i can get only one side ones, looks like you got left ones and right ones. what car did you get the ones from. thank you
+ary depaula These are AME 218 gearmotors that I bought from www.robotcombat.com/store.html
How fast can it go?
excuse my ignorance, but are the two middle wheels necessary? or would it disrupt the tension of the track if you use just use the front and back?
The middle wheels are necessary because the wheelbase is so long that when it turns, the tracks would twist on the ground (because they have a lot of traction)
That's one of the problems with these tracks I made, they flex sideways, not just up and down, which is why it can derail easily. I'm working on a new system using chains instead, hopefully that will work better.
Enderman LP yes, I just saw your video update 1 overview. I would love to see a quick video on how you made these tracks. Or the ones you are planning on making with the chains. I was thinking of doing some like these
letsmakerobots.com/node/26289?page=3
Enderman LP nevermind just finished watching this video
Vato P I still have to wait a bit before making the new version with chains...I had to look up the pricing of some custom gears and it would cost me over $700 just for the sprockets, so unless I can pull a bunch of $$$ out of somewhere, I'm going to have to keep looking for a more affordable option...
Can you provide a list of parts for this version?
eight 8" pulley wheels, two 72" V belts, two bike tires, 8 flange mount bearings, one sabertooth 2x25 speed controller, two AME 218 long shaft gearmotors, one 21AH lead acid battery, one DX6i radio+receiver, a bunch of wire and switches, many screws for the tracks, and some aluminum C channels and panels as well as nuts and bolts
@@EndermanEngineering Thank you for this, Im working on a project similar to this and I enjoy the content you make
@@icedevice4448 Thanks!
NICE! but can you stand on it?
yes, but I don't want to because the top is only a thin sheet of metal, only supported by 6 screws
I have sat on it tho, and it moves, but it has some trouble turning because of the traction the tracks have
its not meant to be something to move you around
I built this as a 'spy/surveillance' vehicle that can go all terrain with plenty of torque, but can also go up stairs and have a camera mounted on it
right now I cant really do that because my RC radio isn't 2.4GHz so I always need to be in LOS (line of sight), but I just bought a new DX6i that will let me control it behind walls and other non-LOS places
Needs track tensioner
de quelle machine viennent les poulies qui servent de roue,machine a laver ou seche linge, quelle marque,? merci
+Stephane Bond I bought mine from Canadian Tire, but its the same as these www.google.ca/search?q=8+inch+pulley+wheel&biw=1920&bih=959&source=lnms&sa=X&ved=0ahUKEwiqp52jkbTJAhUJK4gKHVPuDQcQ_AUIBSgA&dpr=1
where did you get those wheel/pulleys at?
Canadian tire, they were like $20 each.
This could be a battlebot
Well done on the tracks! I've watch your other video with the bolt mod on the driver pulley... I'm assuming that took care of the slippage. Question on the wiper motors: Did you get the LEFT & the RIGHT set? store.amequipment.com/218-series-gearhead-motor-64mm-12v-left-hand-p-350.html - store.amequipment.com/218-series-gearhead-motor-64mm-12v-right-hand-p-354.html Any chance you can post some video of it outside cruising around?
Thanks :)
Yeah I used the R and L motors, bought from TheRobotMarketplace
I'm planning to upgrade them to banebots geared CIM motors because those have over 5x the torque at the same RPM. I plan on posting more videos outside soon :D
Enderman LP Have you tried running them on 3s Lipos? So, are you satisfied with your tracks and the slippage issue? I've been looking for a simple solution of creating tracks and this bike tire method seems to be the ticket. On a side note...here's a infrared night vision FPV run I did a few weeks ago. vimeo.com/106080452 I've been wanting to build a track platform and you've inspired me.
NHTreasureQuest No, I don't have any lipo batteries :(
Currently I haven't tested the tracks with the anti-slip bolts yet because I need to drill through the wheels at school, and I just started school this week. I will post a video when I get that done. The vbelt tracks work well, but they're not ideal. If I try to pivot the platform on a high-traction surface like asphalt, the tracks derail. If its on cement or hard floor they're perfectly fine. I think this is just because of how heavy it is and the huge surface area that it contacts the ground. The only solution would be to buy $1000 custom made tracks and sprockets from superdroid robots. If the platform was half the size and weight there would be 0 derailing issues on any surface.
NHTreasureQuest That's a really nice remote crawler you made ;) Is that one of those small spy cams that people buy for RC? I avoided getting one of those when I built my platform because I was afraid of range and interference issues. The camera I bought was 2.4GHz and has 500ft range, but it cost $200. PS-I highly suggest uploading to youtube, there is a much larger audience that would love to see your creations :D
Enderman LP Interesting on the weight observation. I was planing on building out of plywood and smaller. I'm also going to look at brushless low KV motors. (Direct drive.) The $1000 dollar custom made tracks is exactly why I love your tire track idea. Get going on testing the anti slip bolts! :-)
can u inform width height and depth of your chassis ?
+Francisco Angelini the chassis is 4" tall and about 2x3ft, I cant remember the exact measurementsit is 9in tall including the wheels
Can you use two left motors?
Yes, but then you will have to cut the aluminum differently so they fit in opposite orientations.
how did you reattach the bike tire back to itself after you cut it?
Staples, and also a piece of rubber+glue (from a bike tire repair kit). The joint doesn't have to be strong at all, because all the tension is on the V-belt underneath which is a single piece with no breaks. The tire is just screwed onto the belt for traction and has no stress on it :)
I had so many question about the bike tire. Do you release any video on how on assemble the tire.
Just staples. Since the bike tire is screwed to the V belt there is no tension on it, and just regular staples held the ends together. There are screws every 2-3 inches. If you want you can also use a bike tire patch kit and apply the rubber+glue to make the joint stronger.
Enderman LP oh okay thanks ! I'm about to do something similar and got an inspiration from your vehicle. But I'm using an arduino and some servo motors
Cool! Good luck on your projects :)
where did you buy the motor controller?
the robot marketplace here:
www.robotcombat.com/store.html
Enderman LP thank you so much! :)
Enderman LP You're welcome :)
How much did the build cost?
Close to $1k.
TELL ME THE MAXIMUM LOAD IN KILOGRAM ?
nice wheels where u got ?
+Francisco Angelini Canadian tire, in store. For some reason they don't show up on the website. You can find similar stuff on amazon or ebay, and probably cheaper too
+Enderman LP i need living in canada kk here in brazil wheels like this $45 dolars 02 unities, 02 AME motors with import taxes U$ 269 :( saber tooth 2x25A U$240 and now dolar increase all day :( it´s time to think in moving. but nice project! i´ll doing one here! with mabuchi motor maybe 4 unities are cheap 9nm torque each.
+Francisco Angelini Ok, just make sure you build a smaller version, or youre going to have problems with the tracks on high-friction surfaces that aren't a flat smooth floor. In one of the other tracked vehicle videos I talk about how the v-belts don't like to stay in because of how large the vehicle is. I'm currently working on a new track design using chains that will hopefully not derail when used on such a large vehicle, but it looks to be a bit too expensive at the moment
+Enderman LP wow thx, maybe i´ll using bike chairs with rubber and smaller wheels like baby cars dual in front and back with bike gear to chair don´t lost contact or friction.
i see now in 1st frames sorry thx
Sowas auf RUclips hochladen? Ist ja den Aufwand nicht wert... das ist der Kinderbausatz von Fischertechnik nur als unflexibler Kasten aber okey. Wie wärs mit Solarzelle am Gehäuse, oder Kamera vorne drinnen mit Live-Übertragung? Dann wäre es einen Upload vielleicht wert

please contact me. i'm needing a vehicle like this
What is the cost to build it?
About $1k
@@EndermanEngineering ohh its cost is to high
Do you sell these?
+Rob Peterson No, I don't think its worth selling because it has several flaws that make it impractical (*which I will be fixing in Version 4) and the parts are expensive. If you do want something like this I would suggest going to google "superdroid robots" because they make tracked vehicles just like this one, with actually professional grade construction and a lot of testing to make sure they are 100% reliable
I buy it so that info me
Would you sell it?
150$ on hand :)
This project has cost at least $1k so far, and it keeps increasing...
