Hey everyone! Back in Scrap Mechanic Creative and today I work on prototyping omnidirectional, or mecanum, wheels in order to make a tank that can strafe and move diagonally without having to turn! Thank you to @kANGaming for the help! Make sure to check out the video and I hope you guys enjoy the build! See you in the next one!
Thanks for watching the video! If you enjoyed it, make sure to like it, share it with your friends and give me your feedback in the comments below!

About Scrap Mechanic:
Scrap Mechanic is an all-new creative multiplayer sandbox game which drops you right into a world where you quite literally engineer your own adventures! Choose from the 100+ building parts you have at your disposal and create anything from crazy transforming vehicles to a house that moves. You’re even able to team up with your friends to create amazing things together: in Scrap Mechanic, you’re the master creator of anything you can imagine!
Here’s the deal: you’re a robot maintenance mechanic en route to your posting on a fully-automated agriculture planet. Your job is to take care of the worker robots as they work the land, sending the food they produce to the metropolitan planets. Thing is, close to touchdown your spacecraft loses control and crashes, but since you’ve got luck on your side (erm…), you survive! You’re stranded though, and at first glance you find that not everything’s quite as it should be. The Farmbots working the fields have gone crazy, and now there’s only one way to stay alive: using your quick thinking, your creativity and your wily knack of turning your surroundings to your advantage.
For a while Mythbusters had a forklift with this system. I believe it used two joysticks just for directional control, plus another for the lift part, but they showed it off in one episode and it was amazing what it could do. I do also remember seeing a project (basically a go kart) in an old magazine that used a different omni-drive system, but used a horizontal hoop as the control input. Essentially the kart would replicate the movement of that hoop (directional and spin-in-place).
Also nice that you had a robotic thing at your school. All i got was farming.
I gotta say, I like to watch Scrapman for his creativity, I like to watch Kan for his engineering, but I love watching Kosmo for his positivity.
For a WASD converter, you need a bearing for seat-steering, a bearing and a controller not on loop for seat engine, and 4 sensors in total. There might be a slight delay, if you don't have max-level seats and max-level controllers, but it works.
A nomad multiplayer series would be nice, especially since it could be over much quicker than a normal series for which you're making a base. I think the same rules as Scrapman's series would work, but one vehicle per person, and they have to be specialized vehicles. Of course, the others can move the base around while the others are offline, and quickly move to a designated area before logging off, from where others to be able to pick up the mobile base or particular vehicles.
After seeing this i'd be interested in seeing you build some sort of strandbeest.
I'm kinda surprised that you didn't need to use pistons to increase the wheels radius while on the lift, and smaller distances between ground contact when on the ground.
Ok ok, hear me out, guys. Chapter 2 survival with Kosmo, Kan and Scrapman all together in a mobile walker base! Yeah, I know, sounds too good to be true :(
Oh, and by the way, really cool video, Kosmo! :)
I agree 💯
Man i wish
Probably not mobile base but the trio multiplayer survival would be very dope
Dude it would be a blessing to have them in the same world lol
If that ever happens, no one would be watching. Cuz even if they decide to upload, hardly anyone would stick around to bare with the 10-15 fps for the episodes in and after they get the mobile base.
Honestly, im with Kan and I'm with Kosmo on thus stuff.. I understand logic like kan, but I dont want to, like Kosmo. Lmao.. honestly, once you figure out bits and logic loops, it becomes easy. Kans facecam tutorials from 4 or 5 yr ago helped a lot.. love the video, love the creativity. Wish I had an idea to give uou to build, but im always going to tune in. Love the content man.
Axolot needs to add a system where the connection tool is able to highlight one set of connections and not just all of them
I am part of a Vex Robotics team and we are using these wheels. Thanks for the great content!
Vex homie!! We use xdrive.
No way! I was literally thinking about doing this last night. I also do FIRST robotics and I was thinking about how cool it was last night. I'm actually a senior this season and I'm our build lead. We're doing 8 of these wheels this season to make a mechanum robot that can climb over obstacles.
hey! I’m in ftc too! Going to a scrimmage tomorrow! How’s your robot doing?
@@abrokendowncar Awesome! We're currently #3 worldwide for the remote games, with a highscore of 209.
@@DigitalJedi wow! What’s your team name/number?
@@abrokendowncar I'm on The Javengers, team 8468. I may be a bit off in the exact leaderboard spot, it's been a while since anybody here checked.
@@DigitalJedi cool! I’m from team 4531.
nice to see another fellow FIRST mech lead
good to hear that you and KAN are gonna do some new co-op content in the future!
Kosmo! The really big connection points bothered me too. Get the 'better connection points' (I think it's called) mod! It makes the points smaller and less glitchy. Much easier to see what you're doing.
im guessing scrapman gonna make a crab next
Hey I also was the mechanical lead on a first robotics team, we made it to worlds in 2019 for the space themed one
Kosmo. You’ve gone insane
😂
Man this gave so much coop vibes 🤩
Dang kosmo! Your creations have been really cool lately!!!!
This perfectly explains why Kan does programming and why Kosmo does mechanical engineering, lol.
I watched a few vids on this subject before this video popped up, so I get it. Maybe Kan should have done a little research, lol
The solution for the free floating bearings would be more engines, but then the wheels would need double bearings and instead of freefloating when strafing they would be powered in the right direction. They would have more grip when they need as you can stop them from turning
I'd love you see you and scrap man race your ancient planes.
You guys should do a hot air balloon fly over the old map remembering funny times and showing clips to those wacky moments.
I’m in first robotics right now
maybe a dumb idea, but i know because in scrap mechanic from a front view the wheels are perfectly square, so when rotating only the corners hit the ground, and when the wheel is perpendicular to the ground, it's bounced in the air already, so what if you tried lower physic levels? by making the bearings floppier i believe the wheels may contact the ground much better and potentially even make a smoother ride.
So I am an FTC coach there are are a few things people forget about them. First is the gap between the wheels is to large here making it bounce and sometimes only having contact with the ground at 2 points instead of 4. Second is that the rollers need to have an arch which allows them to smoothly transfer weight from one roller to the next. This game is just limited in its physics for that to work any better than you have. Like the hill problem would not happen in real life because the 45 degree rollers pull/push against creating equal forces making it able to climb slopes. This is like snow skiing and pointing your skis in to come to a stop. The game just doesn't have the physics for that. I think you might have made the closest thing to true mecanum wheels you can in this game.
the fact that kosmo is always happy make me happy
Next step build racing with the boys
I have the same problem with programming in Scrap Mechanic.
It's all just a blob and I've no idea where what goes.
Wish it'd only highlight the connections You're hovering over and everything else would be black and white or not even there.
Or have a list of all connections and connectables, that'd be perfect.
Something like a programmable controller... and different shading for connections hovered over?
Yeah that's a thing i would wish we had too
@@Luziferne Yeah, pretty much like that
You have to increase the angles on the wheels to increase the friction
But then the strafing ability is lessened. Mechanum wheels work because the 45 degree angle allows for the same speed in normal motion as well as translational side to side motion. This is what gives them the ability to move on diagonals and spin around any corner, center of any side, or the center of traction.
Okey that was good. Now its time to make a origami transformable wheel
16:48 i knew it!
coop idea - clear all warehouses using mechs only
Kosmo, /aggroall isn't the right command, it just alerts the bots of your location but doesn't make them want to kill you. That's another command, /aggrooff I think.
Omni-wheel next?
Put all the wheels on a gas engine at the lowest setting. Maybe that'll stop them from sliding, but won't stop them from rolling when you put power to them...
First robotics is god tier
Have you guys raided a warehouse with explosives as your main weapon of choice? I mean it's pretty dumb and ludicrous to do, but that's content right there. You make a canister launcher that can be moved around in the warehouse and you basically have to set it up, and launch a canister at a tape bot first before you are able to whip out your spud guns. You're able to smack down the tape blocking the doors and try to trick tape bots into shooting canisters you set up right next to them, but the main point is that you're running amok in the warehouse with explosives.
Build a screw propelled vehicle ("Шнекоход", developed in Russia, also known as ZIL-2906 and ZIL-4904) that uses screws to move across mud, water, snow, sand.
< thinks to himself as he is clicking on the thumbnail "This looks kind of like the forklift I used use"
Wheel of wheels
If the bearings aren't powered, they're not needed. Wouldn't having fixed wheels make it faster?
It would but then it would also limit the range of movement to where you might as well just have a regular wheel
Maybe you could impove it with the sticky wheels when chapter 2 comes out.
Interesting 🧐
Maybe add a switch to rotate the wheels (the small individual wheels) so that they are at a right angle to the vehicle so they don't roll by themselves when you go forward if you know what I mean. Like if you had a normal car and rotated the wheels 90 degrees
Lol. What if you had a co op episode or mini series where you guys play in creative mode on a survival map and show us the difference between survival and creative or to be fun troll us all aka trick us or each other until cheaper 2 comes out because right now its taking a long time. Or try to use mods to trick each other and maybe trick scrap man or moonbo with a few things just to get everyone together.
Is this possible in survival, or does the fps die with less bearings than in creative?
made one 2 years ago. also made one a few weeks before you recorded this
you should make a paddle steamer
oh man i love first robotics.
After six comment on scrapman you made it
Amazing
you should try playing descenders it is a fun game it is also multiplayer
Why did the co OP survival end?
Well it didn't end per se, but it's on hiatus till ether they have an Idea worthwhile or chapter 2 is hitting. Or at least that's how i understand it
Ты топ)
You are top)
Try besiege for omni directional building
Make the best scorpion fighting or last to leave the game
hiii friend kosmo
ah, we use omnidirectional wheels now. i wish we could still use the mecanum wheels, but they are considered legacy.
@@lechking941 yes. the rollers are perpendicular to the hubs, as opposed to the mecanum wheels, which are at 45 degree angles. you still have to use a pair of regular wheels in the back, to have traction, but they work much better and are easier to control.
@@lechking941 Yes. you can have 4 mecanum wheels, but not 4 omni.
Do Trailmakers survival plzzzzz
Still waiting for chapter 2...
robotics? show show show show show!!
At this point, I feel like he's confusing the two games too much.
It's only Trailmakers that weld unnecessarily every part to everything.
ScrapMechanic will not weld it unless you use the tool and weld it.
@@lechking941 Kosmo...
Hi
ayyyy im doing first now its amazing!
hi
The strafing wouldn't work at all without the free bearings, as the thing that makes the strafing work is that the force is applies perpendicular to the free wheels, like how the keel of a sailboat redirects force from the side to the front. Without the free bearings, you just have lumpy wheels. Kan knows nothing about how omnidirectional wheels work.
for improving your creation, my recommendation would be to have three square hubs rotated 30 degrees with respect to each other rather than one hub with wheels on the sides and corners. This would give 12 wheels all at the same distance from the center, rather than 8 at different distances. I also would have used T pipes with a wheel either side, to have more width more evenly. Unfortunately, the main thing you need is more resistance to sideways slipping of the wheels, and scrap mechanic wheels slide like greased butter, so you can't do all that great. Maybe putting suspension on the 4 main axels, if that didn't lag too much.
Can I name my new car after you?
YOO I do FRC
those are mechanum wheels not omni wheels XD
