The season has already lasted for about 4 months and most teams should already have a basic robot design settled. What type of drivetrain do you use? I know I’ve been making lots of votes recently but the results seem to be interested. Please PM if there is an issue
Furthermore, do you chain your drivetrain together?
What would a six-wheel with bolted omnis count as?
what is a crab drive may I ask?
Really? No other X-drives?
Locked omnis.
Also @CarCar can you separate traction and omni drives?
I chose traction drive, but only because all 4 of my wheel are the 3.25 in traction wheel
I also doubt that most others are using that setuo.
Yes I think I did lemme check
Yes I did do that wrong but it can no long longer to changed
Traction and omni or other
I drive that rotates each wheel and has its own drive motor
Chaining drivetrain is wack, always scared it’ll break.
that’s a swerve drive. no idea where you got the name crab drive from…
Have the motors attached directly to the wheels then chain the wheels together so if the chain breaks it’s basically just a direct drive while you still have the benefits of a chain drive.
But what are the benefits of a chain drive?
So if all your motors are chained together and a wheel starts slipping or gets raised off of the floor the energy from those motors is transferred to the wheels that still do have strong traction. It really helps with climbing and pushing. It’s just more efficient.
on top of that it helps with robots that have uneven weight distribution. say your bot is front heavy. If you don’t chain your drive your front motors are undergoing more stress than your back ones. The chain helps even that load so the motors overheat more slowly and more evenly (if that’s the right way to put it I’m not sure)
EDIT: your robot’s CoG should not be significantly offset to the left or right. Then there would be no way of making up for it except for weighting the lighter side.
It can drive the robot as if it were a crab.
Isn’t that just an H drive
so can an h drive, an x drive, and a mecanum drive. These drives can also move in directions similar to most large animals on earth. if you made a base with 8 legs and pincers that crawls side to side, then the term crab drive would be acceptable. otherwise, stick to using good terminology please.
yes that was what I was referring to swerve drive, but as a mentioned it’s able to drive the robot like a crab.
