holonomic drives

[Ryan M.]

I don't have any actual expertice, but I'll just say that those are hard to build, but tons of fun to see in action.

I have done some programming for something I constructed out of LEGO Mindstorms once, so I might be able to offer some advice if you have something specific. Feel free to PM me, the worst that could happen is I don't know and have to yell at you cover my lack of knowledge.

P.S. Mindstorms is great. Check out my avatar for some of the cool things you can do. And I got it to Mars with less than those NASA guys.

Actually, it's not much harder than any other FIRST bot unless you decide to machine your own omniwheels. The toughest part is independently powering all 4 wheels, but some teams do this anyway on their 4-wheel drive bots.

Sorry for being ignorant, but what exactly is a holonomic drive?

[Solace]

technically, a holonomic drive is a drive that allows you to move in three axis at once (i.e., going forward, left, and rotating). examples of a holonomic drive are 857's kiwi drive (killough platform) or the technocats ball drive.

a swerve drive is not truely holonomic, but for FIRST robot purposes it is close enough. a swerve drive has the wheels rotating seperately from the robot orientation.
