Re: pic: Crab Drive Prototype Weekend Build
Is it still a crab drive if you have two non-rotating wheels in the back?

Re: pic: Crab Drive Prototype Weekend Build
This looks really fun and easy to build as a summer project, even for me!

Like Craig said, nice job boiling it down to the basics. Great work.

Re: pic: Crab Drive Prototype Weekend Build
Applause, I think this is testament that any team can do it if they can come up with a simplistic design tailored to your team strengths. For example if you don't have anyone to weld, don't put in welding, if you have little machining capabilities, use a tough box.

Re: pic: Crab Drive Prototype Weekend Build
Interesting concept! This is a creative way of building a crab drive for low budget teams.

Thanks for sharing!

But each wheel is individually controlled, but can be linked in software.
