Re: Butterfly/ octocanum drives

A couple years ago our team built a 'slide' drive that used two omni's that were in the middle to translate us and four omnis at the corners to drive. It was terrible, but that's where I first learned of these concept drives.

At the time it occurred to me that you could use something equivalent to a starter bendix drive to push-down the translating wheels only when you need to strafe. In a starter bendix, it moves forward to engage your flywheel using the rotation of the motor--Simple, no space-hogging pneumatics on the frame. I have'nt tried it but I'd be interested Yes, a bendix only moves foreward on one rotation, but I think you could use the concept to design a bendix-in-a-bendix and make one that moves down on both rotations.

And then it occurred to me that this might be better with four-wheels for strafing and four wheels for regular driving . Then I thought why do we even need omni or mechanam wheels for this?

So why does an 'octonum' or any of these others even need translating wheels? If your goal is to strafe, can't you just do that with 'good' wheels?
