Re: Different Swerve Drives

Thanks for the update of the info.

As an FYI, team 1640 is in their 4th season of "Unicorn" drive, 2010,2011,2012 and this year, 2013. Their fabrication info is on their website.

I've only seen them in practice driving it. This years incantation is quick and agile. There also seems to be some mind-meld of the driver and control system from the demos of Dewbot IX swirling around the base of the tower.

Check them out at the MAR districts.

Re: Different Swerve Drives

Slip rings are reasonable for this application. Consider that the current that is commutated (sp?) in DC brushed motors goes through an interrupted slip ring.

You could make your own with copper tube, some insulators, and carbon brush blocks. To cut losses, use more blocks.

What's difficult is getting a clean signal across a slip ring.

Not on a competition robot you couldn't, unless the rules changed. R49 says any slip rings must be COTS.
