Check it out, the easiest two speed shift on the fly ever. Had a working prototype an hour after the belts and pulleys came in. Hopefully after the build season I'll have time to post a simple white paper on how to make it yourself(not that its any more complicated than what you see.)
Next a video of our bot in action. Everything minus its capping mechanism since all I have to work with is week old video.

You'll get some nice footage of our Bumper System doing what it does best. Stopping other bots dead in their tracks, no matter what.
GO GO GODZILLA!
