 I can't wait till FIRST starts giving anti-gravity kits inside the kit of parts. - Rob Colatutto [more] |

Bicycle Drive?
Bicycle drive would consist of a swerve module in the front and a free-spinning traction wheel in the back, with the CoG perfect centered on the line connecting the two wheel axles. It would drive like a bicycle.
This seems easy enough to build for some team with a spare swerve module. Has this been done before? If so, anyone have some video of it?  Of course, bicycle drive would be useless for a real competition since it tips far too easily and require constant movement to stay upright. Seems like a fun offseason project though, especially on the software side with auto-balancing code.

Re: Bicycle Drive?
How would code balance a robot with one wheel in front of the other?

Re: Bicycle Drive?
Why not just take a bicycle and attach a servo or VP to the handlebars via a sprocket or gear? Then you just need the gyro and encoder, no swerve modules or anything necessary.

Re: Bicycle Drive?
Check the 2008 robot from 1318 Issaquah Robotics Society. They called it the "Killer Rabbit". It was a lap runner following the same strategy 148 used with Tumbleweed. There is some video of it on The Blue Alliance. As I recall, it struggled with falling over during the first regional they entered, but by the 2nd regional they performed well enough to rank #2. I think it ended up with outriggers to keep the wheels on the carpet when it would tip so it could recover.

Re: Bicycle Drive?
An autonomous motorcycle was entered into the first? DARPA autonomous vehicle "grand" challenge (The first of the two (the off-road one) challenges held a few years ago that were intended to give the autonomous ground vehicle industry a big boost).
A little internet searching should turn up info about their methods, and about the general topic.
