Can't wait to see pictures/video showing the drive mechanism.

How are the current competitors steering?
From the video, it looks like car steering.

4276 designed a linkage steering mechanism which produces a +/-30 degree rotation to the front pneumatic wheels (powered by a PG188 gearmotor and PID controlled with an encoder). The rotation is mapped to an actual USB steering wheel the students use to drive, and acceleration/brake pedals to control drive acceleration from the rear pneumatic wheels.
I will get some photos to share tomorrow, I just realized I hadn't taken any good ones of the linkage and robot internals yet.
We also have an FPV system onboard with a wide angle lens to see live robocam views and to record the same view.
