I totally agree with you (although maybe not calling the test a "test" ). I don't have access to this stuff currently, but I'm actually surprised someone hasn't done the sharpie marking with a closeup of a robot moving. Anyone with a good mec drivetrain, sharpie, and smartphone/gopro out there??????

yes, it would be better if the axle of both wheels were actually attached via some structural members, and the traction wheel width was as wide as necessary.
Anyone with some bored underutilized students, a spare mec wheel and extra wide traction wheel of the same radius out there??
