Oh, and this: were the rollers free-spinning? Or were some (or all) binding?


The wheels were all free spinning. The marks appeared primarily when that wheel was powered, so going forward left 4 trails, while going diagonal only left two from the wheels being powered. the distance between marks remained consistent regardless of speed, while their intensity increased the faster the robot went. When changing rapidly from one direction to another the marks got substantially worse (darker).
