Once upon a time, in a flame war almost forgotten, there was a cool video put out by VEX on how robust the VEX EDR system was. It showed someone standing on parts and a robot pulling them around in a chair. It was one of the smaller employees (I think JVN, but I can't find the video to check).
One of the VexIQ enthusiasts built a skateboard.
Here is a video of him riding it. Not bad for plastic you snap together.
