I wrote up a profile on a VEX demo bot that was designed by one of my interns.
This was the challenge I issued him:
“Build a robot which will play the game ‘Swept Away’, is easy to mass-produce, is durable enough to run as a demo robot with minimal maintenance, and is cool enough to showcase VEX well.”
See how he did in my writeup here:
