One of the most advanced projects! JudoBots are hydraulic-powered machines that grapple with each other. The goal is to build a bot that can flip the opponent over, or push them out of the starting square! The pivoting and lifting mechanisms are identical, but the base, arm, and grappling tool are customizable.

The base must fit within a 10x10" square, and no more than 40 craft sticks can be used to build the entire bot.
