This is the second year that I DON’T KNOW WHO? competes at Robot Ruckus in the Gladiator division. It is a small, red robot made of PET-G and titanium. Along with the robot’s new double-wall body, I DON’T KNOW WHO? features Repeat Robotics drive motors and a FingerTech Robotics weapon motor. The wheels are made of silicone rubber, and also new to this year, the weapon is a 3-prong blade that spins horizontally.
