Twitch:

Type: Tread-mounted Inspector Bot
Operation Notes: Inspector Bots determine if units, products, and working conditions in the factory are safe. As a result, they have full working knowledge of everything that could possibly go wrong and are instructed to go and seek out problems. Inspector Bots twitch at bright lights, loud noises, sudden movement, or nothing at all. The typical Inspector Bot is convinced that the robot next to it is about to go mad and would send out a warning by radio if it didn't know how dangerous even that was.
Factory Task: Site and product inspection.
Unit History: EEK-47600-J did an overall site analysis and determined that the most dangerous factor in a robot's environment was its control computer. EEK-47600-J was placed in the current RoboRally almost instantly.
