A bot-auto repair is an Interior Structure put in the Robotics Facility that robots will go to when they reach a critical condition. However, this cannot repair overall integrity and a robot will eventually be disassembled. This repairing process takes an average time of 5 seconds (if the robot has half of their integrity down). This is an advisable and easy technique, as engineer no longer must tend to the bots. That is if you can pay 2 semiconductors and a metal.
