Robot controller

A robot controller that receives a signal transmitted by a wireless device mounted to a robot that is a control target, the signal including data of an operating state of the robot, the robot controller comprising:

• a first receiving unit that receives the signal including the data from the wireless device mounted to the robot;
• a transfer unit that, in a case in which the signal received by the first receiving unit is a signal from other robot not to be controlled, transfers the signal to other robot controller controlling the other robot;
• a second receiving unit that receives the signal transferred from the other robot controller;
• and
• a signal processing unit that determines whether or not the signal received by the first receiving unit has an outlier value exceeding a predetermined allowable variation value, and upon determining that the signal received by the first receiving unit has the outlier value, determines whether or not the signal received by the second receiving unit has the outlier value, wherein the robot controller controls the robot using one or more of the signal received by the first receiving unit not exceeding the predetermined allowable variation value and the signal received by the second receiving unit not exceeding the predetermined allowable variation value.
