Abstract
A robot controller for use in a robot control system with a plurality of robots connected one another through a communication path. When a cause for stopping occurs in one or more robots, other robots are also stopped in the same type of stopping procedure. A priority of execution on a plurality of stop procedure types is determined. When a cause for stopping occurs in one or more robots in the robots connected through the communication line or in the robots in synchronously cooperative operation, all of the robots connected through the communication line or the robots in synchronously cooperative operation are stopped in the same type of stopping procedure. If different causes for stopping occur in the robots, a stopping procedure type having higher priority in the stopping procedures determined in accordance with the different causes of stopping is adopted to stop all of the robots in the same type of stopping procedure. Since the robots are stopped in the same type of stopping procedure, displacement of relative positions of the robots in synchronously cooperative operation is made small.
