Abstract
A robot determines whether or not an operator or an object is jammed between a robot arm and an external structure, classifies an area in which an end portion of the robot arm moves into a restricted area and an unrestricted area, and sets a restriction period. If a period after detection of the jam is in the restriction period and the end portion is in the restricted area, restriction on movement is imposed on one or more joints of the robot arm. The restriction on movement is a stoppage of movement of one or more joints. If the period after detection of the jam is after the restriction period, the restriction on movement is removed. If the period after detection of the jam is in the restriction period and the end portion is in the unrestricted area, the restriction on movement is not imposed on the joints.
