An operation system of a robot arm includes the robot arm disposed in a work box which is sealed, an operation apparatus disposed outside the work box and including an operation device which is operated by an operator to input an operation command of the robot arm, a control apparatus moving the robot arm based on the operation command from the operation apparatus, and a reaction force controller. Based on movable region information which indicates a movable region of the robot arm in the work box, as the robot arm approaches the limit of the movable region, the reaction force controller increases a reaction force which is against a force of moving the operation device by the operator in a direction approaching the limit of the movable region. |
