Abstract

Abstract PURPOSE:To prevent abnormal operation due to an earthquake by providing an earthquake control means activating a controller with an output of an earthquake detector detecting the vibration exceeding a prescribed value so as to activate a robot controlled by the controller at an earthquake. CONSTITUTION:A robot 5 is controlled by a controller 6 and then operated. An earthquake detector 7 detects the vibration exceeding the prescribed value and gives an output. When the robot 5 is in job operation, the detector 7 is operated for earthquake detection, an earthquake control means 8 activates the robot 5 at an earthquake via the controller 6. Thus, the operation by a job operating means 14 is stopped and robot comes to a standstill. Thus, the abnormal operation of the robot 5 due to earthquake vibration, generation of abnormal operation due to a damage of an electric circuit by the earthquake vibration are prevented and the secondary defect due to the earthquake is prevented in advance. When an earthquake termination detector 9 is not in operation, the operation at earthquake is continued.
