    • A safety method in a robot system including at least a robot (1), peripheral equipment (2-5) serviced by the robot, a robot control unit (6) which causes the robot to execute predetermined services for the peripheral equipment, and a teach control panel (9). A door (11) is provided at the entrance to a robot operating zone, and the door is provided with a safety switch (12) for terminating automatic operation of the robot when the robot is in an automatic operating state. When the safety switch is actuated by opening the door, robot motion in the automatic operating state is decelerated and stopped. During the time that the safety switch is in the actuated state, the robot is placed in a playback operation state to enable control that is performed through the teach control panel.

    • A uniform velocity control method for rotating a first movable element (3) at a uniform velocity in a rectilinear-to-rotational motion converting mechanism, in which a second movable element (2c) is moved along a linear shaft (2a) and the first movable element is rotated in dependence upon rectilinear movement of the second movable element. The uniform velocity control method includes (1) a second step of monitoring a position of the second movable element along the linear shaft; (2) a second step of calculating a traveling velocity of the second movable element, which traveling velocity is for rotating the first movable element at a uniform velocity, in dependence upon the position of the second movable element along the linear shaft; and (3) a third step of moving the second movable element at the calculated traveling velocity to make the rotational velocity of the first movable element uniform.

    • An acceleration and deceleration system smoothly controls acceleration and deceleration of an electric motor for driving a movable member of a machine tool or a robot. The acceleration and deceleration system has a linear acceleration and deceleration circuit (3) for receiving interpolation data issued from a pulse distributor (5) and effecting a linear acceleration and deceleration computation on the received data, and an exponential acceleration and deceleration circuit (4) for receiving an output signal from the linear acceleration and deceleration circuit (3) and effecting an exponential acceleration and deceleration computation on the output signal, the circuits (3), (4) being connected in series with each other. The exponential acceleration and deceleration circuit (4) reduces abrupt changes of the controlled speed which are a drawback of the linear acceleration and deceleration circuit (3) prevent shocks from being produced when an axis starts moving and is decelerated thereby providing smooth and accurate acceleration and deceleration control.
