Abstract: This positioner comprises: a first member; a rotating table supported to rotate about an axis relative to the first member; a motor that is parallel to and offset from the axis and drives the rotating table; a reducer disposed between the first member and the rotating table, reducing the rotation of the motor and transmitting the reduced rotation to the rotating table; and a power cable for supplying power to the rotating table. The first member and the reducer are provided with a hollow section passing therethrough. A current collector brush is attachable to and detachable from one end of the power cable. The power cable extends, from the first member in a direction away from the rotating table. After being bent into a U-shape, the power cable passes through the hollow section along the axis, and one end of the power cable is detachably secured to the rotating table.

Abstract: A robot including a robot mechanism including joints and drive units, a control unit controlling the drive units so that an inspection operation to inspect one target drive unit among the drive units is executed by the robot mechanism, and a notification unit notifying maintenance information of the target drive unit based on a current value of a motor of the target drive unit during the inspection operation, or on information associated with the current value, and the inspection operation includes transmitting, to the motor of the target drive unit, control command to rotate a joint as much as a predetermined rotation angle, and thereby moving a tip of the robot mechanism or a tool at the tip, close to an object at a predetermined position from a predetermined start position, to press the object, and separating the tip of the robot mechanism or the tool away from the object.
