Control device, grease cooling method and management device

A grease cooling method executed by a control device configured to control a robot including an articulated arm having a plurality of joints each provided with a motor and turned by driving of the motor, and a base supporting the articulated arm, the method comprising:

• a temperature information obtaining step of obtaining temperature information about each of the plurality of joints;
• a joint specifying step of specifying one of the joints that requires cooling, based on the obtained temperature information about each of the plurality of joints;
• and
• a motor control step of, when the joint specifying step specifies one of the joints, controlling the motor of at least one of the joints that is located on a side of the base from the specified joint so as to turn the joint on the side of the base from the specified joint for a given time.

A management device configured to manage a plurality of robots each including an articulated arm having a plurality of joints each provided with a motor and turned by driving of the motor, and a base supporting the articulated arm, the management device comprising:

• a temperature information obtaining unit configured to, for each of the plurality of robots, obtain temperature information about each of the plurality of joints;
• a joint specifying unit configured to, for each of the plurality of robots, specify one of the joints that requires cooling, based on the obtained temperature information about each of the plurality of joints;
• and
• a motor control unit configured to, for each of the plurality of robots, control the motor of each of the plurality of joints, wherein, when the joint specifying unit specifies one of the joints that requires cooling, the motor control unit is configured to control the motor of at least one of the joints of the robot that is located on a side of the base from the specified joint so as to turn the joint on the side of the base from the specified joint of the robot for a given time.
