Abstract: A robot system includes a robot and a robot controller that controls an operation and a temperature of the robot. The robot includes a first joint, a second joint, a first drive mechanism that drives the first joint, and a second drive mechanism that drives the second joint. A temperature adjuster includes a temperature sensor that measures a first temperature of the first drive mechanism, a heater that heats the first drive mechanism, a temperature sensor that measures a second temperature of the second drive mechanism, a heater that heats the second drive mechanism, and an adjustment section that controls the heater so that the first temperature of the first drive mechanism approaches a first target value set in advance, and that controls the heater so that the second temperature of the second drive mechanism approaches a second target value set in advance.

Abstract: A control method for controlling a robot includes a measuring step of measuring a temperature of measurement target of drive mechanisms from among a plurality of the drive mechanisms at predetermined time intervals by a temperature sensor included in a temperature control device, a heating step of heating the plurality of the drive mechanisms by heaters included in the temperature control device, a stopping step of stopping an operation of the plurality of the drive mechanisms by a robot controller, when the temperature of the measurement target falls below a set stop temperature, and a resuming step of resuming the operation of the plurality of drive mechanisms when the temperature of the measurement target is equal to or higher than a set resume temperature after the robot controller 500 has performed the stopping step.

Abstract: In a dust removal apparatus, a front air nozzle unit emits air jets onto a region of a workpiece surface near a rotary brush along a linear front end edge of a hood covering an upper half portion of the rotary brush. Rear air nozzle unit emits air jets onto another region of the workpiece surface near the rotary brush along a linear rear end edge of the hood.
