Abstract: A robot system includes a workpiece supplier, a work robot, and a support. The workpiece supplier is to turn a workpiece about a workpiece turning axis to position the workpiece at a work position. The work robot includes a base and a robot arm. The robot arm is connected to the base turnably about an arm turning axis to perform a work on the workpiece at the work position. The arm turning axis crosses the workpiece turning axis. The support connects the workpiece supplier and the base.

Abstract: A robot arm includes a first member, a second member, an actuator, and a speed reducer. The second member is pivotable relative to the first member about a pivot axis. The actuator is configured to pivotally move the second member relative to the first member about the pivot axis. The speed reducer is configured to couple the actuator to the second member to reduce a rotational speed of the second member relative to an output rotational speed of the actuator. The speed reducer includes a grease chamber in which grease is to be provided. The second member including an air chamber in which air is provided, the air chamber being connected to the grease chamber.

Abstract: An internal pressure adjustment system includes a gas supply line that supplies incombustible gas to a housing space of a robot, and an exhaust line that exhausts gas from the housing space. The internal pressure adjustment system further includes an on-off valve of a gas pressure driven type that switches between opening and closing of the exhaust line in accordance with the gas supply pressure. The exhaust line is opened in response to an increase in the gas supply pressure and the exhaust line is closed in response to a decrease in the gas supply pressure.

Abstract: A robot system includes a robot, a moving body, a determination circuit, a calculation circuit, and a control circuit. The robot includes a mount and a first arm. The determination circuit is configured to determine a lastly moved part of the robot which is lastly moved to make the robot take an operation posture. The calculation circuit is configured to calculate, based on the lastly moved part, an angle between a travel direction of the moving body and an orientation axis of the first arm when the robot in the operation posture is viewed along a height axis of the robot. The control circuit is configured to control the robot to work on a workpiece keeping the robot in the operation posture with the calculated angle while controlling the moving body to move in the travel direction.
