摘要： A method for producing an arm structure in which the arm structure is produced by: forming an arm precursor member having an external shape of the arm structure by, in a state in which a die is closed with a metal pipe member being disposed in a cavity thereof, pressurizing the pipe member with liquid supplied to an inside thereof to cause an external surface of the thus expanded pipe member to be pressed against an inner surface of the cavity; and forming a flange portion to be attached to a driven body by machining at least an end of the formed arm precursor member.

摘要： Provided is an industrial machine including a base including a through hole vertically passing through the base and installed on an installation surface F using a fastener through the through hole and a friction reducing member configured to protrude from a bottom surface of the base to reduce friction between the base and the installation surface. The friction reducing member is lowered below the bottom surface of the base during relocation and raised to the same level as or above the bottom surface of the base during installation by a vertical force applied to the base using the through hole.

摘要： A rotary axis module includes: an input shaft connected to a drive motor; an output shaft, an output shaft flange connected to the output shaft; parallel gears coupled to the output shaft flange; at least two double gears; and a transfer gear that transmits the power of the drive motor to the double gears. The at least two double gears and the transfer gear are disposed so as to surround the output shaft.

摘要： A control device for a robot includes a comparing unit and a controller. When the robot equipped with a force sensor capable of detecting force components of a same type in a plurality of directions operates, the comparing unit compares a magnitude of each of the force components detected by the force sensor with a predetermined threshold value for each of the directions. If the comparing unit determines that a magnitude of a force component in any of the directions exceeds the threshold value, the controller controls the robot to avoid an increase in the magnitude of the force component in the direction.

摘要： A robot system includes a robot main body, a sensor that detects a magnitude of an external force applied to the robot main body, a control unit that controls the robot main body, a reference value storage unit that stores a value of an external force detected by the sensor as a reference external force value in an operating state where only the weight of the robot main body and the load handled by the robot main body act on the robot main body, a determination unit that, during operation of the robot main body, determines that an external force other than the weight of the robot main body and the load acts on the robot main body when an absolute value of a difference between a value of an external force detected by the sensor and the stored reference external force value is larger than a predetermined threshold value.
