Abstract: 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.

Abstract: A gap detection device includes: a measurement unit measuring the driving torque or current value of a motor when the robot is actually being operated along an arbitrary motion trajectory; a simulation unit setting an arbitrary second gap amount between pairing elements of a plurality of pairing elements, performing a simulation in which the robot operates along the same arbitrary motion trajectory, and estimating the driving torque or the current value of the motor; a feature amount calculation unit calculating a first feature amount indicating fluctuations of a value related to the measured driving torque or current value, and a second feature amount indicating fluctuations of a value related to the estimated driving torque or current value; and a gap calculation unit calculating an index related to a first gap amount on the basis of the first feature amount, the second feature amount, and the second gap amount.

Abstract: A device and method for judging the presence or absence of an abnormal clearance between paring elements of a passive joint of a robot. The device has sections configured to: calculate a score for each motion path, wherein the score is increased when the paring elements of an objective pair collide with each other and is decreased when the paring elements of the other pair collide with each other; generate a robot motion for moving the robot along the motion path having the score not lower than a predetermined threshold; measure a drive torque or a current value of a motor when the robot is moved according to the generated robot motion; calculate an index value based on a magnitude of variation of the measured drive torque or current value; and judge as to whether the abnormal clearance exists in the objective pair, based on the index value.

Abstract: A device and method for easily detecting an abnormality of a joint part of a delta-type parallel link robot having a link ball structure, by estimating a friction torque of a ball joint of the robot. A controller of the robot has: a control section configured to control the motion of the robot; a torque measurement section configured to measure or calculate, during the robot is operated, an amount of change in a drive torque, based on a current value of the motor, before and after the robot represents a specified posture where a sign of a relative angular velocity between a ball and a housing of the ball joint is changed; and a judgment section configured to judge that, when the measured amount of change in the drive torque exceeds a predetermined threshold, a friction state of the ball joint corresponding to the motor is abnormal.
