摘要： An automatic welding machine includes a link actuator in which a distal end side link hub is coupled to a proximal end side link hub via three or more link mechanisms and the position of the distal end side link hub relative to the proximal end side link hub can be arbitrarily changed. The automatic welding machine is provided with one or more linear motion actuators configured to cause the proximal end side link hub of the link actuator to advance/retract relative to a mount along respective axes, and a welding torch is mounted on the distal end side link hub. The automatic welding machine further includes a movement mechanism on which peripheral devices connected to the welding torch via cables are mounted so as to be movable in one or more axial directions.

摘要： In this link actuation device, arms of a plurality of link mechanisms are driven to be rotated by actuators, whereby the posture of a distal end side link hub is changed. A divided section setter divides a trajectory on a work surface on which an end effector works, into a plurality of sections at pass points and sets the sections. An arm rotation speed calculator calculates a rotation speed at which each arm performs constant speed rotation in each section on the basis of: a time period of movement in the section which is determined from a target moving speed and the distance of the section; and a rotation-angular movement amount of the arm in the section. A posture change controller performs positioning control on each actuator so as to cause its corresponding arm to continuously rotate at the corresponding rotation speed without acceleration/deceleration.

摘要： This secondary battery degradation determination device includes: a plurality of voltage sensors connected to the respective batteries; a measurement current application device configured to apply measurement current containing an AC component, to each battery group; and a controller. Each voltage sensor is provided with a sensor-specific wireless communicator configured to wirelessly transmit a measurement value of voltage of the AC component. The controller receives the measurement value transmitted by each sensor-specific wireless communicator, calculates an internal resistance of each battery by use of the measurement value, and determines degradation of the battery on the basis of the internal resistance.

摘要： A work apparatus includes a parallel link mechanism, a position control actuator, a linear motion mechanism, and a rotating mechanism. The parallel link mechanism includes three or more link mechanisms that couple a distal end side link hub to a proximal end side link hub such that a position of the distal end side link hub can be changed relative to the proximal end side link hub. The position control actuator operates the parallel link mechanism. The linear motion mechanism moves a working body in an axial direction orthogonal to a central axis of the proximal end side link hub. The rotating mechanism is mounted on the distal end side link hub and rotates a work object about a rotation center axis parallel to a movement direction of the linear motion mechanism when the central axis and a central axis are on the same line.

摘要： A link actuator includes a proximal end side link hub, a distal end side link hub, and link mechanisms which connect the distal end side link hub to the proximal end side link hub. Each of the link mechanisms includes a proximal side end link member, a distal side end link member, and an intermediate link member. Each of the proximal end side link hub and the distal end side link hub is provided with a through-hole which allows an origin positioning shaft to be inserted therethrough. The distal end posture of the link actuator is set to a specified posture by inserting the origin positioning shaft through the through-holes. An amount of operation of actuators in a state where preload is applied to the link actuator is set as a position of an origin of the actuator.
