The manipulator includes a manipulator link, a second joint coupled to the manipulator link distal from the first joint, an elevation linkage coupled to the manipulator link at the second joint, a wrist coupled to the elevation linkage distal from the second joint, and an end effector coupled to the wrist. The end effector can change elevation via the elevation link without changing orientation.

An external gear includes a body, external teeth, a diaphragm, and a strain gauge. The diaphragm extends in a direction intersecting with an axial direction on another side in of the body the axial direction. The strain gauge is on at least one of a surface on one side of the diaphragm in the axial direction and a surface on another side of the diaphragm in the axial direction. The strain gauge is only in a region that is about a half or less of a radial length from one end of the diaphragm in the axial direction to the other end of the diaphragm in the axial direction with a radial midpoint between the one end of the diaphragm in the axial direction and the other end of the diaphragm in the axial direction as a center in a section passing through the central axis.

A system for transporting fiber ends can comprise a fiber supply assembly that supplies fiber along a first axis. A plurality of eyeboards can be positioned along the first axis. Each eyeboard can define a plurality of openings therethrough. Each opening of the plurality of openings can be configured to receive therethrough a fiber from the fiber supply assembly. A track can extend along the first axis. The track can pass proximate to each eyeboard of the at least one eyeboard. A carriage can be movable along the track. The carriage can define at least one fiber attachment element. An actuator can be configured to move the carriage along the track.

Provided is an industrial robot in which a gear for causing a work tool to rotate can easily be retrofitted to a robot without requiring work to adjust backlash. The present invention comprises: a first wrist element that, at the distal end of a front arm of a robot, is capable of rotating about a first axis following the longitudinal direction of the front arm; a second wrist element that, at the first wrist element, is capable of rotating about a second axis intersecting the first axis in a roughly perpendicular manner; a third wrist element that, at the second wrist element, is capable of rotating about a third axis extending from the intersection point of the first and second axes in a direction roughly perpendicular to the direction in which the second axis extends; a first gear that is attached to the third wrist element coaxially with the third axis and that is capable of rotating about the third axis; a second gear that is driven by rotation of the first gear due to meshing with the first gear and that is capable of rotating; and a case secured to the second wrist element. The second gear is attached to the case via a bearing so as to be capable of rotating about a fourth axis positioned at a prescribed distance relative to the third axis.

A self-propelled gripper is installed on a robotic arm. The robotic arm includes a body and a tip axis. The self-propelled gripper includes a housing, a rotation element, a moving element, and at least one claw body. The housing is fixed on the body. The rotation element is disposed in the housing and secured with the tip axis. The moving element is movably disposed in the housing and is connected to the rotation element. The moving element includes at least one slot. The claw body is pivoted on the housing and partially extends in the corresponding slot. When the rotation element rotates along with the tip axis, the rotation element drives the moving element to process a linear motion along a rotation central line so that the claw body pivotally rotates on the housing.

A robot joint structure includes a first robot member, a second robot member, and a speed reducer incorporated in a joint portion that connects the first robot member and the second robot member to each other. The speed reducer includes an external gear, an internal gear that meshes with the external gear, and a fixing member that is provided so as to be non-rotatable relative to the internal gear and is fixed to the first robot member. The fixing member is fixed to the first robot member by bringing an inner peripheral surface of the first robot member and an outer peripheral surface of the fixing member into pressure contact with each other by fastening using a first fastening member. At least a part of an axial range of the first fastening member does not overlap internal teeth of the internal gear when viewed in a radial direction.

A transfer hand of a material transport device for receiving a material from a counterpart device or delivering the material to the counterpart device includes a hand main body, a hand driving motor disposed on one side of the hand main body, a guide configured to move according to the hand driving motor, a pusher disposed on one side of the guide and configured to press the material, and a clamp disposed on the other side of the hand main body and configured to maintain a position of the material, wherein, when the hand driving motor operates, the guide is configured to move, and the pusher and the clamp are configured to interoperate.

A waterjet system in accordance with at least some embodiments includes a carriage, a motion assembly configured to move the carriage horizontally relative to a workpiece, and a cutting head carried by the carriage. The waterjet system can also include a kinematic chain through which the cutting head is operably connected to the carriage. The kinematic chain can include first, second, and third joints rotatably adjustable about different first, second, and third axes, respectively. The carriage and the first and second joints can be configured to move the cutting head along a path relative to the workpiece while the cutting head directs a jet toward the workpiece to form a product. The third joint can be configured to shift a kinematic singularity away from the path to reduce or eliminate delay and corresponding reduced cutting accuracy associated with approaching the kinematic singularity.
