Abstract: A hand includes a hand body in which a predetermined first reference axis is defined, a gripper in which a predetermined second reference axis is defined and which grips a workpiece, and a coupler that couples the gripper to the hand body. The coupler includes at least one of a decentering supporter that supports the gripper such that the second reference axis is capable of being decentered with respect to the first reference axis, or a tilt supporter that supports the gripper such that the second reference axis is capable of being tilted with respect to the first reference axis.

Abstract: A bending mechanism includes: a shaft part; a bendable part linked to the shaft part; a forward end part linked to the bendable part; an operating rod or an operating wire inserted through grooves or holes of the shaft part and the bendable part and having a distal end thereof fixed to the bendable part; and a pressing portion configured to be able to press the operating rod or the operating wire against a fixed portion of the shaft part. The bendable part is configured to be bendable as a result of the operating rod or the operating wire being operated in an extending direction thereof. The operating rod or the operating wire is configured such that, when pressed against the fixed portion of the shaft part by the pressing portion, the operating rod or the operating wire is fixed by friction force.

Abstract: A hand includes a base, two first fingers extending from the base and bendable, and an opening/closing actuator disposed in the base and moves the two first fingers in a predetermined opening/closing direction so that the two first fingers grip a workpiece. Further, there is a bending actuator disposed in the base and causes the two first fingers to bend. Each of the first fingers includes a second part extending from the base and a first part coupled to the second part to be rotatable about a rotation axis parallel to the opening/closing direction. The first part is bendable with respect to the second part. The first part includes a damper that causes the first part to elasticity extend and contract in an extension direction of the first part.

Abstract: A robot hand includes a first finger, a second finger, and a first moving mechanism that brings the first and second fingers close to each other in a predetermined moving direction so that the first and second fingers grip a workpiece. The first moving mechanism includes a first movable pulley, a first wire that has two ends, one of which is connected to the first finger and the other is connected to the second finger, and is wrapped around the first movable pulley, and a first air cylinder that moves the first movable pulley. The first air cylinder moves the first movable pulley so that a tension of the first wire acts on the first and second fingers and to bring the first and second fingers close to each other.

The first gripper 2 includes two first fingers 21 that are opened and closed in a predetermined opening/closing direction. Each of the first fingers 21 includes a first part 22 including a distal end and a second part 23 including a proximal end, and is bent or curved such that the first part 222 moves between an interference position M1 at which an imaginary region X defined by projecting the first part 22 in the opening/closing direction A interferes with the axis E and a non-interference position M2 at which the imaginary region X does not interfere with the axis E.

Abstract: A second hand H2 that couples a first workpiece to a second workpiece, where the first and second workpieces are to be coupled to each other by insertion coupling, includes: a second gripper 5 that grips the first workpiece; a straight-moving actuator 6 that moves the second gripper 5 straight in the direction of a predetermined axis E; and a rotation actuator 7 that rotates the second gripper 5 about the axis E. The second gripper 5 includes three second fingers 51 that grip the first workpiece, and a linkage 52 that opens and closes the three second fingers 51.
