Abstract: A joint structure of a robot for moving an assembly 51 to be connected to a robot link with respect to the robot link, the joint structure includes a first motor 10 for causing the assembly a longitudinal swing motion, a second motor 20 for causing the assembly a lateral swing motion, and a third motor 30 for causing the assembly a rotary motion, wherein the first motor 10 and the second motor 20 are disposed so that the output shaft of the first motor 10 and the output shaft of the second motor 20 are in parallel with each other and are orthogonal to the robot link, and the third motor 30 is disposed so that the output shaft of the third motor 30 is shifted with respect to the central axis of the rotary motion of the assembly 51.

Abstract: A robot hand apparatus (1) includes four of finger mechanisms (20) each elongates from a base (10), a motor (30) actuating each finger mechanism (20), four of rotation rollers (50) each connects with corresponding finger mechanism (20) for actuating each finger mechanism (20), and a power transmission mechanism (60) transmitting a power from the motor (30) to each rotation roller (50) at different timing.

Abstract: A robot hand apparatus (1) includes a base (2); a motor (M); a first-link (10) supported by the base (2) while allowing the rotation around a first axis (S1), which is in parallel to an actuation axis (G) of the motor (M) and is positioned apart from the actuation axis (G), the first-link (10) has a first guide path (11b) movably supporting a control axis (42); a second link (20) which connects with the actuation axis (G) and supports the control axis (42), and moves the control axis (42) within the first guide path (11b) in accordance with the rotation of the actuation axis (G); and a finger link (F1) supported by the first link (10) while allowing the rotation around a second axis; and the finger link (F1) directly or indirectly links with the control axis (42) and is rotated by the actuation of the control axis (42).
