Abstract: A robot arm includes a robot hand including a hand base to which first and second finger connection portions are connected, and a finger moving portion to move the first and second finger connection portions with respect to the hand base such that a distance between a first finger and a third finger increases or decreases. A rotation axis rotating the hand base passes through a midpoint between fingertips of the first finger and the third finger while the first finger and the third finger are perpendicular to the hand base. the robot arm includes a forearm and a wrist joint to connect the robot hand to the forearm rotatably with two rotational degrees of freedom or one rotational degree of freedom. The forearm is rotatable around a forearm rotation axis that passes through the forearm and is the rotation axis that allows the hand base to be rotated.

Abstract: A robot hand operation device through which an operator inputs an operation instruction to move a robot hand including at least three fingers includes: a main body portion held by the operator; and joysticks each being corresponded with each of the fingers of the robot hand to be operated and provided in the main body portion in a number that is the same as that of the fingers. When the operator operates each of the joysticks, the operation instruction to move the finger corresponded with the each of the joysticks is inputted, and when the operator does not operate each of the joysticks, the operation instruction to move the finger corresponded with the each of the joysticks is not inputted.

Abstract: A robot arm operation device is mounted on an upper arm, a forearm, and a hand of an operator and through which the operator inputs, by moving the robot arm operation device, an operation instruction to operate a robot arm to a control calculation device that controls the robot arm. The robot arm operation device includes: a shoulder joint angle measurement part to measure a shoulder joint measurement angle being an angle at which an upper arm structure is connected to an arm connection structure at a shoulder measurement joint; an elbow joint angle measurement part to measure an elbow joint measurement angle being an angle at which a forearm structure is connected to the upper arm structure; and a wrist joint angle measurement part to measure a wrist joint measurement angle being an angle at which a hand structure is connected to the forearm structure.

Abstract: A rotation connecting mechanism includes: a joint that connects a second member rotatably to a first member with three rotational degrees of freedom; a first link and a third link in each of which one end is attached rotatably to second member with at least two rotational degrees of freedom while the other end is attached rotatably to first member with at least two rotational degrees of freedom, each of first link and third link having a variable length and five rotational degrees of freedom; a second link in which one end is attached rotatably to first link with at least two rotational degrees of freedom while the other end is attached rotatably to first member with at least two rotational degrees of freedom, second link having a variable length and five rotational degrees of freedom; and motors that generate force changing lengths of the three links.

Abstract: A parallel link device whose height can be reduced particularly when a movable-side member is brought closer to a fixed-side member, and in which an amount of stroke of the movable-side member can be increased. Specifically, the parallel link device includes a fixed-side member, a movable-side member, six links, and slide mechanisms. Each of the six links has one end connected to the movable-side member with at least two rotational degrees of freedom, and the other end connected to the fixed-side member with at least two rotational degrees of freedom. A connection point of the other end and the fixed-side member is movable with respect to the fixed-side member. Each of the six links has five rotational degrees of freedom and a predetermined length. Each of the slide mechanisms is provided on the fixed-side member and holds the other end of the link movable within a predetermined range.
