A robot arm (50) of the present invention includes, as a direct acting extensible/retractable joint (J3), an arm section (2) constituted by an upper structure group (20) and a lower structure group (21). Groups (20) and (21), having an arrangement in which structures are connected in series, partially engage so as to form a direct rigid combined structure, and are separated so as to release the rigid structure. An arm length can be adjusted arbitrarily. Section (2) can have a plane surface having no gap to prevent entry of a finger/dust. Separation of Groups (20) and (21) allows an upper structure (22) and a lower structure (23) to rotate around their rotational axes, to realize compact storage inside a robot arm supporting member (1). It is thus possible to prevent significantly entry of a finger/dust, and provide a compact direct acting extensible and retractable arm mechanism. |

A tentacle mechanism comprising an elongate helicoid stage of windings having multiple through bores formed therethrough which carry control lines for controlling the shape of stages of the helicoid tentacle. An actuator and motor control the control lines and additional cables positioned in other sets of through bores can change the length and shape of the tentacle as well as desired spatial attitude. Embodiments of the tentacle carry end effectors at the distal end-effector actuation cables couple the end-effectors to actuator and motor. |

A multi-joint arm mechanism includes an arm supporting member a first, second and third joints. The third joint has a linear extension and retraction axis. The third joint includes flat-shaped first structures bendably coupled to one another, second structures having a C-shaped section and bendably coupled to one another, a supporting member supporting the stiffened first and second structures, and a drive member sending and drawing the stiffened first and second structures. The first and the second structures are linearly stiffened by being in contact with each other and return to a bent state by being separated from each other. The second structures are bent toward the bottom parts and conveyed into the arm supporting member. The first structures are bent in a same direction as the second structures and conveyed into the arm supporting member. The first structures are stored in the arm supporting member along the second structures. |

The invention provides an articulating mechanism useful, for example, for remote manipulation of various surgical instruments and diagnostic tools within, or to, regions of the body. Movement of segments at the proximal end of the mechanism results in a corresponding, relative movement of segments at the distal end of the mechanism. The proximal and distal segments are connected by a set of cables in such a fashion that each proximal segment forms a discrete pair with a distal segment. This configuration allows each segment pair to move independently of one another and also permits the articulating mechanism to undergo complex movements and adopt complex configurations. The articulating mechanisms may also be combined in such a way to remotely mimic finger movements for manipulation of an object or body tissue. |

A bend sensor is used to determine force applied to a robotic arm. The force may be an external force applied to the arm, an internal actuation force, or both. In some aspects, a stiffening element is used to restore the arm to a minimum kinematic energy state. In other aspects, the stiffening element is eliminated, and the arm is fully actuated. |

The articulating boom includes an actuator, a multi-directional flexible arm having a first end region attached to the actuator, and a cable extending through the flexible arm. The cable has one end region connected to the actuator and another end region connected to a preload tensioning mechanism. The actuator is operable to tighten and loosen the cable, and the preload tensioning mechanism maintains an amount of tension in the cable when the actuator loosens the cable. The system further includes a surgical instrument-supporting member that is attached to a second end region of the flexible arm and is configured to releasably retain a surgical instrument. |

A linear-motion telescopic mechanism according to the present invention includes a plurality of block members (22) by which an arbitrary arm length is achieved in such a manner that the plurality of block member (22) are rigidly connected to each other so as to elongate a linear-motion telescopic joint (J3). On the other hand, by separating the plurality of block members (22) one by one from a rigid alignment of the plurality of block members (22), the linear-motion telescopic joint (J3) is contracted. The block members (22) unfixed from the rigid alignment are still serially connected but not in a rigid manner. That is, the block members (22) thus unfixed can be flexed in any directions, and therefore can be housed inside a support member (1) in a compact manner. This arrangement can provide a linear-motion telescopic mechanism (i) which enhances safety by eliminating such a risk, inevitable for a typical robot arm having an elbow joint, that an object around the robot arm gets caught between arm sections when the elbow joint is closed, and (ii) which can reduce a space to be occupied by the robot arm. |
