摘要:
A cable laying structure for a robot, which does not interfere with external devices in a periphery of a forearm. Camera (or force sensor) and hand control cables and motor control cables CB are drawn into a robot mechanism through a connection panel of a base of a robot main body. While allowing the motor control cables to sequentially diverge, the control cables CB are arranged in a robot arm along an upper arm portion and guided to the forearm. The control cables CB are introduced into the forearm with a shield and a sheath removed, and clamped at an appropriate position. After reaching an end effector-mounting face, the control cables CB are connected to a camera (or force sensor) C/S and a hand. The forearm is formed of conductive material and grounded on the base of the robot main body so as to have the same electric potential as the base by using means such as an earth cable or the like, and therefore the forearm is utilized in replacement of the shield.

A system for performing minimally invasive cardiac procedures. The system includes a pair of surgical instruments that are coupled to a pair of robotic arms. The instruments have end effectors that can be manipulated to hold and suture tissue. The robotic arms are coupled to a pair of master handles by a controller. The handles can be moved by the surgeon to produce a corresponding movement of the end effectors. The movement of the handles is scaled so that the end effectors have a corresponding movement that is different, typically smaller, than the movement performed by the hands of the surgeon. The scale factor is adjustable so that the surgeon can control the resolution of the end effector movement. The movement of the end effector can be controlled by an input button, so that the end effector only moves when the button is depressed by the surgeon. The input button allows the surgeon to adjust the position of the handles without moving the end effector, so that the handles can be moved to a more comfortable position. The system may also have a robotically controlled endoscope which allows the surgeon to remotely view the surgical site. A cardiac procedure can be performed by making small incisions in the patient's skin and inserting the instruments and endoscope into the patient. The surgeon manipulates the handles and moves the end effectors to perform a cardiac procedure such as a coronary artery bypass graft.

A linear guide comprises a support element and a carriage sliding on the support element. The carriage has two hollow cylinders sliding on an air bearing on the support element and a body arranged between them. The support element and the two hollow cylinders of the carriage are separated by a gap to which compressed air can be applied. A linear motor formed from a u-shaped stator and an armature is foreseen as drive mechanism for the carriage. During operation, heat dissipation occurs in the armature which heats the carriage. In order to maintain changes in the thickness of the gap within predetermined limits, the support element and/or those parts of the carriage whose temperature influence the thickness of the gap are heated to a predetermined temperature.

A welding robot for spot welding is disclosed. The welding robot is capable of grinding electrode tips promptly and clearly. The welding robot 1 includes a servo gun 5 provided at a front end of a multi-joint arm 2, in which a pair of electrode tips for the spot welding are installed, and a control unit 3 for controlling a servo motor 6 of the servo gun in a welding process or a grinding process of the electrode tips. A dresser 18 for grinding the pair of the electrode tips includes a servo motor 27 for rotating a grinding cutter 30. The control unit 3 controls the servo motor 27 of the dresser and controls the servo motor 6 of the servo gun in order to adjust a pressure of the pair of the electrode tips installed in the servo gun with respect to the cutter. In a finishing grinding process of the electrode tips, the speed of revolution of the cutter is increased and the pressure applied to the cutter is reduced relative to the speed and pressure applied in a rough finishing process.

A buckling arm robot for machining workpieces with laser radiation has at least a first axis, a second axis, a third axis, a fourth axis, and a fifth axis. A laser device is arranged in the second axis and configured to emit a laser beam. The laser beam emitted by the laser device is guided within the third, fourth, and fifth axes before striking a workpiece to be machined.

A pallet changer is rotatable around a pin which releasably engages a shop floor. A pneumatic load module assembly creates a cushion of air which supports the pallet changer for manual rotation. The pin can be released from the floor to allow linear horizontal movement of the pallet changer or the cushion of air when it is necessary to repair, refurbish or replace equipment adjacent the pallet changer.

The invention concerns a kinematic device for supporting and programmably moving a terminal element. The platform (11) bearing the terminal element (12) is linked by four swivel joints (9) and (10) with two legs each consisting of two support rods (7) or (8) forming deformable parallelograms mounted each on slides (3) or (4) mobile in the x direction. The pivot plate (29) articulated on the platform (11) about the hinge pin (30) is controlled by the control rods (27), controlling pivoting (14) and lateral displacement (18) connected respectively by the swivel joints (26, 13 and 17) to the slides (3, 12 and 26). It consists in a parallel kinematics with four degrees of freedom, namely three translational and one rotational whereof the angle can be greater than 120null.

Magnetic forces are used as a controlled actuation mechanism to move and position objects of interest. In one embodiment, a first spherical surface has at least one magnetic positioner attached. A second spherical surface is positioned to move relative to the first spherical surface. A plurality of controlled electromagnets are spaced about the second spherical surface. Control logic energizes at least one of the controlled electromagnets to create magnetic interaction with at least one magnetic positioner to move the first spherical surface relative to the second spherical surface.

New artificial muscles and actuators, that are operated by hydrogen gas as working fluid stored interstitially in metal hydrides as a hydrogen sponge. These artificial muscles and actuators are operated both electrically and thermally. The artificial muscles and actuators have fast response, are compact/light-weight, are noiseless, and produce high-power density. They can be used for biomedical, space, defense, micro-machines, and industrial applications.
