An actuator according to an aspect of the present invention includes: a driving body including a plurality of conductive grains, a chamber configured to confine the plurality of conductive grains, and two or more electrodes disposed on a surface of the chamber, and a controller configured to obtain, through the two or more electrodes, a change in an electric signal, in response to a load applied to the chamber, and to adjust the load applied to the chamber based on the change in the electric signal.

For the purpose of achieving a further reduction in weight while maintaining strength and of reducing the manufacturing cost, the present invention provides a robot arm including: a long cylindrical arm body; and mounting interface portions that are fixed at both sides of the arm body and that are used to mount the robot arm to another member. At least sections of outer surfaces of the arm body and the mounting interface portions are formed of a resin. A first part that has one of the mounting interface portions and a section of the arm body and a second part that has the other one of the mounting interface portions and a section of the arm body are joined to each other.

An arm-shaped structure includes a pipe-shaped main body and an attachment interface joined to at least one end of the main body and securable to another component. At least a portion of the main body and the attachment interface is formed by injection-molding resin containing a discontinuous reinforcement fiber. The main body and the attachment interface are joined to each other in a state where relative movement along a longitudinal axis of the main body and around the longitudinal axis is prevented by an uneven section formed by injection-molding.

A non-Cartesian coordinate positioning machine that includes an extendable leg assembly for positioning a component such as a measurement probe within a working volume of the machine. The extendable leg assembly includes a first member and a second member which move relative to one another when the extendable leg assembly changes length. The first member including an axial arrangement of magnets forming part of a linear motor for extending and retracting the extendable leg assembly, and at least one resilient member for absorbing at least some of any axial thermal expansion or contraction of the magnets in use.

A linear motion device includes: a linear motion mechanism having: a beam elongated in one horizontal direction; a guide member disposed in the beam to extend in the one direction; a moving member disposed to be movable along the guide member; and a moving mechanism that moves the moving member. The beam includes a metallic tubular body formed with an opening portion penetrating the metallic tubular body in the one direction and a tubular reinforcing portion formed of a carbon fiber reinforced plastic and formed in close contact with an inner surface of the metallic tubular body.

The present invention relates to a robotic arm (10) with five or more degrees of freedom of motion and comprising substantially load-bearing polymeric parts.

The present disclosure relates to a manipulator arm, a manipulator and a carrying device. The manipulator arm includes at least one arm body for carrying a to-be-carried object, wherein the arm body is provided with a suction plate for sucking the to-be-carried object, and the suction plate is provided with a plurality of vacuum suction holes.

Provided is a robot including at least one joint, and at least two links and coupled with each other by the joint. At least one of the links and includes an inner layer made of carbon fiber reinforced plastic, and an outer layer made of elastic material and covering an outer peripheral surface of at least part of the inner layer in a longitudinal direction over an entire circumference, the layers being integrally stacked.

The following abstract for invention refers to the development of an auxiliary robot with artificial intelligence, performing several tasks and managing teams, said robot (10) having movable head (1), rotating torso (30), movable arms (11 and 12), a hinged hand (18) and hand having a laser system (19), the torso (30) being rotatable over a base (38), being able of interacting with the user (43) by means of voice commands (44), and can also receive settings, personalization and manual control (45) by means of a Web interface (46), by means of a computer (47), wherein said computer can request data (48) and synchronize the robot (10), which can be controlled by means of wireless connection by some application (APPs) to carry out interactions (49).
