Abstract: 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 resin containing a continuous 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 in accordance with engagement between a recess provided in one of the main body and the attachment interface and a protrusion provided in the other one of the main body and the attachment interface.

Abstract: A rotary axis module includes an actuator that includes a first member and a second member, the actuator relatively driving the second member so as to rotate about a predetermined axis with respect to the first member, a DC power source, and a switch. The actuator includes a brake that is releasable by supplying a DC voltage. A first brake circuit that is connected to a control device that controls the actuator, and a second brake circuit that is provided in parallel with the first brake circuit and connected to the DC power source via the switch, are connected to the brake.

Abstract: A robot including: two link members with longitudinal axes that are coupled such that the link members are able to relatively rotate about an axial line; and a sensor that detects a force around the axial line acting between the link members due to an object pinched between the link members, in which the robot has such a shape that a width dimension in a direction along a plane of a cross-sectional surface of at least one of the link members, which perpendicularly intersects the axial line, on at least one sides from the longitudinal axes that intersect the axial line continuously spread from at least midway positions of the at least one of the link members in the direction of the longitudinal axes toward the axial line, respectively.

Abstract: A manufacturing apparatus includes an arm main body with a long tubular or columnar shape having a uniform lateral cross-section, and attachment interface parts fixed to both sides of the arm main body and attached to another member. The apparatus includes: a pair of fixing parts supporting a part of each of the attachment interface parts and each end of the arm main body and each including a material filling space at least near a joint part between each of the attachment interface parts and the arm main body; a slide mechanism capable of adjusting a distance between the two fixing parts along a longitudinal axis of the arm main body by moving at least one of the fixing parts; and a material injection part injecting a molten material into the space so as to joint each of the attachment interface parts to each end of the arm main body.

Abstract: An arm-shaped structure includes a pipe-shaped main body and a metallic 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 casting. 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 in accordance with engagement between a recess provided in one of the main body and the attachment interface and a protrusion provided in the other one of the main body and the attachment interface.
