Patent attributes
A robot includes a robot main body including an A-arm which rotates around an A-rotation axis, a B-arm which is cantilevered off the A-arm and rotates around a B-rotation axis, and a C-arm which is connected to the B-arm, to which an end effector is attached, and which rotates around a C-rotation axis. The A-arm includes a first restriction that is not exposed to the outside of the robot main body. The B-arm includes a clamp which is connected to the end effector and restricts a position of a flexible wiring or pipe, a second restriction that is not exposed to the outside of the robot main body and contacts on the first restriction, and a hole through which the wiring or the pipe is inserted. The C-arm includes a through-hole which penetrates the C-arm along the axial direction of the C-rotation axis.
