Abstract: An end effector connectable to a robot arm for peeling off release paper includes a housing including a guide groove having a start position S, an intermediate position M, and an end position E and a rotary unit including a needle and a first support movable along the guide groove. Assume that a line segment connecting the start position S and the intermediate position M is defined as a line segment SM, a line segment connecting intermediate the position M and the end position E is defined as a line segment ME, an angle formed between the line segment SM and a horizontal direction when the end effector is placed on a floor surface is defined as ?1, and an angle formed between the line segment SM and the line segment ME is defined as ?2, ?1<?2<?1+180° is satisfied.

Abstract: An end effector connectable to a robot arm includes a camera, a support member that includes a marker and supports a workpiece, and a brush that performs coating on the workpiece. The camera is arranged at a position allowing the camera to capture a brush tip of the brush and the marker simultaneously.
