Robot and robot system

Abstract

To provide a robot and a robot system that allow for downsizing an intermediate pulley.SOLUTION: A robot comprises: a first pulley fixed to a rotation shaft of a motor; a second pulley fixed to a spline nut; an intermediate pulley that is supported by a support member through a bearing, and that rotates around a fourth rotation axis with respect to a second arm; a first belt wound around the first pulley and the intermediate pulley; and a second belt wound around the intermediate pulley and the second pulley. The intermediate pulley has a first intermediate pulley around which the first belt is wound, a second intermediate pulley around which the second belt is wound, and a shaft part connecting the first intermediate pulley to the second intermediate pulley. The first intermediate pulley has a recessed part opening to a surface on the second intermediate pulley side, into which the shaft part is inserted, where at least a portion of the bearing is positioned in the recessed part. In a planar view from a direction that is orthogonal to the fourth rotation axis, the bearing overlaps with the first belt.SELECTED DRAWING: Figure 7
