A transfer robot includes a plurality of hands, a plurality of hand drive motors, and an arm. The plurality of hands are capable of holding a transfer target object, and pivot individually around a pivoting axis. The plurality of hand drive motors are arranged in a direction following the pivoting axis, such that a motor axis to which the plurality of hands are each connected becomes concentric with the pivoting axis, and directly drive the plurality of hands, respectively. The arm includes therein the plurality of hand drive motors.

Transfer robot and robot system

A conveyance system includes a conveyance chamber including a second side wall opposite to a first side wall in a depth direction of the conveyance chamber. A robot is disposed in the conveyance chamber. The robot includes a body, a first arm, a second aim, and a hand. The body is disposed between the second side wall and a reference position in the depth direction. A second leading end of the second arm is positioned between a restricted position and the reference position in the depth direction when a first inter-axis direction and a second inter-axis direction are substantially perpendicular to the first side wall. A controller is connected to the robot to control the robot to limit entrance into an area between the first side wall and the restricted position in the depth direction.
