Abstract: A conveying system includes at least one guide unit and a carrier. The guide unit includes a traveling surface, at least one guide rail, and a magnetic member formed of a soft magnetic material and including a plurality of salient poles aligned along a conveying path. The carrier includes at least one roller coming in contact with the guide rail from a side direction, at least one wheel coming in contact with the traveling surface, and a plurality of coils provided to overlap with the magnetic member in plan view, and configured to generate thrust along the conveying path and attraction toward the magnetic member by generating a moving magnetic field acting on the magnetic member in accordance with supply of power.

Abstract: 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.
