Abstract
A transfer robot includes a supporting part, a moving part, a magnet unit, and a coil. The moving part is supported by the supporting part and movable along a predetermined travel path. The moving part is provided with a hand for carrying a workpiece. The magnet unit is disposed at the supporting part and extends longitudinally along the travel path. The magnetic unit generates magnetic flux that is at least partially perpendicular to the travel path. The coil is disposed at the moving part and intersects the magnetic flux. The magnetic flux varies or is different at positions along the travel path.
