  • Magnetic rotational hardstop for robot
    Patent number: 8757345
    Abstract: Rotational hardstop assemblies that provide greater than 360 degrees of non-continuous rotation for rotating mechanisms are provided. In certain embodiments, an assembly is used to provide 630 or more degrees of rotation for the shoulder axis of a robot, such as a wafer transfer robot. The rotational hardstop assemblies include opposing magnets as springs. According to various embodiments, the opposing magnets provide non-contact engagement and produce no contact noise nor have any wear over time. The rotational hardstop assemblies provide the ability to location from either direction of rotation of a robot cylindrical coordinate system.
