In an exemplary embodiment, magnetic system comprises a robotic arm and a magnetic base. The robotic arm comprises a pivot joint allowing the robotic arm to move in at least one direction. The magnetic base is coupled to the robotic arm and supports the robotic arm. The magnetic base comprises a magnetic coupler and a wheel. The magnetic coupler comprises a workpiece contact interface and a magnet assembly configurable between off and on states. The off state produces a first magnetic field at the workpiece contact interface that is less than a second magnetic field produced at the workpiece contact interface when in the on state. The wheel rotates about an axis and supports the magnetic base to permit a movement of the magnetic system.Type: ApplicationFiled: November 5, 2019Publication date: March 10, 2022Inventors: David H.
