US Patent 12059812 Rotating switch sensor for a robotic system

A sensor system includes a first member that extends along a rotational axis and has a surface disposed circumferentially about the rotational axis. A conductive element is disposed on the surface of the first member and disposed about the rotational axis. A second member extends along the rotational axis. A rotational position between the first member and the second member is adjustable. A target is mounted to and rotatable with the second member and is movable relative to the second member between first and second positions. The target is spaced apart from the conductive element in both the first and second positions and is spaced further from the conductive element in the second position compared to the first position. The conductive element detects a change in movement of the target from the first position to the second position for any rotational position between the first member and the second member.
