Abstract
A magnetic on-off robotic attachment device (MOORAD) () is used to make a number of systems, such as a mobile apparatus ('), a belt mechanism () and a sensor device (). The MOORAD allows the respective system to be removably magnetically attached to a ferromagnetic structure/object (A-B,A′-B′,). Each MOORAD generally includes a dipole magnet (A-B,) movable relative to first and second ferromagnetic portions (A-D,) that are separated by corresponding magnetically insulating portions (A-C,) so as to change that MOORAD between off and on states.
