Abstract:
1. A moving device to roll across a surface and comprising: a stator comprising a stator body and a plurality of electromagnets carried thereby; a rotor rotatably mounted within said stator and comprising a rotor body and a plurality of permanent magnets carried thereby; and a plurality of carbon nanotube fibrils protruding from an outer surface of said rotor body and having free-ends configured to establish adhesion to the surface by inter-molecular Van der Waals forces; said plurality of permanent magnets cooperating with said plurality of electromagnets to define a brushless motor so that supplying electrical power to said stator causes rotation of said rotor to thereby roll the moving device across the surface while said plurality of carbon nanotube fibrils establishes adhesion to the surface; wherein said plurality of carbon nanotube fibrils comprise alternating rows of carbon nanotube fibrils inclined at opposing, intersecting angles from orthogonal to the outer surface of the rotor.
