Patent ID: 7056185

Claim:
A wireless-remote-controlled round profile axle-like rover responsive to control signals from a remote transmitter unit, comprising: a) a pair of ground engaging wheels all having a common central axis of rotation, each of said wheels being omnidirectional and comprising a hub rotatable about said central axis, said hub having a group of peripheral circumrotatory ground-contact elements circumferentially disposed thereof, each of said peripheral elements having a respective spin axis independent in relation to said central axis and each of said peripheral elements being fully rotatable about its own respective said spin axis, said group of peripheral elements defining a substantially circular ground-contact boundary about said central axis on each of said wheels, and b) a wireless remote controlled wheel drive engaging said hub and engaging said group of peripheral elements on each of said wheels and selectively distributing rotational energies among said hub and said group of peripheral elements respectively on each said wheels; whereby said rover substantially resembles a single two-wheeled axle that can rollably careen unobstructed on a ground surface at a speed substantially orthogonal to said central axis of rotation, as well as steer by distribution of opposing rotational energies to each of said hubs, and propel linearly along said central axis by distribution of uniform rotational energies to said groups of peripheral elements of said wheels.
