Abstract
A spherical modular autonomous robotic traveler (SMART) is provided for rolling along a surface from a first position to a second position. The SMART includes an outer spherical shell; an inner spherical chamber disposed within the outer shell; a plurality of weight-shifters arranged within the inner chamber; and a controller therein. The chamber maintains its orientation relative to the surface by a gyroscopically homing stabilizer. Each weight-shifter includes a mass disposed in a default position, and movable to an active position in response to activation. The controller selectively activates a weight-shifter among the plurality to shift the mass from the default position to the active position. The outer shell rolls in a direction that corresponds to the weight-shifter activated by the controller. The weight-shifters for the SMART employ pneumatic actuation as a spherical pneumatic actuated robotic commuter (SPARC). Each weight-shifter in the SPARC includes a conduit containing a liquid armature and a pressure source with valves activated by the controller, with the conduits arranged in a cruciform configuration.
