Spherica weight-shifting integral free-rolling tumbler
First Claim
1. A spherical weight-shifting integral free-rolling tumbler (SWIFT) for moving along a surface in a command direction, said SWIFT comprising:
- a spherical shell having an exterior surface for rolling on the surface and an interior surface for containing an internal volume;
a substantially cubic box within the internal volume, said box comprising six panels being substantially perpendicular to adjacent neighbors, each panel including an outer platform for connecting a weight-shifter, each said weight-shifter having an actuator and a mass, said actuator translating said mass from a default position adjacent associated said panel to an active position adjacent said interior surface; and
a controller within said box for selectively activating said weight-shifter among said panels to translate said mass from said default position to said active position, whereinsaid controller operates a first switch corresponding to panels facing away from the surface, and in combination operates a second switch corresponding to a weight-shifter that approximately faces the command direction to roll said shell along said exterior surface accordingly.

Abstract
A spherical weight-shifting integral free-rolling tumbler (SWIFT) is provided for rolling along a surface in a command direction. The SWIFT includes a spherical shell, a cubic box within the shell held by spars, and a controller. The box has six panels, and each panel connects to a weight-shifter. Each weight-shifter includes an actuator and a movable mass. The controller for selectively activates the weight-shifter among the panels to translate the mass from the default position to the active position. The controller operates a first switch that corresponds to panels facing away from the surface, and in combination operates a second switch that corresponds to a weight-shifter approximately facing the command direction to roll the shell accordingly.
