Abstract: A flywheel system comprises a flywheel rotor comprising a rotor disc and a rotor shaft and has a longitudinal axis extending centrally through the rotor disc and the rotor shaft. The system further comprises a journal assembly configured to facilitate rotation of the flywheel rotor. The journal assembly comprises a sleeve having an aperture extending therethrough from a first end to a second, opposite end, a rod at least partially disposed within the aperture of the sleeve, and a nut coupled to a portion of the rod. The rod has a length greater than the sleeve such that a portion of the rod extends axially beyond the first end of the sleeve. A method of forming the flywheel comprises coupling the rod to the rotor shaft and pulling the second end of the rod to tension the rod. The nut maintains the tension in the rod when coupled thereto.

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. For the spherical electromagnetically initiated traveling excursor (SEMITE), each weight-shifter includes a channel containing an armature and an electromagnet activated by the controller. For the symmetrical configuration, the channel is oriented from bottom periphery to lateral radial periphery of the inner chamber. The electromagnet is disposed proximal to the channel at the lateral radial periphery. The armature travels from the bottom periphery within the channel to the lateral radial periphery upon activation of the electromagnet.

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.

Abstract: The embodiments herein provide a system and method to convert gravity into continuous rotational motion of a wheel through non-compressible liquid. The system comprises a wheel. Several cylinders and pistons are arranged and equally spaced on the wheel. The cylinders arranged diagonally opposite to each other are connected through a pipe to provide a pathway for the non-compressible fluid. A folding bag is provided in each cylinder and filled with the non-compressible fluid. The folding bags arranged diagonally opposite to each other are connected through connecting pipes. The non-compressible liquid flows into the folding bags based on the motion of the wheel. Each folding bag expands and folds depending on the amount of fluid in the folding bag. The fluid motion maintains the imbalance of the wheel's weight and the wheel sustains the rotational motion.
