APPARATUS AND METHODS FOR A SPHERICAL ASSEMBLY

This disclosure relates generally to vehicles propulsion based on the use of natural gravitational forces and, in some instances, the use of electric motor control. In some examples, a spherical assembly includes a spherical encasing a first motor connected to a first weight, a second motor connected to a second weight, and a power generator configured to supply power to the first motor and to the second motor. The spherical assembly may also include a controller that is configured to cause the first motor to rotate the first weight in a first direction at a first rotational speed and the second motor to rotate the second weight in a second direction at a second rotational speed based on the rotational speed of the spherical assembly. The controller may also be configured to cause the power generator to generate power for the first motor and the second motor.
