Claim Text:
1. A transmission assembly for an electric motor of a remote vehicle, the transmission assembly comprising: an external housing portion that is movable along an axial direction of an output shaft of the electric motor between first and second axial positions at any time independent of a load on or a speed of the electric motor, wherein the transmission assembly is in a first higher torque lower speed output operational state when the housing portion is in the first axial position, and wherein the transmission assembly is in a second lower torque higher speed output operational state when the housing portion is in the second axial position; a shift actuator mechanism coupled to the electric motor, a sun gear coupled to the output shaft of the motor; a ring gear assembly coupled to a shift coupler, the shift coupler being configured to engage via the shift actuator mechanism; a non-positive clutch configured to absorb energy of a shifting process, comprising: the transmission assembly being configured to be stable within the first and second operational states, requiring no energy to maintain the first or second operational state, and the transmission assembly being configured not to fail when switching between the first and second operational states and to shift between the first and second operational states within a fraction of its assembly time constant because the transmission assembly passes through a neutral operational state quickly when switching between the first and second operational states.
