Claim 0:
1. A motorized exercise wheel for performing an exercise having at least one cycle in which a user rolls the wheel along a surface in a forward direction from an approximate resting position to an extended position and then rolls the wheel along the surface in a backward direction from the extended position toward the resting position thus forming an exercise cycle, the motorized exercise wheel comprising:
a wheel assembly including a surface-contacting element, the surface-contacting element being configured to contact the surface and rotate about an axle in either a forward rotational direction or a backward rotational direction and thereby roll along the surface in either the forward or backward direction;
a first and second handle configured to receive each hand of a user, the first and second handle extending outward from respective sides of the wheel assembly;
a motor coupled to the wheel assembly and configured to apply an output torque to the surface-contacting element in either the forward rotational direction or the backward rotational direction;
a microcontroller comprising one or more processors and being configured to control the output torque of the motor;
a first sensor in communication with the microcontroller and useable by the microcontroller to determine a movement variable of the exercise wheel in real-time throughout the exercise cycle, wherein the sensor measures a rotary angle of the motor and wherein the movement variable includes one or more of a position of the exercise wheel, a velocity of the exercise wheel and an acceleration of the exercise wheel;
a non-transitory computer readable storage medium accessible by the microcontroller, wherein the microcontroller is further configured to control the output torque of the motor over the exercise cycle dynamically as a function of the rotary angle, the determined movement variable and one or more torque trajectory parameters, wherein the one or more torque trajectory parameters comprise a torque profile, the torque profile defining a target output torque value of the motor that varies as a function of one or more of the position, the velocity and the acceleration; and
a battery on-board the exercise wheel and configured to power the motor and the microcontroller.
