Motorized fitness wheel

Abstract

Systems and methods disclosed herein concern a motorized fitness wheel. The fitness wheel includes a wheel that rotates about an axle with two handles that extend outward from respective sides of the wheel along the rotational axis. In use, the user grasps the handles with their hands and rolls the wheel back and forth along the floor. A motor is configured to apply a torque to the wheel in either forward or backward direction to apply resistance or assistance and enhance the exercise. A position sensor feeds positional information of the motor to a microcontroller. Based on the positional information, the microcontroller dynamically controls the output torque of the motor as a function of one or more torque trajectories. The torque trajectories define the output torque of the motor over a cycle of the exercise as a function a spatial variable (e.g., wheel position) and/or time.
