  • Self-balancing and power-assisted payload carrying vehicles using operator-applied force sensing
    Patent number: 10889312
    Abstract: A method of operating a payload-carrying vehicle having two laterally disposed wheels positioned along a central axis is described. The method includes measuring a force applied by a user to the hand truck, where the measured force comprising a direction and a magnitude, and providing torque to each wheel to cause each wheel to rotate in a respective direction as a function of the measured magnitude and direction. The amount of torque provided to each wheel in response to the force from the user is such that the magnitude of measured force applied by the user is not greater than a predetermined threshold value.

  • Control of a power-assisted payload carrying vehicle using operator-applied force sensing
    Patent number: 10858027
    Abstract: In a method of operating a payload-carrying vehicle having a system configured to provide torque to ground contacting elements, the method includes, repeatedly measuring a force applied by a user to the vehicle; determining a direction and a magnitude of the measured force; determining a respective amount of torque to apply to each of the ground contacting elements as a function of the determined direction and magnitude; and providing the respective determined amount of torque to each of the ground contacting elements.
