Title:
SELF-BALANCING AND POWER-ASSISTED PAYLOAD CARRYING VEHICLES USING OPERATOR-APPLIED FORCE SENSING
Document Type and Number:
WIPO Patent Application WO/2018/118856
Kind Code:
A3
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.
