Abstract
A motorized movement device includes a frame, first and second wheels connected to the frame, and first and second motors connected respectively to the first and second wheels that are commandable by respective command signals. The motorized device also includes an inertial measuring unit configured to detect the longitudinal acceleration, pitch angular speed, and yaw angular speed of the movement device and for providing signals representative of the same. The motorized device also includes sensors for detecting speeds of the wheels and configured to provide signals representative thereof. The motorized device further includes a control unit comprising a module for estimating the slope, and longitudinal thrust exerted by a user to the device, yaw torque applied by the user. The control unit also includes a module for compensating the slope, a thrust amplifying module, a yaw torque amplifying module, and a torque allocating module.
