Abstract
A locomotion device on castors including: at least one castor mechanically connected to a sole to roll along a ground, the castor being mounted to rotate about an axis of rolling parallel to a plane of the sole and also about an axis of rotation perpendicular to the plane of the sole; a controllable electromechanical braking device configured to apply a braking torque to the castor that varies according to a braking command received; an inertial unit configured to measure a physical parameter indicative of a steering angle; and a central processing unit programmed to establish the braking command according to the physical parameter measured by the inertial unit and to transmit the established braking command to the braking device to apply to the castor a braking torque that varies according to the steering angle.
