An apparatus determines a road friction of a commercial vehicle. The commercial vehicle has a first axle and a second axle, a load distribution mechanism for changing a load on the first axle or on the second axle, and a slip sensor for determining a slip value for at least one wheel on the first axle or on the second axle. The apparatus includes an evaluation unit configured to control the load distribution mechanism to change the load of the first axle or on second axle, determine a change in the slip value in response to the change of the load, and evaluate the road friction based on the change in the slip value.

This invention discloses a slip sensor based on uneven charge at a contact interface, and a robot hand and foot. The sensor includes an electrode layer and a base layer, with the electrode layer disposed on the base layer. The electrode layer comprises four orthogonally symmetrically distributed electrodes: a front electrode, a rear electrode, a left electrode, and a right electrode. The electrode layer is used to contact the surface of a contact object. When relative sliding occurs with the surface of the contact object, each electrode generates a corresponding voltage signal. This invention can not only determine whether slippage has occurred, but also obtain specific information such as slippage distance, speed, and direction. It is manufactured using common manufacturing techniques while ensuring high slippage detection accuracy, enabling the robot to prevent slippage in a timely manner, or to make reasonable adjustments through output signals when slippage occurs.
