The present disclosure provides a robot and an adjustment method for a suspension system of a robot. The robot includes a robot body, a detection system, and a controller. The robot body includes a mobile chassis. The mobile chassis includes a suspension system. The detection system and the suspension system are electrically connected to the controller. The detection system is configured to detect operating information of the robot body. The controller is configured to control the suspension system to adjust a suspension hardness of the suspension system based on the operating information. The operating information includes at least one of ground information during operation of the robot body and pose information of the robot body.

A method for monitoring a vehicle, the vehicle comprising a control unit and an air suspension system, the air suspension system comprising pressure sensors configured to provide data representative of operating pressures of the air suspension system. To improve the monitoring of the vehicle, the method comprises determining a centre of mass of the vehicle by the control unit on the basis of data provided by the pressure sensors at least once during operation of the vehicle.

System and method for improving braking efficiency by increasing the magnitude of a frictional force between a tire of a vehicle wheel and a road surface. Braking efficiency may be improved by controlling the normal force applied on the wheel, with an active suspension actuator, based on the wheel's slip ratio.

Suspension systems for recreational vehicles are disclosed. The suspension systems may include at least one adjustable member coupling a sway bar to respective suspensions. The suspension systems may include a torque actuator associated with a sway bar.
