This prototype from the University of Bath is designed to develop and test the hydraulic rolling system and the electronic controller. The basic function has already been verified. The two videos show the first few metres of the test on the University of Bath site.

At the current time a range of software versions for the electronic controller for the hydraulic rolling system are undergoing tests. An extensive programme of tests will be used to improve the whole system, consisting of the hydraulics and actuators, steering, suspension and damper system as well as the electronics, consisting of the sensors, signal processing units and control equipment.
