The WillDo Rotadrive has been designed with a view to simplicity in use, optimal manoeuvrability and a minimum amount of moving components. In order to accomplish this, we have selected a hydraulic drive. The assembly consists of four main components:

1. A hydraulic pump, connected to the diesel engine which is permenantly rotating, as long as the engine is running. The flow of the hydraulic pump is controlled by changing the number of revolutions of the engine.
2. The connection between the hydraulic pump and the Rotadrive is made by means of three flexible tubes of 25, 20 and 14 mm diameter, respectively.
3. The Rotadrive is equipped with an integrated tank or, if preferred without a tank. In that case the seperate hydraulic tank could be installed in any convenient place and position.
4. The Rotadrive is controlled with the help of a touchscreen on which a windrose is projected. By means of the throttle and the good old steering wheel all control directives are transmitted to the Rotadrive and the diesel engine.
