After a thorough analysis we have decided on short notice that the radio control will be redesigned. As all parts are ultra compact, we have put a crosslever and various buttons in a singlehand unit. As we know from former projects it is quite awkward to use a radio control built into a medieum sized watertight case and drive the crawler by means of to separate levers. Now we are able to address all functions via a light unit, that is held in one hand.
Even with the compact dimensions there is display built in. The most important information is the inclination of the crawler lengthwise and crosswise. You can capture that very easily in a circular symbol. Naturally all other info, such as pressure, etc. can be retrieved as well.
