Ok, here is the scoop; it is the control box and transmitter for a radio control system custom built by John Barnes, a frequent poster on lugnet.robotics, which he sent to me just after Christmas. It really makes a big difference to models for sure - no more umbilicals! Here are some specs; I am not entirely familiar with the inner workings, but am sure John would be happy to help here: - Radio control (not infra red) - appears to have a large range, does not need line of sight like IR so can go through walls etc. - 8 channels, so up to 8 motors or other 9V devices can be controlled independently. Two of the channels are "heavy duty" ones which can drive multiple motors simultaneously. - The receiver has dimensions of 8x4x2.66, very similar to the small black 9V battery box. Eight standard 2x2 lego connectors fit directly on the top of the box. In the truck model this receiver is "disguised" as a diesel tank. - Powered by an external battery source to allow the user best choice of battery box for the application, as well as allowing non remote controlled devices such as compressors to be powered from the same battery source. - Control box has 8 sets of buttons, one for each channel. Four sets have two and are instantaneous, so the motors will move only when the button is pressed and held down. The other four have three buttons, one for forward, one for back and the other for stop, so continuous motion without holding down a button is doable. I believe that John is planning to build more of those for sale, so if you would like one you know where to go. Any comments John? Jennifer Clark
