So ive just begun a project in tangent with our schools Underwater Robotics Team. My goal is to use the Raspberry Pi in order to replace the current control system, which consists of Three Lego NXTs and 6 Bread boards. As it is this project has only just begun, and we have until about December to get the whole thing working. my main goals are basic motor control, and camera usage. I was thinking that we could two Pi's together (one on board, one above ground) but i'm not entirely familiar with this area. I will try to keep this updated with our progress, but in the mean time, any suggestions, or ideas. the biggest problem we've run into so far is waterproofing the Pi up to at least 100 feet and still keeping it accessible.
