I've finally completed our electrical schematics for our 2012 MATE ROV bot. They were specially designed to be compact enough to fit inside a 3" pressure housing. This year I'm experimenting with all kinds of different technologies, such as surface mount devices and double layer PCBs. Electrically, this year's bot will be similar to last year's. We will have an "extended H-Bridge" (direction control bottomside and potentiation control topside) controlling our Z-Axis motor group, individual H-Bridges bottomside for both of the X axis motors (A new feature on this year's bot), as well as H-Bridge style control for the manipulator (which allows us to throttle speed to our heart's content). All in all, the control system for this year's project will allow us to achieve maximum controlablity and speed, while being the most compact control system Tachyon Robotics has ever created (albeit the third). We've also created room for 3 sensors and a pressure sensor, which gives us a lot of leeway to incorporate the special tools required to solve the tasks provided by MATE. All essential electrical work should be done in the next 2 weeks!
