Formica Expansion Board Complete

It's been a while since I've written about this project. This is because the deadline is rapidly approaching and there is still a considerable amount to do. First, here is the final thing:

The main problem we are experiencing is trying to get pictures out of the chip quick enough. At the moment we can only manage 4.6fps which is quite poor. Despite increasing the speed of the SPI link, the chip itself is holding us up the process. In returns 'invalid data' if you read it any faster than we are doing so at present.

The second problem we're having is a mechanical one. With the rather large eyes at the front, most of the robot's weight is *not* over the rear wheels, so we loose traction and consequently directional and speed control is proving tricky.

The final presentation is on Thursday and the demonstration some time next week. Busy days.
