Updated Components Diagram

This is still preliminary, but it's been updated to show more detail and some new decisions. Instead of the IMU package it looks like we're going to go for the raw components: one triple-axis accelerometer (the one used in Wiimotes actually) and three rate gyros. We'll have to write our own firmware to integrate the gyro rates and come up with actual position and orientation in conjunction with the GPS module. This came up after a discussion with our advisor Damian Toohey. It'll be more work and a bit riskier, but it's also probably more fun and we'll get a lot more from it. I also detailed how I plan on using multiple microcontrollers. This still needs to be proven out since there are concerns about communication speed involving both the multiplexers and controller to controller communication.
