I'm about to start my first robot project so i thought i would document my progress, I don't imagine anyone else will be interested so i'm mainly doing this so i have a record.
For a project at Uni I have made a Wireless controller and a motor driver PCBs. They both include a built in arduino and communicate via XBees. I get to keep the PCBs from the project and have bought the ATmega328 chips, XBees and a chassis as these are the parts we had to return.
I plan to use this as a base for my robot and add more features as and when i can.
