Well i have started working on next years scienc project and I'm still trying to figure out if i want to use a GPS and just move to waypoints or to get sonar and go fully autonomous. I also am not secure in my controller, either stamp or a laptop.

wow this is a cool site. another thing i built was a little walking robot that used a basic stamp board and 2 servos. it was really hard to make but it worked and searched for light usung a 2 photo electric cells. i uploaded a pic of the care bot( the last prototype of the science project)
