I took the BugBrain kit and put it together as a way to connect my kids' interest in the NASA Mars Rover mission to real world robotics. They are 3 and 5 years old and helped me put it together. Then I attended the Atlanta Hobby Robotics Club (AHRC) meeting and one of the members made a presentation of an IR object detection circuit. I enhanced the kit with this circuit and now BugBrain can see!

The web page has some diagrams and photos and downloadable BasicX source code. The BasicX is a pretty capable package. I used mutliple tasks to control the robot. My only gripe is that determining the 'stack size' is really tough. With only 400 bytes of total RAM, and each task taking a minimum of 32 bytes there isn't much wiggle room. My advice to someone trying to use multiple tasks is not to use BasicX strings at all - this includes the extremly useful 'Debug.print' function.

I'm pretty much "Done" with BugBrain now. It was a good kit to start with, but since I'm not a Windows person and am handy with 'C', I am going on to PIC chips for now (free samples!) and maybe will work with Atmel processors since the Linux support for development on those chips seems tto be so good.
