Omar's Maze-Navigating Robot -- George School, 2007

My student Omar Mustardo has programmed his Mouse robot to navigate a simple maze. His robot is not autonomous (yet), but uses "dead reckoning" to navigate the course. (That is, the robot is not capable of making its own intelligent decisions.)

The key to Omar's robot's precise motion is the fact that he programmed it to turn super slowly using pulse width modulation (PWM). Note this is also a good demonstration of error propagation: a lot of very small error add up to an overall large error.

Omar's next step will be to program his robot to navigate the maze autonomously!

Robodyssey Systems manufactures the Mouse robot and RAMB II motherboard you see here. The robot's brain is NetMedia's BX-24 microcontroller, which is programmed using the BasicX language. I am the author of the world's only BasicX textbook; if you are interested in learning how to program your own robot, see my website at www.basicxandrobotics.com.

Is The Mouse robot a kit? I'm just getting into robotics and I have yet to build one, I am wondering what I should start off doing. Oh and by the way, what kind of sensor detects the walls?

Message me if you don't mind
