I recently started a new robotics project: HummBot
In this project I will transform a hummer RC car into a robot car that finds its own way through a track.
The Arduino will control the HummBot. I will start simple with some IR sensors and a motor controller, but over time I plan to make HummBot more sophisticated by adding more sensors and maybe even a camera.

I'm looking forward to join this forum and learn my way through the world of Arduino!
