Colin the Security Robot (solar arduino rover robot)

His name is Colin the Security Robot (per HHG2G). As of now he avoids obstacles with the help of a servo-mounted ping sonar sensor. The body was a H2 hummer (with treads for some reason?) rc car from stop and shop. He has a 9.6 volt rechargeable Nicad battery for power which will be solar charged. As you can see in the video the solar panels have not been installed yet. When encountering an obstacle directly ahead of it, Colin lifts up the car roof in surprise. This roof is where the panels will be mounted with some photoresistors for solar tracking.

more specifics: two full rotation servos drive the tracks. one standard parallax servo rotates the head. one rc servo from spektrum moves the roof. The spektrum servo seems to use more power than other brands and I had to power it separately using the original 4 AA battery compartment on the car. I plan on getting another parallax servo, or maybe futaba from sparkfun. hopefully this will eliminate the need for separate battery power and simplify the solar charging setup.

The board is mounted inside an altoids tin and protected by another tin with a duct tape hinge for easy access.

The ping module is set in a mini breadboard and protected by a carved up deodorant stick cap covered in duct tape.

All questions and suggestions are welcome!

sorry i don't have a tutorial for this one.

Great job! Did you program the sweeping motion that the IR sensor makes or is that something it naturally does?

I programmed the sweeping motion. It just goes 90, 180, 0, 180 degrees. That creates a repeating pattern!

how to make?
