My new hobby is robotics. I'm just starting out, and am currently programming for and building on the robot. This is what he looks like now (31-08-2011):

Modifications to the truck
Since the old electronics are of no use, I need something else to control the engine. This is what I'll use for now. The BEC is reportedly capable of supplying 3 A @ 5.5V. The connector for the battery is of the 'Tamiya' type, the connector for the receiver is of the 'JR' type.
This will be the eye of my robot. I bought it because it's standards compliant, and thus works (very well!) with the video for linux drivers. Out of the box (not bad for a Microsoft product is it?). Good image quality too. It's connected through USB.
The clip can be removed quite easily, however, the camera would still be able to rotate around the rest of the foot. I have not dared to open the camera any further to get rid of the foot. However, there's someone else who already hacked one (useful information about opening the casing) http://ghonis2.ho8.com/lifecam/lifecam1.html . I'll try that soon.
I'm not quite sure about the range sensors yet. For now, I have 2 IR range sensors GP2Y0A02YK, with a range of 20-150 cm. Apparently, these have a narrow beam. I have yet to test them.

I got me a parallax ping))), but have yet to test it.
This will move the camera and other sensors around, allowing the robot to analyze the surroundings without moving the robot itself.

The mini-PCI slot is quite vulnerable! I managed to wreck one of the 'fingers' that keeps the card in place, when removing the video card the first time I used it.
- know up from down (gravity).
- detect crashes.
- detect speeding up and slowing down.
- detect corners.
