my prototype vehicle

Last year, we were having a holiday in Brisbane, believe it or not. Anyway Mum and Dad gave Catherine and me over a hundred dollars (it was after the court case and was a special celebration). The first day we got there I went shopping. I saw this robot-making kit that you can programme from your computer. I bought it the next day.
Yesterday, I started working on my own robot design. I had already made 4 machines using the instructions from the book, but this one is the first one I have designed myself.
I called it Mark 1. It is a 4 wheel drive vehicle about 30cm long. The first thing it did was drive up my water bottle. I plan to modify it and put sound sensors and touch sensors on it so when it crashes into a wall, it will back up using the touch sensor. When I make a sound, it will stop or go.
This picture is the model with no sensors. The box on top is a computer, but I think it looks like a gun turret. More pictures when it is finished...
