This is my first robotics project. It has an OOPic controller, 2 hacked servos, A Sharp GP2D12 Infrareddetector and all are placed on a toy car. With this configuration it can avoid obstacles in front of it. I am going to get more sensors to make it roam around without bumping into anything. It just took a weekend to build. It costs around $90.00 for the controller, motors, sensor and the car.
