Arduino Controlled Car

Here's how I created a self-guided car using Arduino and a sensor to steer clear of obstacles. Since the original outer casing didn't accommodate a battery, I built an extra one to hold a 9-volt battery. To ensure my 3D printer could handle the dimensions with precision, I added left and right sides. Initially, I planned for the rear wheel to be a gear-type design, but later changed it to an omni-directional wheel instead. Unfortunately, I've lost touch with the finished product - I can no longer find any pictures of it since it was given away to the school.
