I know this is a bit of a silly thing to ask for, but as i just need about 20$ till i can order all the stuff i need to build my robotic arm i was just wondering if someone could give me an idea of what to make with a two wheeled robot with an ir sensor. Sadly thats all i have at the moment. I use a bx-24 chip and a RAMB II motherboard. Iv built many different things like object avoiding, tabletop etc robots. So has anyone got any ideas as to a concept that would push the capabilities of my current set up?
