Maddy Bot remote control or auto avoid robot vehicle
Originally I built another robot vehicle using motors from a clock that spins around madly, a mobile phone holder an Arduino and motorshield with Bluetooth. Which could be remote controlled via a number pad using a Nano also with Bluetooth. Then I picked up this 80's BigTrack toy from a boot sale for a pound(£1), with visions on uses for it in projects that I've made or experimented with. So it's big, plenty of space to add extra stuff to!
