Snailbot is one of my favorite pet projects. 🙂 The idea is to build a robot inspired from a biological creature, in this case, a snail. The first challenge was to design and wire-up the electronics so that they would fit inside the limited space of the snail shell. The electronics include an Arduino Nano microcontroller, a motor controller, two tiny gear motors with wheels, a lithium-polymer battery, an xbee radio for data transmission and remote control, an SD card and sound module, a tiny speaker for sound effects, and two ultrasonic sensors that will serve as Snailbot’s eyes.
Snailbot isn’t done yet, but I’ve made good progress.
