A cute Arduino powered spherical quadruped robot has been created by Gregory Leveque, using an Arduino Nano, along with a 16-channel servo driver board.

Talkbot will cruise around until a bump sensor slams into an obstacle. One of his prerecorded messages will then play through the speaker while he backs up, turns, and tries to find a clearer path.

An Arduino-based robot for people who don’t know how to build robots "Sparki" ideal for teaching kids (or adults) how to program robots.
