The Petoi Bittle is a bot that lets you achieve those dreams, and not only is it easy enough for young teenagers to get up and running, but it also has enough room to grow that engineers can tinker with it for years.

The base of this 'bot is a custom Arduino board, which coordinates all four legs and the head. The frame assembles like a puzzle, but it's only once the assembly is complete that the fun really begins. You can make it perform some basic moves by using an app that you download onto your phone or another device, and the dog won't be too old before you want to teach it some new tricks.
