How to get your Pi to go
There are hundreds if not thousands of things you can do with a Raspberry Pi and that's half of the attraction of everyone's favorite credit card-sized PC. One of the most popular projects, though, and one that has hundreds of its own dedicated add-on boards and associated components is robot building.
It's rarely easy to get started. You need the right motors for the chassis, the correct voltage for the sensors, and a way to power everything for more than 30 minutes without waiting another three hours for the batteries to recharge.
4tronix [1] think they have the answer with Pi2Go-Lite [2] (Figure 1). Like many other solutions, it offers a complete "one stop shop" kit, and all you need to do is add a Raspberry Pi and some AA batteries. It's cheap too, starting at UK£ 30, making it barely more expensive than the Raspberry Pi itself. At that price, of course, you need to assemble everything yourself and it does – even by the maker's own admission – involve quite a lot of soldering. According to 4tronix's build instructions [3], it will take about 90 minutes to put together from scratch.
