For many years, robots and other advanced electronic wonders could only be seen on the television, movies, or in university or military labs. In recent years, however, the availability of new and inexpensive hardware and also free and open source software, has provided the opportunity for almost anyone with a little technical knowledge and imagination to build these technical wonders. The first wave of projects were fueled by Arduino, an inexpensive and simple-to-program microcontroller. The next wave was carried further by the introduction of the Raspberry Pi, an even more capable processor powered by the Linux operating system.

Now there is an even less expensive, powerful microprocessor: the Raspberry Pi Zero. This little processor packs a processor powerful enough to run Linux into a small and even less expensive package. This capability, coupled with some additional power, inexpensive hardware, and free open source software provides a platform for projects that range from simple wheeled robots to advanced flying machines.
