A little computer with a "brain the size of a planet" (to quote Douglas Adams, the author of Hitchhikers Guide to the Galaxy) is perfect to be the brain of your own robotic creation. In reality, the Raspberry Pi probably provides far more processing power than a little robot or rover would need; however, its small size, excellent connectivity, and fairly low-power requirements mean that it is ideally suited.
This chapter will focus on exploring the various ways in which we can combine motors or servos to produce robotic movement and use sensors to gather information and allow our creation to act upon it.
