Summary
In this chapter, you've been able to see a number of the different component parts that go into a robot, and through a block diagram as a plan, start to visualize how you'd combine those blocks to make a whole robot. You've seen how you can quickly sketch your robot ideas on an envelope, and that drawing tools on a computer can be used for a neater version of the same diagram. You've had a quick tour of motors, sensors, and controllers, along with a few ways, including analog, digital, PWM, and data buses, for controllers to communicate with the other devices connected to them. Following on from this, you've seen a plan of the robot we will build in this book.
In the next chapter, we will look at Raspbian, the operating system used on the Raspberry Pi in our robot, and start configuring it.
