We start with a tutorial in the next chapter that describes how to build a robot, TuteBot, that is able to wander around a room and avoid obstacles. This example robot, pictured in Figure 1.1, is im­ plemented without recourse to a microprocessor. TuteBot is merely an agglomeration of switches, relays, motors, and discrete electronic components, all of which can be assembled rather easily. You will be able to adjust TuteBot’s reflexes by tweaking two potentiometers.
