The Distance Sensor, shown in Figure 8-1, measures the distance to an object in front of it. It can, for example, tell a robot that it may be about to run into something. Alternatively, it can trigger some action when an object gets close. This chapter will describe how to work with these distance sensing functions, first with a new type of tape measure. Then the chapter project will build a cannon that scans an area to monitor for a target to shoot at.
