Figure 4.3 is the schematic for the SumoBot robot’s IR object sensing. Build this circuit
on your SumoBot. Note that the 220 Ω resistors are already built into the SumoBot PCB;
just plug in the IR emitters and your SumoBot will be ready. When aligning the IR
emitter "headlights" it's a good idea to angle them slightly outward to give the SumoBot a
wider field of vision.
