// if the sensor sees gray (line edge) if ( reading < high && reading > low ) { TextOut(5,LCD_LINE3,"GRAY "); // the turtle goes straight OnRevSync(LEGS,100,0); } // if the sensor sees black (line) if ( reading <= low ) { TextOut(5,LCD_LINE3,"BLACK"); Float(LEGS); // the turtle turns left OnRev(R_LEGS,100); } // display the actual sensor reading TextOut(0,LCD_LINE2,"Reading: "); NumOut(50,LCD_LINE2,reading); Wait(100); } } At the beginning of the program, the main task calls the Tracking_init() function. This function is used to ask the user to set the two thresholds high and low, explained before (see Figure 6-5a). The TOLERANCE value (set to 3), added to the low threshold and subtracted from the high threshold, is used to narrow the range of values seen as gray, to compensate for the flickering measurements of the sensor. For example, if during the initial setup, the sensor reading stored for the black color is 35, the algorithm will classify as black every reading less than 38 (35+3). Assuming you stored a reading of 51 for the white color, the algorithm will classify as white every reading greater than 48 (51-3). So, the TOLERANCE value represents the tolerance used when discerning sensor readings (a tautology!). Once you press the orange button, the Tracking_init() function returns, and the line-following algorithm starts. The algorithm works as explained earlier, running forever inside the while(true) loop.

It s time to give your pet the spark of life! You ll see how to model an autonomous behavior for the turtle, to make it resemble a real one. Read the following description while looking at Figure 6-6, where you can see a comprehensive diagram of the turtle s behavior.

Figure 6-6. The diagram of the FSM implemented to simulate the turtle s behavior. The named boxes describe the moods, and the arrows represent state transitions caused by events. When the program starts, the turtle is in QUIET mood, and stands still in place. After a while, if you don t come close to its eyes, or if you don t scare it with loud noises, it could become bored or hungry. In BORED mood, the turtle decides to have a nap: it retracts its head and snores loudly. It wakes up on its own after a while, returning to QUIET, but could also be awakened suddenly by a loud noise, leading to a SCARED mood. Imagine how nervous you d be, awakened suddenly by a giant alarm clock! After a few naps, the boredom is so oppressive that it gets HUNGRY: it turns around, bites (fictional) grass, chews, and gulps. After quickly digesting, it burps unceremoniously. As said before, there are two ways to scare the turtle: coming too close to its head, and producing a loud noise. These two disrespectful actions cause the turtle to get SCARED to retract its head inside the shell and shiver with fright. If you continue to scare it, it will get ANNOYED and try to escape. Unfortunately, its laziness will soon get the better of it, and the turtle will slow down and stop after a few steps.
