The S3 robot can detect the light after it reflects off an obstacle and bounces STEP 2: Put the power switch in the ON position. You will hear a song and back to its infrared detector eye. STEP 2: The S3 robot will drive around the room, turning to avoid objects. all 3 LEDs will light up. The LEDs will be green in a bright room (and yellow STEP 1: Press the reset button 2 times. in a dim room). STEP 1: Press the reset button 3 times. STEP 2: The S3 will play a short song, then drive around the room seeking the brightest light within its view. STEP 2: Place an object on the floor in front of the S3 robot. If the S3 sees the object on its right, the right LED turns on, and the speaker plays a tone. If no object is detected on the right side, the right LED turns red. Similarly, if the S3 sees an object on its left, the left green LED turns on and the speaker plays a different tone. If no object is detected on the left side, the left LED turns red. The S3s rear tail wheel is a stall sensor. If it get stalled on an object it STEP 3: Cover a light sensor with your cannot see, it will back up, turn, and try driving forward again. finger.

Other demos will use the indicator LEDs in a different way. EXTRA: If the S3 can see the object with both sensors it will play both tones and both green LEDs will turn on. The S3 can see light objects better than very dark objects, because dark objects do not EXTRA: You can cover the sensors with your fingers then press reflect much infrared light. and release the reset button to choose Demo modes.

If the S3 loses the line on a tight corner, it will turn back and forth to look for it again. EXTRA: The S3 robot must be resting on the paper to see the line. EXTRA: The S3 does best following black lines about 3/4 inch (2 NOTE: Just like handwriting, each S3 drawing will be recognizable cm) wide, on a white background. Line following works best when but unique every time you run a program. Variations occur as the track is placed on a hard, level surface. Carpet, tile, or other battery charge changes, motors warm up, and wheel joints relax uneven surfaces may not work well. A dark surface may show with use over time. through thin paper and make the line harder for the S3 to see.
