  12. Photoelectric sensor

  13. How to detect We use photoelectric sensor module to accomplish our detection job. This is what it looks like on the controller.

  14. At first, we will set a trigger value on the robot. If the sensor acquisition value is higher than the trigger value, robot determines the value as true signal. Otherwise, does as false signal.

  15. Simulation I downloaded a software named Plasied2 to simulate the movement of tracing robot on black line. I assumed some parameters on car and tracks to complete my simulation.

  16. This curve directly displays the quality of algorithm.

  20. HOW TO CONTROL A ROBOT WITH NXT

  21. choose NXT1 as a host, Select :search: in the Bluetooth menu. We need select the channel number 1 to communicate with the other NXT. At this time ,enter into the Connection menu, we can see that the NXT2 occupies the no.1 channel in display NXT1 and NXT1 occupies the channel that is zero. In this way, the connections will be built between two NXT. It can be controlled by programs.

  22. The ConnetionsBetween Motor And Sentor • NXT controller include 3 output ports ,4 input ports and a USB port. • Port A: Expand function Port B: connect the motor left. Port: connect the motor right. • We choose the port 3 because it connects with photoelectric sensor.
