What kind of lights will be used in the maze?
20 watt halogen lights (the kind used for under cabinet lighting) Q: I am having trouble figuring out how to get the robot to judge distances. When it gets to an intersection, how does it determine which direction to turn? The robotics book says that it can only go to about 25 centimeters (about 10 inches). I have read the section on frequency sweeps, but I am not comprehending it (at least the part of reading longer distances). Any help that either of you can give me would be GREATLY appreciated. A: The main issue affecting the maximum IR distance sensing is the color of the reflecting surface (IR absorption). The second issue that affects distance is ambient light. The more light, the less distance. In our testing, we found that gloss white surfaces offered the best distance. We were able to achieve a maximum reliable distance of about 23 inches. we did quite a bit of frequency experimentation to get it there. We recommend that you reproduce the conditions of the contest (corridor wi
