Design Problem- In this assignment we were required to design, program and build a robot that is capable of following a black line that had white gaps along the way using a light sensor.
Solution- Throughout the whole day Team Lego has been trying out different ideas to see which, if any, works best. Our first thought was to simply time the robot to follow a black line for a certain amount of time and then a white line for a certain time period. We discovered that this was an insufficient strategy because when following the "white line" the robot got confused because the whole board was white. We then tried to use two different sensors and have them take turns controlling the motors so that when one sensor is on the white the other would be detecting the black thus moving the robot along the line. This strategy was too complicated for our limited programming capabilities so we are currently working on something different.
Experience- Today was yet again another stressful day because we had to try so many different ideas and none of them seemed to work the way we hoped. Nevertheless we have made progress by knowing what DOES NOT work, now we have a clearer idea of what to do. Also today we received our results for the last challenge, the line following, and as you can see we were ranked in 2 place, check it out!
