Tips and Tricks with the Light Sensor

Yesterday, Amy, Emily and I worked for a few hours to de-bug the Smell (Pizza Molecule) mission.  We were experiencing turning problems at the competition, which was rather strange because our robot had performed perfectly at our practice table.  

When my sisters and I tried it on the table five out of five times it didn't work.  Our mom had given the rest of the day to work on robotics and we knew we had some time to experiment.  The three of us decided to test our old theory of following the line to the pizza molecules.  



As the four of us had gone through the tutorials for the NXT, we had a lot of success with the light sensor.  The team was able to get the robot to follow the line, but it keep sensing the colored molecules as black.  This started a series of test to find the right programming number so that our robot would only sense the black line as "dark" and everything else as "light".

I know this is a little late in the year, but for any team who has experienced the same difficulties, the number is 35.

As it turned out, we decided not to follow the line because of the time limit.  Instead, we used the light sensor to stop at various lines and preform certain actions.  Even though we weren't able to use the light sensor as much as we needed to, it was a great learning experience and I believe all of us gained a lot.
