Lab 5: Light Following

Attach:ScottBrait.jpg Δ

Introduction

My objective of lab 5 was to program the Create to search for a light source, and home in on it. Once it reached the light, I then wanted it to stop driving. The code was written so the robot could quickly and effectively find the light, regardless of any obstacles that were in its way (i.e. - chairs, desks, people, etc.).

Lessons Learned

- The values of the photocell sensors are dependent on their placement on the Create, how they are presented (in a straw, with colored tape, etc.) and the height of the light source (if it is level with the robot, or up higher than the sensors can detect). Unfortunately, I didn't realize this until I had already worked on this lab for hours upon hours, while removing and reattaching the sensors each time. Doing so made the lab extremely difficult for me due to the fact that I was getting back different values each time I sat down to work on my code.
- The photocell sensors should be calibrated or their values should be adjusted based on the ratio of the different readings. I used two in my experiment, and they did not detect the same numbers, which also made the entire lab a more difficult and tedious process.
