Today, Robert and I installed the line follower mechanism on our Boe-Bot. We also programmed and tested the line follower as seen in Figure 1; we are still in the process of troubleshooting it. The line follower mechanism allows the Boe-Bot to distinguish between light and dark areas. This quality is perfect for an obstacle course because we can lay down black electrical tape on a white background and program the Boe-Bot to "follow" the black electrical tape lines.

Robert and I also discussed the required objectives our Boe-Bot will perform to match those of the North Carolina road test that teenagers complete in order to receive a state driver's license. Below, Figure 2 explains our list of objectives in order from start to finish. These objectives were researched online and recalled from personal experience taking the road test.

The last thing we did during class was plan out the obstacle course for the road test. The obstacle course is based on the actual route used for the NC road test. Figure 3 is the rough sketch we will use to create the obstacle course for the Boe-Bot to navigate. We've decided to use foam board as the foundation for the obstacle course and electrical tape as the lines for the Boe-Bot to follow. The obstacle course will be explained in detail next week when we start to construct it.
