In the original competition, though not experienced by anyone on the project, the rover was said to have been unable to navigate to the beacon successful. However, the rover was able to navigate through obstacles relatively easily. Due to the detachment of the infrared sensors, version A of the code was not tested on the rover another time.
Due to the separate groups in this project, the hardware and wiring was not complete when version B of the code was completed. Upon finishing this code, the plan was to wait until it could be tested, but the idea for the triangulation caused the code to be edited so that the beacon tracking would be faster and more accurate. Thus, version B was abandoned to work on the new idea and never thoroughly tested.
Version C was never tested for several reasons. Firstly, like with version B, the rover was not completely assembled and thus testing was not possible. In addition, no equation was formulated to convert RSSI into distance. In the test measurements, the average RSSI at 152 centimeter was 226, but at 304 centimeters or twice the distance, the average RSSI was 20 greater or 246. In addition, if the beacon was rotated the RSSI would change drastically. On July 14th the average RSSI at 152 centimeters was 226. However, on the July 15th at the same distance the average RSSI was 241. Thus, version C of the code was discarded due to the discrepancy.
