Why does the echo bully the weak?
01 echo effect
I. Introduction
Yesterday, I received a message from a classmate on the background of the official account. It reflects that the environment of the beacon group in their competition area is not satisfactory. He believes that sound beacons will be affected by positioning indoors due to the echo of the surrounding walls. But in the live competition, many indoor teams have achieved results. In the end, he decided that Echoes would only affect the average participating team. Great schools don't matter. He also suggested whether the preliminaries can be held outdoors, hoping that the smart car competition should be able to accommodate some average-level teams.
2. Sound beacon
Early sonic beacon competitions were played indoors. The reason why this year began to define outdoors is actually to hope that some competition groups can use GPS to complete positioning. However, due to the drift of GPS, there is no team that really uses GPS to complete beacons for assisted positioning. Therefore, now I suspect that the echo of the indoor competition caused my car model to fail to complete the preliminaries task, and it may be the wrong direction.
Here is an example, that is, in the complete model group in the North China Division, there are two competition venues on site, namely A and B competition venues. After the preliminaries, it was found that about 80% of the teams in field A completed the game, and 20% of the teams in field B finished. As a result, almost all teams that failed on venue B believed that it was the light on venue B that affected the performance of the game. Therefore, the organizer can only allow the teams that have not completed the game in the two venues to switch venues and re-match. The results of the competition showed that there were no teams that failed to score on venue B, and only one team completed the competition on venue A. Therefore, in order to find out the reason for not finishing the race without your own car model, you may still need to start from your own problems. Only in this way can we find the reason for the failure from this small failure. Only in this way can we accumulate more engineering experience and make greater progress.
※ Summary ※
This article analyzes the doubts of the students participating in the sound beacon group competition about the impact of echoes. In the same environment, others can complete the race, but your car model has problems. It is recommended to explore the possible bugs in the software and hardware inside the car model instead of simply blaming the echo.
