Abstract

General Idea:

Make a robot which can find a goal in a non-cycled maze (only with blind tracks) of black lines by going left on every intersection.

---

Thoughts:

At first we tried robot only with two sensors and he did quite well. But finally we had to rewrite a source code for three sensors robot in a very short time because of troubles with implementation of two sensors ancestor. And that was the whole problem.

---

Results:

Our robot can follow the black line, it can recognize blind tracks and turn himself back to line. The only problem is with marking the intersections. Because robot hasn´t a ideal movement, there are still some inaccuracies. Theoreticaly we have some thoughts how to clean up, but we didn´t have enough of time to implement it right (viz. source code).
