| - | Additionally, depending on the length of track 1 used in the arming sequence, we will choose a number of times the respective if{} statement will be repeated. In this case it, is repeated 12 times. | + | If the distance is less than the defined distance to avoid obstacle means there is some obstacle ahead. So in this situation robot will stop for a while and movebackwards after that again stop for a while and then take turn to another direction. |

| + | After finishing the project, I learned that:\\ | ||
| + | *While the code is simple, the hardest part was the making of the chasis. | ||
| + | |||
| + | *Some parts have very tough bolts to unscrew which led to a lot of wasted time | ||
| + | |||
| + | *It was fun to see it work after all the effort put in it | ||

| - | O arhivă (sau mai multe dacă este cazul) cu fişierele obţinute în urma realizării proiectului: surse, scheme, etc. Un fişier README, un ChangeLog, un script de compilare şi copiere automată pe uC crează întotdeauna o impresie bună ;-). | + | |
| - | Fişierele se încarcă pe wiki folosind facilitatea **Add Images or other files**. Namespace-ul în care se încarcă fişierele este de tipul **:pm:prj20??:c?** sau **:pm:prj20??:c?:nume_student** (dacă este cazul). **Exemplu:** Dumitru Alin, 331CC -> **:pm:prj2009:cc:dumitru_alin**. | + | {{:pm:prj2022:robert:rob.png?linkonly|Electric Diagram}} |
