+===== Concluzii =====
+Building a robot is not easy and you need to pay a lot of attention to details,to do your research properly and have patience because it doesn't work perfectly from the beggining.I wanted to create something useful,something that I would enjoy using at home and something that would make me proud.I think it is complicated when you are starting but after a while,all that hard work pays off.
