Thank you for the reply! The robot must cover an about 10x10 mt area for a complete path of about 80 mt. outdoor. The car is a sort of lown mower 1,5 mt large and 0,8 mt long. It must cover 80 mt in 2 or 3 minutes. I'm an absolute beginner and I'm only trying to have some idea to find if my project is achievable.
Thank you again.
