appreciation to arduino and all of you great guys

see what i was able to create with arduino; 2018 INTELLIGENT ROBOT (AUTONOMOUS UNMANNED ROBOT) - YouTube

The kind words in your Title are appreciated.

However I think a Title that summarises your project would be more appropriate in this section of the Forum - it would help people to find it. Maybe "Arduino autonomous 4-wheel robot"

If you edit your Original Post you can change the Title.

PS ... a write-up that would enable other Forum users to make their own copies of your robot would be a great way to express your appreciation.
