At Robocup Iran Open 2007, I met these young scientists (age 16 to 20 years old) who managed to invent a mini-robot which could work based on the scents/smell of products.
It was an amazing mini-robot.
Apparently one of them, (the young scientist on the far left) did not accept the offer of MIT University.
He explained to me that he would prefer to stay in Iran rather than 'others' use his talent for themselves.
He was a patriotic young Iranian scientist.
I wish the best sucess for their future work.
