It is one-sided in the wording. As I have read it Robert provided the technology and agreed to act as a technical advisor. As long as he does (did) that he has not breached. That is even if he took over the development/engineering and then sat on it. The company could have gotten the development/engineering done other than via Robert; that is what they licensed, the rights to develop/market product based on the technology.
On the other side, Robert apparently can expect the company will make use of, make headway on exploiting the licensed technology, else the company would be in breach.
That is my read.
