At 6-2, 200 pounds, Robinson brings the ability to play a variety of positions thanks to his strength and 4.5 time in the forty yard dash.
He is expected to challenge for time in the defensive secondary and is expected to be able to add an additional 20 pounds to his frame.
Former Riverview standout and current Duke assistant Jon Haskins was instrumental in recruiting the 6-foot-2, 190-pound Robinson, who could play a variety of positions.
Robinson spent most of last season at linebacker, but also played in the offensive backfield.
He was nominated for the Herald-Tribune's Sarasota Player of the Week award five times.
"(Robinson) comes from a good family and has a good work ethic," said Riverview head coach John Sprague. "He's such a good kid that (Duke) couldn't turn him down."
