It will be the second time Robinson has spent time on loan with the Shots. He became a fans' favourite during a month-long stay in 2005 when he scored four goals in 10 matches.
Robinson has been at Brighton since he was a trainee and is Albion's youngest-ever goalscorer at 16 years and 355 days.
However, his chances have been limited this season. He has made just eight substitute appearances in all competitions, scoring once.
