Robinson, who has not started a game for the Seagulls this season, spent a month on loan with the Shots in 2005 and is hoping to recapture the form he showed in his last spell with the club, when he bagged four goals in eight appearances.
He told the Aldershot News and Mail: "Obviously, I may well be looking for a new permanent club come the summer, so I really hope I can do well at Aldershot.
"Things had gone a little stale at Brighton and this is the move I needed.
"I'm delighted to be back and to be given the chance to play competitive football again. I had such a good time when I was at Aldershot last time and that was definitely a factor in coming back here on loan."
