Robinson, who has bagged four goals in seven games for the Shots, put pen to paper on Monday and will now stay on the Rec until the end of the Play-Off campaign.
Brighton, however, do have a 24-hour call-back policy which takes Robinson away from the Rec whenever the Seagulls need him.
Boss Terry Brown said: "It's good news, although the call-back is a slight concern for us. I was kind of hoping Brighton would have more points in the bag."
Shotsweb however have stated that the deal has not yet been signed.
