A product of Pennsylvania State University, Brighton-born Robinson made his debut in September 2003 against Middlesbrough, in a League Cup Second Round tie at the Riverside Stadium, and became Brighton's youngest-ever scorer (aged 16) three weeks later in a cup match against Forest Green Rovers.
On 28 October 2006, Robinson scored his first hat-trick for Brighton in a League One game against Huddersfield Town, the first hat-trick by a Brighton player in nearly five years. He scored a second hat-trick in the FA Cup game against Northwich Victoria on 11 November 2006.
In June 2009, Robinson agreed to join League Two side Shrewsbury Town on a two-year contract. Robinson made an excellent start to the 2010–11 season, scoring the third hat-trick of his career as Shrewsbury beat Bradford City 3–1 on the opening day.
On 31 January 2011, Robinson joined Torquay for the remainder of the season in a deal that could potentially see gulls player Nicky Wroe moving in the opposite direction. He made his debut for the club the day later against Hereford United, scoring within the first 10 minutes of the match. On 2 February it was revealed, however, that the player had not been registered and thus ineligible to play.
Due to an oversight in the loan deal it was revealed that Robinson was eligible to play for Torquay against his parent club Shrewsbury. This proved costly as later on in the season Robinson scored twice for Torquay in their 5–0 drumming of Shrewsbury. Robinson then went on to play for Torquay in both legs of the League 2 Play-off semi-final, which by coincidence was against Shrewsbury Town. Once again Robinson proved to be a valuable asset to Torquay as they won the first leg 2–0 and drew the second leg 0–0, meaning Torquay were through and Shrewsbury were out.
In May 2015, Robinson was named the Fan's Player of the Year at Whitehawk after a run which saw him net 17 goals in the regular Conference South season. He left the club in 2016 to join Hemel Hempstead Town where he scored 25 league goals in his first season, before becoming Billercay Town's record signing in March 2017 when he joined the club for £24,000. In April 2018, Robinson wrote himself into the record books at Billericay by becoming their highest ever goalscorer in a season with 52 goals . Remarkably this feat was completed with league games still left to play.
