Robinson earned Virginia Prep LeaguePlayer of the Year honors after averaging 24 points, ten rebounds, three blocked shots and two assists per game for Christchurch School in 2013–14 en route to a runner-up finish in the VISAA Division II State Championship. He was recruited by Billy Donovan and chose the University of Florida over Connecticut, Indiana, Notre Dame and Oklahoma State. Despite being disappointed as Donovan left the Gators for the NBA prior to his sophomore year, Robinson stayed at Florida. "Devin runs like a deer and gets his jump shot off so quickly He’s a very talented guy. He can be a force at both ends of the floor", Florida head coachMichael White described his game in March 2017 according to richmondfreepress.com. Robinson averaged 11.1 points and 6.1 rebounds a game in the 2016–17 campaign and then decided to forgo his senior year to launch his professional career and enter the 2017 NBA draft.
Professional career
He went undrafted in the 2017 NBA draft, but joined the Washington Wizards for the 2017 NBA Summer League. Based on this performance, Robinson was signed to a two-way contract by the Wizards on July 14, 2017. He became the team's second two-way contract that year, meaning he also splits time between the Wizards and a G League that best suits Washington's area. On November 2, 2017, Robinson was assigned to the Delaware 87ers of the NBA G League, and later in the season, to the Westchester Knicks. Playing for the Wizards in the 2018 NBA Summer League, Robinson led the team in scoring with over 19 points per game. On April 13, 2019, Robinson was arrested and charged with disorderly affray for an altercation with Jalen Mills of the Philadelphia Eagles, outside a DC nightclub. Robinson was taken to the hospital with injuries. Later in the day the Wizards said that they would not be extending Robinson's contract. Robinson joined the Portland Trail Blazers for the 2019 Las Vegas Summer League. On July 23, 2019, the Toronto Raptors announced that they had signed Robinson. They released him on October 19, 2019. He was then added to the roster of their G League affiliate, Raptors 905. Robinson averaged 17.5 points, 7.3 rebounds, 1.9 assists, 1.1 steals, and 1 block per game, shooting 55% from the field.
