Robinson was a young adult actor and stunt man and appeared in such films of the 1950s as Diary of a High School Bride and Beast from Haunted Cave.

He then appeared on another soap opera, The Bold and the Beautiful as Jack Hamilton, joining in the early 1990s and leaving after three years.

Robinson returned to General Hospital after a 16-year absence in 2002, only to see his character of Rick killed off in a controversial storyline that altered the back story.

The commercials aired on national television, and began with the quote, "I'm not a doctor, but I do play one on TV".

He was allowed to continue his role on General Hospital under a prison work-release provision.
