I remember a show from when I was a kid in the 70's, it was a serial set on an island where the heroes, two men and one women, had crashed landed I think. There was an evil mastermind on the island who was trying to catch them (he had his minions pursuing them) and it also featured a Robby the Robot type of robot. It was pretty much sci-fi based. It may have been MYSTERIOUS or MYSTERY ISLAND but I can find a listing for it anywhere online. Some help would be appreciated, its been racking my brain for months!
