The Robonic Stooges was indeed on CBS; it was a segment of the live-action series "The Skatebirds" (1977). However, the Stooges was the most watched part of the show (airing twice each week), so in January of 1978, CBS gave them their own half hour, retitled "The Three Robonic Stooges," which would resurface on CBS two more times. It now airs as short features at the end of selected shows on the Boomerang channel.
The mindset is that because it's by Hanna-Barbera (animated at their Australian outlet), then by default it's a terrible show. For the sake of argument, I'll grant that it's not the best show, even by what's acceptable by Saturday morning standards. The atypical H-B animation, the half-baked situations, the dialogue, all the hallmarks to all that hold Hanna-Barbera as animation anathema. However, unlike other H-B shows at the time, "The Robonic Stooges" wasn't afraid to make references to its medium (the H-B studio appears in one episode) or even reference other comedy teams (the Marx Brothers in another).
We really didn't need another superhero cartoon in 1977; the cheese and camp of "Superfriends" was more than we needed or deserved. The Stooges could have very well been acceptable without the superhero take, but it was terrific in contrast to the other "Skatebirds" feature, the dreadful "Wonder Wheels."
