I remember watching this about 5 or 6 years ago.
It was a live action show with a few seasons, about this family with this inventor guy and his wife and son. He lived in a house that was very integrated with technology.
In his basement he had these three teenagers who were part robot and had powers, but they looked just like humans, and the story was about the three teenagers trying to fit in at the local high school with the inventor's kid helping them. I also remember there being something about bionics.
