He created TINKER, an eight year old girl who's the grand-daughter of famous Silver Age Roboticist and Science Adventurer DOC TITAN. When her family vanished, Tinker was left in the care of her family compound, raised by an army of robots and her A.I. 'Mother', including TONKA, her best pal, playmate and bodyguard.
As a result, she can communicate with and control robots and electronic machinery.
Here she is accompanied by her robo-dog, Buttons... her flying 'helping hand', Yoyo... and Tonka.

And here's TONKA in his 'Rescue Suit'. He was originally designed to be able to perform rescue operations in natural disasters. It can turn into a blimp and a truck and a helicopter!
