Robot Jones (voiced by Bobby Block) is a robot who does whatever he can to fit in the human society, which can sometimes go awry. Whenever the day ends he adds to his memory called Data Log Entry something he learns through the experience. His brain is a giant light bulb. During the Pilot, season one, and pre production for subsequent episodes, Robot Jones (and several other robot characters) utilized speech synthesizers typed and edited by Greg Miller. There is debate whether Robot Jones's voice is from Macintalk Junior, Microsoft Agent Junior, or both. However, there is more than one vocal pattern, such as when he fainted in Sickness. During Season 2, Bobby Block was hired to dub all the episodes.
Dad Unit is Robot's father. When he says something, he often says it three times. He has one hand, wears a tie and in his focus on tasks he often gets into shenanigans such as smashing through walls. He is voiced by Macintalk Ralph.
Mom Unit (voiced by Grey DeLisle) is Robot's mother. She is pink in color and her hands look like the ends of a gas pump's hose which she uses for giving fuel to her fellow units. She seems to generally have a no-nonsense attitude.
Socks (voiced by Kyle Sullivan) is the best friend of Robot Jones. He is quite a fanatic to rock music. He has blond curly hair and wears a green jacket.
Cubey (voiced by Myles Jeffery) is the shorter friend with dark, straight hair, sunglasses with window blinds for lenses, and roller skates. He is a video game lover.
Mitch (voiced by Gary LeRoi Gray) is a lad often seen wearing headphones, a red sweater and sandals. His eyes are obscured by his long hair. In "Scantron Love", his last name was Davis.
Recurring[]
The Yogman Twins (voiced by Josh Peck and Austin Stout respectively) are the notorious young genius twins of the show. They wear red hats that resembles the 1980s band Devo's energy dome hats, yellow shirts, and black sneakers. Lenny is tall while Denny is short. They do whatever they can to take Robot's brain.
Shannon (voiced by Grey DeLisle) is a girl whom Robot loves because she has more mechanical attachments than any human he has ever seen, specifically a large orthodontic appliance and a prosthetic leg. She is unaware that Robot has a crush on her and typically finds him more of an annoyance than anything else. Shannon talks with a lisp.
Mr. McMcMc (voiced by Maurice LaMarchie in the pilot and Rip Taylor in the series) is Robot Jones's math teacher.
