Even in a world populated entirely by mechanical beings, Rodney Copperbottom is considered a genius inventor. Rodney dreams of two things: making the world a better place and meeting his idol, the master inventor Bigweld. On his journey he encounters Cappy, a beautiful executive 'bot with whom Rodney is instantly smitten, the nefarious corporate tyrant Ratchet who locks horns with Rodney, and a group of misfit 'bots known as the Rusties, led by Fender and Piper Pinwheeler.

Beyond the scope, freshness and vibrancy of an incredible world populated solely by mechanical beings, Wedge and his team are creating memorable robots, each with "his"/"her" own distinct personality. The result is a timeless tale that pushes the boundaries of animation, while introducing characters rich with whimsy, heart and soul.

"We took the script around to Robin, and he clamped onto the part of Fender," says Wedge, who allowed Robin lots of room for verbal doodling. "You just put the script in front of him, close the door and hope."

Robin says Fender, a walking junkyard of found objects, is "a self-made man - made from others. He is trying to hold it together, literally."

Fender is a robot whose head, arms and legs fall off at the most inopportune moments.
