Electronics and radio-control specialist Grant Imahara is a former animatronics engineer and model maker for George Lucas's company Industrial Light and Magic (ILM). While he was there he worked on movies including The Lost World: Jurassic Park, Star Wars: Episode 1 - The Phantom Menace, Terminator 3: Rise of the Machines, AI: Artificial Intelligence and The Matrix Reloaded.

In addition to operating R2-D2 (he was one of only a handful of official operators), Grant has another claim to fame. He developed a custom electronics circuit that kept the Energizer Bunny's arms and ears moving at a constant rate. In fact, he's responsible for all the electronics installation and radio programming on the current generation of bunnies, even serving as the bunny's driver and crew supervisor on numerous commercials.

Although he has a degree in electrical engineering from the University of Southern California, Grant picked up many of his mechanical skills from the machinists at the ILM model shop, many of whom have been there since 1986's Howard the Duck. He's also the author of the book Kickin' Bot: An Illustrated Guide to Building Combat Robots. His own machine, Deadblow, is a BattleBots champion that continues to strike terror into the hearts of fellow competitors.
