Imahara was also a chief model maker with Industrial Light & Magic (ILM) on such movie projects as Galaxy Quest. In 2005, Imahara joined the cast of Mythbusters as a member of the Build Team, appearing in over 200 episodes of the series until his departure in 2014. In 2010, he designed the animatronic "robot skeleton" Geoff Peterson to serve as a sidekick on The Late Late Show with Craig Ferguson. He starred in the 2016 Netflix series White Rabbit Project alongside his MythBusters co-stars Kari Byron and Tory Belleci.
Imahara died on July 13, 2020, at the age of 49, after suffering a ruptured intracranial aneurysm.

## Early life

Imahara was born on October 23, 1970, to a Japanese-American family in Los Angeles, California. His Japanese name is Imahara Masaru (今原 真申). Imahara graduated from the University of Southern California (USC) with a Bachelor of Science degree in electrical engineering. For a time, he considered switching majors with the intention of becoming a screenwriter, but he decided to stay on the engineering track after assisting Tomlinson Holman, a professor at the USC School of Cinematic Arts.
Imahara was also a live-action role-playing gamer, as revealed on White Rabbit Project.

## Career
### Early work

After graduation, Imahara was hired as an engineer for Lucasfilm's THX division; he then moved to the company's visual effects division, Industrial Light & Magic (ILM), where he worked for nine years.

Artificial Intelligence, Star Wars: Episode II – Attack of the Clones, Terminator 3: Rise of the Machines, The Matrix Reloaded, The Matrix Revolutions, Van Helsing, and Star Wars: Episode III – Revenge of the Sith.
Imahara has been credited in many feature films as a model maker. In particular, he was credited for his work in updating the aging R2-D2 robots for the Star Wars prequel trilogy. As an official Artoo Technician, he made a cameo appearance in the mockumentary R2-D2: Beneath the Dome. He was also credited as chief model maker for Industrial Light & Magic on such projects as "Galaxy Quest" in 1999 wherein he designed custom circuit boards to provide the lighting effects on the NSEA-Protector space ship engine nacelles.

### MythBusters

Imahara joined MythBusters on the invitation of friend and occasional employer Jamie Hyneman and former ILM colleague Linda Wolkovitch, who was an associate producer of MythBusters. He joined as the third member of the Build Team alongside Kari Byron and Tory Belleci, replacing former MythBusters welder Scottie Chapman. His colleagues often jokingly refer to him as the "geek" of the Build Team. He often built robots that were needed for the show and specialized in operating computers and electronics for testing the myths. Imahara, along with Byron and Belleci, left the show after the 2014 season.

### White Rabbit Project

Imahara reunited with Byron and Belleci for the 2016 White Rabbit Project, a Netflix Original Series, in which the team investigated topics such as jailbreaks, superpower technology, heists, and bizarre World War II weapons, evaluated against a defined set of criteria and explored through experiments, builds, and tests. The complete first season of the series was released on Netflix on December 9, 2016. Despite receiving good reviews, the series was not renewed.

In addition to his role on MythBusters, he is known for his appearances on BattleBots, where he designed and competed with his robot Deadblow. By 2018, he was selected as one of the judges for the eighth season on BattleBots. He made a cameo appearance on Syfy's Eureka and the web series The Guild. Other works include designing the circuit that creates the rhythmic oscillation of the arms of the modern Energizer Bunny; leading Team ILM to victory in an appearance on Junkyard Mega-Wars; and authoring Kickin' Bot: An Illustrated Guide to Building Combat Robots (ISBN 0-7645-4113-7)
Imahara was a cast member and story writer for the short film Architects of Evil, created for the 2004 Industrial Light & Magic Backyard Film Contest. He was a mentor for the Richmond High robotics team Biomechs #841 for the FIRST Robotics Competition, lending his expert guidance on how to create the right robot for the right job. Imahara was profiled in the magazine IEEE Spectrum for an issue focusing on engineering dream jobs.
One of Imahara's independent projects, during early 2010, was constructing a robotic sidekick for Craig Ferguson, host of The Late Late Show. The robot, named Geoff Peterson, was unveiled on The Late Late Show's April 5, 2010, episode. It was controlled and voiced by comedian and voice actor Josh Robert Thompson.
In 2012, Imahara's likeness was used in the popular webcomic America Jr, in which he appeared as himself as a celebrity judge for a competition to select the country's Surgeon General.
In 2012, Imahara had a cameo role on the finale of Eureka, in the episode titled "Just Another Day", as a robotics scientist operating EMO.

On May 21, 2018, he was included as an author on the Disney Research paper "Stickman: Towards a Human Scale Acrobatic Robot", which explores the creation of "a simple two degree of freedom robot that uses a gravity-driven pendulum launch and produces a variety of somersaulting stunts". On June 29, 2018, Disney revealed that the Stickman prototype had evolved into an innovative, autonomous, self-correcting, acrobatic style of audio-animatronic figure, named Stuntronics, which will be utilized within Disney theme parks throughout the world.
In March 2020, while Imahara was working as a consultant for Disney Research and a mechanical designer at Spectral Moon, he built a fully animatronic model of Baby Yoda with the intention of touring children's hospitals with the lifelike robot to cheer up sick children. Imahara spent three months on the personal project doing the mechanical design, programming and 3D printing and completed it four months prior to his death.

## Personal life

Some of those props had been built by Imahara during the more than 200 episodes that he appeared in Mythbusters between 2005 and 2014.
Several months after his death, BattleBots co-founder Greg Munson announced on an episode of The Adam Savage Project podcast that it had renamed its "Best Design Award" to the "Grant Imahara Award for Best Design" as a tribute to Imahara.
In the Dungeons & Dragons web series Critical Role, Imahara is honored by Dungeon Master Matthew Mercer as a non-player character known as Imahara Joe. Imahara Joe is a tinkerer who helps the main characters build mechanical automaton motorbikes to achieve their goals. Mercer tweeted that Imahara was "one of the most lovely people I have ever known".
