Imahara was also active in the robot combat community, regularly appearing on BattleBots during the early 2000s with his robot Deadblow and later returning as a judge. In 2018, Imahara hosted Home of the Future, a web series co-produced by The Verge and Curbed.

I’ve retired from robot combat. My first fighting robot Deadblow was almost 20 years ago in 1999. They made it into a toy and I wrote a book on the subject. #BattleBots pic.twitter.com/4LbxlKlI0v
