He died in a hospital in West Virginia, where he had been for over a month. He would reprise his role as Tommy this year for the YouTube TV series adaptation Cobra Kai. “I’m heartened to know how much Rob enjoyed and cherished his time working on Cobra Kai. We were looking forward to seeing his smiling face again this season, as we had plans for Tommy to ride again. But he’ll remain in our thoughts every day as we strive to make him proud. #RIP,” Cobra Kai writer-producer Jon Hurwitz said via Twitter.
Robert’s acting career began back in the 1970’s, with appearances in Starship Invasions, and Search and Destroy. His notable role was playing Tommy in The Karate Kid, back in 1984. The movie helped popularize karate and the martial arts in general in the US, and it earned star Pat Morita an Oscar nomination for Best Supporting Actor. He starred alongside Ralph Macchio and Pat Morita in the classic film, and was one of the members of the Cobra Kai dojo. Robert was also known for a variety of TV appearances. He is survived by his brother Patrick and his sister–in–law Linda.
