An image from the video that made the Maryland Batman famous. Youtube/Associated Press A Maryland man who was known for visiting sick children while dressed up as Batman died on Sunday night after his custom-made vehicle broke down on the highway, The Washington Post reports.

Lenny Robinson had been visiting children in hospitals since 2001, but he became famous after a video of his being pulled over by the police in full costume and driving his Batmobile — a sleek black car — vent viral in 2012.

Robinson's car broke down Sunday night as he was driving home from a car show. He stopped the car partially on the fast lane to check what the problem was.

A car then hit his vehicle, which hit him. Robinson was pronounced dead at the scene.

In 2012, Robinson was pulled over for not having a proper license plate, but by the end of the video the officers were seen shaking his hand and taking pictures of him next to the car.

Robinson lived outside Baltimore, and after building and then selling a successful commercial cleaning business, he had enough cash to buy his Batmobile. He then bought the Batman costume for $5,000 and spent $25,000 a year on toys and memorabilia that he handed out to children in hospitals, The Washington Post reported in 2012.

He became obsessed with Batman because of his son who loved the superhero when he was younger. His son sometimes came with him to hospitals dressed as Robin. Many hospitals and charities were calling him up to ask for visits.

Robinson always said the only reason he was doing it was "for the kids."

Correction: The original version of this post reported that Robinson was driving a Lamborghini that broke down. In fact, it was a custom-made vehicle, according to Hagerstown, Maryland police. The error has been corrected.
