There's a robot that's been continuously running since 1996 - Apparently.
In 1996, a robot called "The Mechanical Man" was built by a Japanese engineer, and it has been functioning non-stop for over 26 years. The robot's sole purpose is to play a continuous loop of Beethoven's 5th Symphony on a piano. According to Guinness World Records, it holds the record for the longest-running robot in continuous operation. Despite being over a quarter-century old, the robot still plays its tune with precision and accuracy, a testament to its well-designed mechanical system.
