What did Tesla call his remote-controlled boat demonstrated in 1898? Tesla called it the Teleautomaton. He demonstrated the small vessel at an electrical exhibition at Madison Square Garden in New York, showing that it could be controlled wirelessly from a distance.

The boat used radio signals and a coherer-based receiving system to activate its controls. Tesla operated its movements remotely, an astonishing demonstration at a time when radio technology was still developing and practical electronic remote control was unknown to the public. The device is often described as an early radio-controlled vehicle and a precursor to robotics.

Tesla believed the invention could have military uses and tried to interest the United States military in a radio-controlled torpedo. Officials showed little interest, partly because the technology was difficult for them to understand and trust. “Torpedo” is therefore a plausible mix-up: it describes Tesla's proposed application, not the name he gave the demonstrated boat. Tesla later used the related term “teleautomatics” for remote-control systems.
