This is pretty amazing.
A self-controlled swimming robot has completed a journey from San Francisco to Australia.
The record-breaking 9,000 nautical mile (16,668km) trip took the PacX Wave Glider just over a year to achieve.
Liquid Robotics, the US company behind the project, collected data about the Pacific Ocean’s temperature, salinity and ecosystem from the drone.
