London, Mar.15 (ANI): Four robots have set a new distance world record, swimming more than 3,200 nautical miles or 5,926 kilometers across the Pacific Ocean.
According to the BBC, the drones are taking part in a project to gather data about the composition and quality of seawater.
Built by US-firm Liquid Robotics, the PacX Wave Gliders are expected to cover 9,000 nautical miles or 16,668 kilometers by their journey's end.
The first leg of their voyage from San Francisco to Hawaii took four months.
The robots are designed to reach previously inaccessible areas of the ocean and gather data on how acidic the water has become and the shrinking size of fish stocks.
The previous Guinness World Record for the longest distance covered at sea by an unmanned device was 2,500 nautical miles or 4,630 kilometers. (ANI)
