Robots Attempt Record Breaking Pacific Ocean Voyage
Four robots have set out on an epic 33,000 nautical mile (66,000km) journey across the Pacific Ocean. Created by US firm Liquid Robotics, the four are aiming to set the record for the longest distance at sea travelled by an unmanned craft. Throughout their journey the robots will gather lots of data about the composition and quality of sea water. The journey is expected to take about 300 days, and is designed to inspire researchers to study ocean health.
