Last November, Liquid Robotics launched 4 Wave Gliders from San Francisco, CA. After a 9,000 mile trek, two arrived in Japan and two in Australia. One of them, Papa Mua, broke a Guinness World Record for the longest distance traveled by a robot. The project was designed to show how these water bots can gather data and travel at the same time.
A second purpose for the trek is to draw attention to a $50,000 research grant for the roboticist that can come up with the best way to utilize that knowledge. Head over to their site to see what the five finalists have to offer.
