The beautiful oceans that cover three-quarters of our planet are home to some of our most valuable natural resources. However, while our knowledge of outer space is quite wide, the same cannot be said about the deep waters, thanks to the fact that any attempts to monitor them have either been too awkward or too expensive. Now, California-based Liquid Robotics has come up with an invention that is both economical and easily used across the waters.
Called Wave Glides, the autonomous robot that resembles a surfboard consists of two interconnected sections 一 on the surface is a glider （滑翔机）^tted with solar panels, battery and sensors. Right below underwater is a navigation （航行）glider.
The robot travels at a snail's pace gathering data. This data is quickly sorted by its solar-powered computer chips and then sent ashore for analysis. This robot contains no battery that needs recharging. It is a zero emission （排放）device that uses wave energy to push itself forward.
   The company is working towards making the robot even more autonomous than it currently is. As it now stands, while the robot can sense a danger such as a ship or a shark, it does not have the ability to move away. Liquid Robotics wants to change that and program the robot so that it has the ability to move away from danger.
   To encourage the general public to get involved with the informative data collected by Wave Glider, the company is planning to launch four of the robots on a yearlong trip across the Pacific. Two will head for Tokyo and two for Sydney. All the data they collect will be posted online and the person who comes up with the most innovative interpretation will be awarded a prize.
