James Gosling -- the so-called "father of Java" -- left Google on Tuesday to join a company that is looking to scatter thousands of robots around the Earth's oceans. Gosling will become chief software architect for Sunnyvale startup Liquid Robotics, a 4-year-old company that places 7-foot-long robots resembling surfboards in the ocean to collect and transmit data for a variety of uses. Called Wave Gliders, the devices are powered by wave energy, with the constant up-and-down motion providing energy that pulls the robots through the ocean.
