Gosling is admiral of a fleet of robotic marine drones

By Roger Smith

Father of Java is now Liquid Robotics' chief software architect

I learned James Gosling, the creator of the Java language, is now the admiral of a fleet of water-borne drones from Mike Duigou last Thursday at the Java Hub in the JavaOne Exhibit hall. Gosling is the chief software architect for Sunnyvale-based Liquid Robotics, a 8-year-old company that uses self-propelled 7-foot-long marine robotic drones that look like surfboards to collect and transmit oceanic data for a variety of uses. Duigou told me that he was brought aboard by Gosling as Senior Software Engineer when he joined the company in 2011.

Called Wave Gliders, the drone are powered by wave energy, with the constant up-and-down motion providing energy that pulls the robots through the ocean. Duigou gave me a hand-on tour of the USS Gosling, a test Wave Glider on display in the Hub. He explained the Wave Glider is made of two parts: the surfboard-sized float that stays on the surface; and the sub that has wings and hangs 3-9 meters below the float on an umbilical tether. Because of the separation, the float experiences more wave motion than the sub. This difference allows wave energy to be harvested to for propulsion.

The Wave Glider is equipped with several computers for navigation and payload control, satellite communication systems, and ocean sensors that do things like measure weather, sea conditions, water quality and chemistry, animal life and water currents. Acoustic microphones and arrays on the Wave Glider have also been use to record passing ships and the vocalizations of whales and other mammals (an early use case of the company's technology).

The power needed to operate the sensors and computers is provided by solar panels, which are used to recharge lithium-ion batteries. Individual Wave Glider can be programmed for autonomous operation, or it can be steered by a remote pilot over the Internet. Continuous, near real time, communication is provided via satellite, cellular phone or radio links for piloting and data transmission.

All the Wave Glider computing power is Linux- and Java-based and includes a Hadoop cluster on the backend used to analyze the large data sets the devices collect, either individually or in groups. Duigou explained that the Wave Gliders can also be programmed to operate as a drone swarm. "For example, you can set up a fence around a marine protected area like Monterey Bay and give them all the goal of defending the border and reporting intruders. The robots can figure out who goes where."

Robots, NetBeans IDE, and Raspberry Pi with James Gosling

James Gosling is now chief software architect of the Wave Glider, the flagship product at Liquid Robotics. The Wave Glider is a self-propelled, autonomous marine robot that collects and transmits ocean data. The Wave Glider will be on display exclusively at the Java Hub in the JavaOne exhibit hall during the entire conference. 

Since Gosling started at Liquid Robotics, he has re-architected the onboard software and refined a data-as-a-service cloud to provide direct, real-time access to ocean information. Java, which he invented, has played an increasing role in ocean data transmission and analysis.  

“Being able to debug and profile robots out at sea is a truly life-altering experience,” Gosling explains. He uses a set of tools—consisting of editors, debuggers, and profilers—that are part of the NetBeans IDE. At the JavaOne 2014 NetBeans Community Day, he will present the session “James Gosling, Robots, the Raspberry Pi, and Small Devices” [UGF8907] on Sunday, September 28. He will also present “Debugging and Profiling Robots with James Gosling” [CON6699] on Wednesday, October 1. Geertjan Wielenga, Mark Heckler, José Pereda, Johannes Weigend, Shai Almog and Jens Deters will join him to discuss those two topics. 

Join him as he closes out the JavaOne Community Keynote with a fun, historical perspective of the genesis of Java, and a T-shirt toss! The Community Keynote will be held in the Marriott Marquis, Salon 7/8/9, on Thursday, October 2, 2014
