Bots of the sea

Robots are also making a mark in the water. Pictured here is the Wave Glider from Liquid Robotics. It is a robot able to operate autonomously for months at a time at sea, powered by solar panels and the motion of waves. The device is being used to gather information about the oceans, such as the acoustic impact on mammals, or for defense and security. Among the employees at Liquid Robotics is James Gosling, one of the inventors of Java and the former chief technology officer of Sun Microsystems.
