Liquid Robotics’ product, a Wave Glider, is about the size of a surfboard. Using a wave-based propulsion system and two solar panels to fuel its computers, the robots travel slowly over the ocean, recording data. The sensor data is crunched onboard by low-power cellphone chips, and then shipped by satellite or cellphone to big onshore computers that do complex analysis.
