Liquid Robotics have a growing fleet of autonomous vehicles that rove the ocean collecting data from a variety of on board sensors and uploading it to the cloud. The robots have a pile of satellite uplink/GSM/WiMax communication gear and redundant GPS units. For example, one is a set of robots patrolling the ocean around the Macondo well in the Gulf of Mexico monitoring water chemistry. These craft harvest energy from the waves for propulsion and can stay at sea for a very long time. They can cross oceans…. Slowly. Filmed at JFokus 2013.
