Meet the Aquabotix SwarmDiver: a micro under/water surface vehicle that can be controlled as a coordinated swarm by one human operator. These machines weigh only 1.7kg, measuring 75cm long. They can dive to a depth of 50 meters.
SwarmDivers feature accurate temperature and pressure sensors. They can be deployed in groups for data gathering. A simple control interface is available to allow the operator to control an entire fleet easily.
