Researchers at Norway's SINTEF institute are designing an underwater robot to autonomously inspect fish farms.

CageReporter uses a proprietary underwater positioning system and a three-dimensional computer-vision system, to check the conditions of the netting and the fish.

The robot also employs artificial intelligence-based algorithms to observe fish's behavior, tweaking its movements to avoid disturbing them.

CageReporter utilizes onboard sensors to measure the water's temperature, oxygen levels, and light levels; if it detects any problems, the robot communicates its location to a base station via ultrasound pulses.

SINTEF's Eleni Kelasidi said, "The technology gives us incredibly precise and important information on, for example, the fish’s health and the quality of the water in real time."
