When underwater robots land on the seafloor, inspect shipwrecks, or dig into sandy areas, they often stir up clouds of sediment that block their cameras. In many cases, operators have no choice but to wait for the water to clear before […] The post New sonar-camera system could help underwater robots navigate in near-zero visibility appeared first on Knowridge Science Report .
