VideoRay Training U.S. Army Corps of Engineers, Pittsburgh District

A VideoRay PRO 5, an underwater remote operated vehicle (ROV), is staged for display during a training event for the U.S. Army Corps of Engineers Pittsburgh District at a lock and dam facility on the Allegheny River in Natrona, Pennsylvania, Sept. 22, 2021. This ROV model is new to the Pittsburgh District, equipped with a high-definition video and photo camera, a multibeam sonar, a claw that can rotate and grab objects, and a motor that is twice as powerful as the previous version to pilot through stronger currents.
