After the sonar, the thickness gauge, the sediment/water samplers, the physico-chemical probes and the acoustic positioning system, Subsea Tech just developed a 2 functions manipulator (wrist rotation-gripper open/close) compatible with its range of remotely operated vehicles : Observer, Guardian, Sentinel and Narval.
It is mounted under the vehicle and controlled through the pilot console. The manipulator can lift up to 200 g on ROV vertical thrust and several kilos pulling the ROV by its umbilical. From shell to aluminum can, the Manipulator combined with the ROV video cameras is an essential tool for grabbing underwater objects with precision.
