The Otter autonomous underwater vehicle is the ultimate hydrographic survey equipment tool for mapping of sheltered and also enclosed waters. With tight integration between the on-board control system of the Otter that enables autonomy and the multibeam echo-sounder for the hydrographic survey equipment, a bathymetric survey can be executed with a simple, streamlined workflow. The Maritime Robotics – Otter autonomous underwater vehicle comes with a laptop providing the Vehicle Control Station, which allows live monitoring of sensor data quality parameters and also visualisation of data coverage in the same graphical user interface.
