Maritime Robotics Otter USV is the ultimate hydrographic survey tool for mapping sheltered and enclosed waters from the surface. As the smallest member of the Maritime Robotics USV family, it has a footprint of 200 x 108 x 106.5cm (78.7″ x 42.5″ x 41.9″), allowing the Otter USV to fit into any small cargo van for convenient transportation to and from survey sites. When fully assembled, it weighs 65kg, but it can be disassembled into parts weighing less than 20 kg, making it easy for a single operator to deploy and navigate.

Despite its size, the Otter has high endurance, capable of operating for up to 20 hours at 2kn. It is equipped with electric thrusters powered by up to four powerful and easily interchangeable battery packs. These battery packs are built with readily available components and spare parts can be easily accessed worldwide.

Operating the Otter is done through a graphical user interface: Maritime Robotics’ vehicle control station (VCS) or a mobile phone app. The app provides manual joystick-like control, while the VCS offers various control modes, including course and speed control, heading control, and waypoint control. It also includes pre-programmed templates for common surveying patterns in controlled waters, such as lawnmower surveys.

The VCS provides live monitoring of sensor data quality parameters and visualisation of actual data. These sensor parameters can also be adjusted within the VCS.
