Underwater navigation (USBL)
USBL is a widely used tracking system for underwater. The system consists of a transceiver mounted on the vessel, and a transponder mounted on Boxfish ROV. Using the USBL, the position of the ROV is found relative to the vessel’s GPS coordinates. Learn more
Doppler Velocity Log (DVL)
DVL is an acoustic sensor that estimates velocity relative to the sea bottom. Because of the acoustic nature of this technology, it operates well in low visibility. The estimated velocities are converted … more into an XYZ coordinate system relative to the sea bottom. Learn more
Multibeam Imaging Sonar
Imaging sonars are great for navigation while moving and for locating stationary or moving objects. Boxfish ROV has the option of integrating the Blueprint Subsea Oculus dual-frequency sonars. These sonars have 512 beams and operate at various frequencies between 750 kHz and 2.1 MHz with 60 degree to 130 degree fields of view. Distances to 120m and resolution down to 2.5mm are possible depending on frequency used. Learn more
Profiling sonar
Profiling sonars are for ultra-high resolution underwater 3D reconstruction and profiling for site surveying or rendering. They operate similar to a line scanner that requires slow and controllable movements to capture the data. The high manoeuvrability and the active stabilisation of the Boxfish ROV are necessary to get reliable and accurate 3D reconstructions with this technology.
Laser Scalers
It is often required to do simple length measurements underwater for understanding the scale of the object in view. Boxfish Robotics can add two or four laser scalers to the ROV that facilitate it. Photogrammetry is another application that can take advantage of laser scalers. The 3D model built by photogrammetry techniques does not have the correct scale. Having the known length of laser scalars helps to correctly scale 3D models reconstructed using photogrammetry.
Photogrammetry
Photogrammetry is the process of making a 3D model of an environment using a single camera. During the process, the structure of the scene and the position of the ROV are found simultaneously. Boxfish ROV provides high quality and stabilised videos with homogeneous lighting that are very suitable to be used for photogrammetry purposes. Learn more
Manipulator/Grabber
The exceptional manoeuvrability of Boxfish ROV enables the pilot to carry out a wide range of operations with even the most basic grabber. More sophisticated grabbers add additional functionality for more complex tasks. Learn more
Rotary Cleaning Brush
It is often necessary to remove marine growth and dirt from submerged assets to facilitate inspection and testing tasks. The Boxfish ROV rotary cleaning brush enables operators to clean a range of … more surface materials, including concrete and metal. Learn more
Environmental Sensors
Boxfish Alpha support a large payload allowing marine scientists to capture environmental data along with the video. Available sensors include miniCTD, chlorophyll, turbidity, fluorometer, pH and hydrophone.
Field Fast Charger
Recharge the Alpha ROV in the field in as fast as 45 minutes with the Boxfish 40/60A AC Charger. This field fast charger is enclosed in a waterproof IP67 case, and allow … more to recharge the ROV if needed while you are moving between sites.
