Automatic net inspection project grant from FHF

Mohn Technology is pleased to receive 5MNOK grant from FHF – the Norwegian Seafood Research Fund to develop a new autonomous net inspection drone for the aquaculture industry.

The drone will be a new tool to help fish farmers inspect their net pens more often and effective to a lower cost than diving and conventional ROV based inspection. An autonomous underwater vehicle (AUV) is a very complex product, that will demand a lot from our developer team. Mechanical and cybernetics has to work hand in hand in order for the AUV to work efficiently and effective under difficult conditions.

The AUV will be battery powered without umbilical, to reduce the risk of entanglement in existing equipment in the facility. Navigation will be based on a mixture of machine vision, compass and IMUs (Inertial Measurement Unit). The customer will gain access to reports and status via a web portal.

We are really looking forward to start on this project, as it is both very interesting and fits our company profile well!

Many thanks to FHF for the trust and support!

Autonomous wall / net tracking achieved

Mohn Technolgy is working on an autonomous net cleaning system. Early pool testing and development is done on a simplified prototype that has an umbilical for live tracking of the process. The autonomous properties can be transferred to future prototype versions even though they will differ greatly from this early version. Both the prototype and future vessel is battery powered.

The automatic wall tracking is possible by the use of an accurate IMU (Inertial measurement unit), a stereo camera and some clever programming.
