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.
