So idea is to use small device that uses AI to untangle trapped seabirds, fishes and all kinds of animals that get stuck in abandoned fishing nets in the oceans and seas, so this device would have underwater camera and some cutting scissors or blade and whole thing is connected by wire to a laptop (above water, in case you wonder:)), it should be able to do most of the things without input from crew, so it may need an AI that is capable of visual recognition and control of simplest movements. Net remains will then be compressed and sent to recycling.

So what models would be best for this? And are there opensource ones?

So the way training will work I guess would involve bathtub and rubber ducks, stuck in the net in thousands different ways, so i think has to be ways to give it feedback too. So what model can be ok for start?
