A low cost USV for aqua farm inspection [PDF]

2016 Techno-Ocean (Techno-Ocean), 2016
This paper describes the rapid prototyping of a low cost remotely controlled unmanned surface vessel (USV) intended for inspection of aqua farms. There is an increased focus on inspection of ocean-based aqua farms due to three major challenges: escaping fish, sea lice, and algae.
