Certain tourism attractions operate large, enclosed underwater environments that require frequent cleaning to maintain visibility, hygiene and optimal guest experiences. These environments may house delicate marine creatures which may be harmed by water turbulence or physical contact with humans who enter the habitat. Equally, humans may be harmed if direct skin is exposed to some of these creatures. Current cleaning approaches rely heavily on manual scuba diving, which is labour-intensive, constrictive, and could be disruptive for both animals and staff. Also, traditional underwater maintenance tools are often limited in their ability to achieve desired cleanliness levels of the habitats.
The challenge is to develop an automated or semi-automated underwater cleaning solutions that can operate safely in confined, low-visibility environments, minimise disturbance to marine life, and reduce reliance on human divers. Solutions may involve robotics, tethered systems, advanced sensing (environmental state), precision control (navigation around the habitat), locomotion without excessive water turbulence, or novel cleaning mechanisms, but must prioritise safety, effectiveness, reliability and animal welfare.
