These underwater fish vehicles are helping to keep oceans clean. The robotic fish are keeping tabs on the water's quality by detecting hot spots with higher PH levels, which indicates a higher level of acidity. The water's acidity can impact the survival of marine life, as studies show that the higher PH levels can result in stress and disease in fish, often altering their survival instincts, making them more susceptible to predators.
Looking to amend this issue, in an efficient, and non-disturbing way, researchers at the University of Florence created a fish-like underwater vehicle, which mimics the way underwater creatures swim.
The research team behind this design hopes the robot fish system provides early indications of environmental change, which will ideally result in the increased wellness of aqua-culture.
