This robotic fish was designed to test the water health at fish farms. Developed by researchers from the University of Florence, the Technical University of Madrid and the Center for Automation and Robotics, the biology-inspired robot fish moves just like the real thing in order to monitor pH levels in water.
The autonomous aquatic robots are equipped with sensors to measure pH levels and will change its swimming patterns to indicate where dangerously acidic or poisonous areas are. The bio-mimetic prototype is 30 cm long and is made out of a "shape memory alloy" to mimic the flexibility of a fish's backbone.
This method to monitor water health is a way to better meet the demand and supply for food as the world's population grows.
