This project is the first endeavour of BREED HKU, HKU’s first bio-inspired robotics organisation. RoboFish is our very own robotic fish, controlled by a raspberry pi and powered by a battery, aimed at helping us learn more about underwater biomechanics. Not only does the fish have a high speed potential, but the project also involves the study of how fish movements are affected by different variables such as turbulence and drag. This targets the analysis of marine biology and ecosystems. Our model has many applications for research and development in the academic world, such as surveillance systems and sea exploration.
