In the past few years, we have covered plenty of robotic fish that can be used for research and other tasks. Maryland researchers are developing a robotic submarine that looks and behaves exactly like a fish. It is made of rubber and uses sensor nodes to replicate the lateral line system.
An electric motor attached to a momentum wheel is used to enable to robot to move like a real fish. Such robots can be used to collect samples to analyze water quality.
