Oscar Curet, Ph.D.,: and other researchers reinforced learning for navigation and coordination of bioinspired underwater vehicles in close formation - “A School of Robotic Fish.” The aim is to investigate optimal control mechanisms for robots that use fin-based propulsion. The goal is to implement an autonomous controller that would allow the robotic swimmer to perform high-level tasks such as station-keeping, trajectory-following or performing collaborative tasks in groups, especially in the presence of external disturbances. The novel aspect of the ongoing work is the ability of the robotic swimmer (and eventually, of swarms) to take decisions completely autonomously in order to attain a specified high-level goal. The range of potential applications include long-term environmental monitoring, deep water observation of aquatic animals, surveillance for coastal protection, and most-importantly, underwater search-and-rescue operations. The biggest benefit of using an autonomous controller is that individuals as well as swarms would be able to respond to unfamiliar situations and unexpected environmental disturbances. Autonomy is crucial since it may not be feasible for a human to monitor the robotic devices 24x7, or the time-delay in communication may be significant as is the case for underwater communication. Curet is an assistant professor in the department of Ocean and Mechanical Engineering in the College of Engineering and Computer Science.
