Reinforcement Learning for Autonomous Underwater Vehicles via Data-Informed Domain Randomization
Autonomous Underwater Vehicles (AUVs) or underwater vehicle-manipulator systems often have large model uncertainties from degenerated or damaged thrusters, varying payloads, disturbances from currents, etc. Other constraints, such as input dead zones and
