WebNov 15, 2024 · Related to the latter, gliders have learned to navigate in a turbulent flow [17,18] and microswimmers learned a complex flow field [19][20] [21] [22][23][24]. In experiments, reinforcement ... WebMay 9, 2024 · Efficient navigation in complex flows is of crucial importance for robotic applications. This work presents a numerical study of the point-to-point navigation of a fish-like swimmer in a time-varying vortical flow with a hybrid method of deep reinforcement learning (DRL) and immersed boundary–lattice Boltzmann method (IB-LBM). The vortical …
Flow Navigation by Smart Microswimmers via …
WebApr 22, 2024 · Navigation of micro-swimmers in steady flow: the importance of symmetries. Marine microorganisms must cope with complex flow patterns and even turbulence as they navigate the ocean. To survive they must avoid predation and find efficient energy sources. A major difficulty in analysing possible survival strategies is that … WebJan 30, 2024 · Flow Navigation by Smart Microswimmers via Reinforcement Learning. Smart active particles can acquire some limited knowledge of the fluid environment from simple mechanical cues and exert a control on their preferred steering direction. Their goal is to learn the best way to navigate by exploiting the underlying flow whenever possible. sigmix: decoding superimposed signals for iot
