Energy-Saving Vortex Phase Matching in Fish Schools and Robots

Energy-Saving Vortex Phase Matching in Fish Schools and Robots

Fish swim in schools not only for protection but also to save energy by coordinating their movements to interact with water vortices. This natural behavior, vortex phase matching, is observed in both fish and fishlike robots, reducing their energy use during swimming.

    魚は専門じゃないけど学会等で fish schooling の話はよく見かける。古くは 1973 Weihs https://t.co/iyQcyZXazx から（？）あり、最近だとこういうのとか https://t.co/x4A9212Mkn ちょっと動画の school だと左右間隔が広すぎて抗力低減はあまりないんではという印象もあるけど、実際どうなんだろ… https://t.co/Gbytofw4A6

Abstract Synopsis

  • The study explores how fish and fishlike robots can save energy while swimming together by coordinating their movements to interact with the vortices (swirling water flows) produced by their neighbors, a strategy called vortex phase matching.
  • Researchers created robot models to measure energy use and found that fish can benefit hydrodynamically if they adjust their tailbeat timing based on their position relative to others, with this timing difference varying linearly with distance.
  • Experiments with real fish showed they naturally use vortex phase matching without needing their vision or lateral line systems, suggesting this is a common and energy-saving strategy in schooling fish.]
