Here, we show that micro-swimmers can form a concealed swarm through synergistic cooperation in suppressing one another’s disturbing flows. We then demonstrate how such a concealed swarm can actively gather around a favorite spot, point toward a target, or track a desired trajectory in space, while minimally disturbing the ambient fluid. Our findings provide a clear road map to control and lead flocks of swimming micro-robots in stealth vs fast modes, tuned through their active collaboration in minimally disturbing the host medium.

隐秘的运动和隐藏的游泳微型机器人群

在这里，我们表明微型游泳者可以通过协同合作来抑制彼此的干扰流，从而形成一个隐蔽的群体。然后，我们展示了这样一个隐藏的群体如何主动聚集在喜欢的地点周围、指向目标或在空间中跟踪所需的轨迹，同时最大限度地减少对环境流体的干扰。我们的研究结果提供了一个清晰的路线图，以在隐身与快速模式下控制和引导游泳微型机器人群，通过他们的积极合作进行调整，以最大限度地减少对宿主介质的干扰。
