Soft robot mimics lionfish’s graceful movement with flow batteries and hydraulic fluids
It has electrolyte for blood, two peristaltic pumps as hearts and several flow battery stomachs – this is the robotic lionfish built by US researchers. Just like the real thing, the robofish swims by moving its tail and can fan its pectoral fins – though luckily it isn’t venomous like it’s biological counterpart.
