A team of MIT scientists developed hydrogel-based robots that are virtually invisible under water. A video shows an unsuspecting ryukin goldfish suddenly ensnared in the four arms of a robotic hydrogel claw, produced thanks to 3D printing. To function, these soft robots require a hydraulic connection and a pump, which are not invisible.

The Verge, “Watch this invisible robot grab a fish out of the blue.”

Nature Communications, Hyunwoo Yuk, Shaoting Lin, Chu Ma, Mahdi Takaffoli, Nicolas X. Fang, Xuanhe Zhao, “Hydraulic hydrogel actuators and robots optically and sonically camouflaged in water.”
