a Schematic of JO-robot. The top surface is superhydrophobic with low droplet adhesion and the bottom surface is hydrophobic with high droplet adhesion. With the help of capillary force, the JO-robot can wrap water droplet and transport droplet directionally by magnetically controlled tumbling. b The corresponding images of directional tumbling, wrapping droplet and directional transport of droplet by JO-robot. c–f Versatile droplet manipulation based on JO-robot. c The JO-robot enables daughter droplet dispensing under magnetic field and capillary force. d The wrapped droplet can be released by the JO-robot by squeezing and pushing. e The JO-robot can stir droplet under the action of the rotating magnetic field and f it can also realize photothermal stirring by NIR laser irradiation. All scale bars are 2 mm.
