Abstract :
Microrobots made of light-absorbing hydrogel material were actuated by optically induced thermocapillary flow and move at up to 700 μm/s. The micro-assembly capabilities of the microrobots were demonstrated by assembling polystyrene beads and yeast cells into various patterns on standard glass microscope slides. Two microrobots operating independently in parallel were also used to assemble micro-hydrogel structures.
