We will show experimental results of the behavior of micro-droplet robots generated and controlled by defocused laser beams on a gold nanoparticle-dispersed substrate, which change their shape in unintended ways in response to the environment of the substrate. We also discuss that this behavior is not artificially controlled, but is caused by the interaction between the controlled object (droplet) and the environment (substrate), which is an important property for the droplet to adapt biologically and reflexively to the unknown environment and maintain its survival.
