The focus of this chapter is self-propelled objects, which indicate nonlinear behaviours, such as oscillation, synchronization, bifurcation and pattern formation, with the aim of enhancing their autonomy. The driving force of the objects on water is the difference in the surface tension. Such characteristic features of motion are theoretically and experimentally designed considering nonlinear dynamics based on a reaction–diffusion system and the difference in the surface tension acting as the driving force, depending on the chemical structures.
