We explore how a technique called Floquet engineering can be used to create and control special three-atom bound states, known as triplons, in systems made of Rydberg atoms. Building on a known method (the WAHUHA protocol), we develop a theoretical model that describes how these triplons behave when the system is driven with periodic pulses. Under certain conditions, the system nearly preserves a quantity called magnetization, which helps keep these bound states stable. We study how triplons move across different atomic setups and show that their motion becomes more efficient when atoms interact over longer distances or in a coordinated way. Our predictions closely match numerical simulations, suggesting that these effects could be tested in current experiments. Finally, we show that in more complex geometries, special types of atomic interactions can protect triplon transport from disruptive effects. This work offers a roadmap for observing new types of quantum particles in programmable systems and contributes to our understanding of how complex quantum systems behave far from equilibrium.
