According to the steering mode of self-propelled modular transporter, the key component of the steering system with electro-hydraulic proportional directional valve was designed. The model of the transporter steering single loop system was established through the method of power bond graph and was simulated. The dynamic characteristics of steering circuit were analyzed. Results indicate that th...
Abstract When a solid body floats at the interface of vibrating liquid bath, motion object generates outwardly propagating surface waves. We here demonstrate that chiral objects on fluid are set into steady rotation, with angular speed and direction rotation controlled by interplay between geometry driving parameters. Scaling laws simplified model wavefield reveal underlying physical mechanism ...
Micron-sized self-propelled (active) particles can be considered as model systems for characterizing more complex biological organisms like swimming bacteria or motile cells. We produce asymmetric microswimmers by soft lithography and study their circular motion on a substrate and near channel boundaries. Our experimental observations are in full agreement with a theory of Brownian dynamics for...
We consider the dynamics of self-propelled particles subject to external torques. Two models for the reorientation of self-propulsion are considered: run-and-tumble particles and active Brownian particles. Using the standard tools of nonequilibrium statistical mechanics we show that the run and tumble particles have a more robust response to torques. This macroscopic signature of the underlying...
