A question that many researchers in social robotics are addressing is how to create more human-like behaviour robots make the collaboration between a human and robot intuitive partner. In order develop collaborative robotic system, however, must first be better understood. Human something we all familiar with, however not much known about it from kinematic standpoint. One dynamic hasn’t been re...

Compared with the space fixed feature of traditional wireless sensor network (WSN), mobile WSN has better robustness and adaptability in unknown environment, so that it is always applied in the research of target tracking. In order to reach the target, the nodes group should find a self-adaptive method to avoid the obstacles together in their moving directions. Previous methods, which were base...

This paper presents a general description for obstacle avoidance algorithms which can also describe the obstacle avoidance style(walking habit) of moving objects (human beings).A complex sliding mode based obstacle avoidance is presented as a test method, which is learned and modeled by the above mentioned general description. The paper presents simulation results of the sliding mode based navi...

In this paper, we are concerned with the identification of complex obstacles from the scattering data for the acoustic problem. The complex obstacle is characterized by its shape and the boundary values of the impedance coefficient. We establish pointwise formulas which can be used to reconstruct the shape of the obstacle and give explicitly the values of the surface impedance as a function of ...

This study explored the effect of porosity and installation angle, thickness (dimension) and second layer of permeable obstacles on density current control and trapping in the laboratory. For this purpose, an insoluble suspended polymer and two types of groove and cavity obstacles made from plexiglass sheets were selected. The experiments were conducted with two different concentrations, five d...
