In this paper we focus on the application of reinforcement learning to obstacle avoidance in dynamic Environments in wireless sensor networks. A distributed algorithm based on reinforcement learning is developed for sensor networks to guide mobile robot through the dynamic obstacles. The sensor network models the danger of the area under coverage as obstacles, and has the property of adoption o...

modeling and wrench feasible workspace analysis of a spatial cable suspended robots is presented. a six-cable spatial cable robot is used the same as stewart robots. due to slow motion of the robot we suppose the motion as pseudostatic and kinetostatic modeling is performed. various workspaces are defined and the results of simulation are presented on the basis of various workspaces and applied...

– one of the important applications of robots is in material handling and transport of various shaped objects. in cases where an object cannot be directly grasped by the robot gripper, and must be carried by a hook, it may be subject to undesirable swings during transport. this paper presents an analytical method for minimizing the oscillation of a suspended object during transport. this method...

BACKGROUND The particle size and structure of masticated almonds have a significant impact on nutrient release (bioaccessibility) and digestion kinetics. OBJECTIVES The goals of this study were to quantify the effects of mastication on the bioaccessibility of intracellular lipid of almond tissue and examine microstructural characteristics of masticated almonds. DESIGN In a randomized, subje...

Modulation of force during mammalian mastication provides insight into force modulation in rhythmic, cyclic behaviors. This study uses in vivo bone strain data from the mandibular corpus to test two hypotheses regarding bite force modulation during rhythmic mastication in mammals: (1) that bite force is modulated by varying the duration of force production, or (2) that bite force is modulated b...

due to their advantages, omni-directional mobile robots have found many applications especially in robotic soccer competitions. however, omni directional navigation system, omni-vision system and kicking mechanism in such mobile robots have not ever been combined. this situation brings the idea of a robot with no head direction into existence, a comprehensive omni directional mobile robot. such...

The temporomandibular joint (TMJ) is a critical articulation between the mandible and cranium. unique anatomy allows for multifaceted motion unlike any other in human body. bi-convex curvature of bony prominences facilitates compound hinging sliding movement, which are driven by muscles mastication constrained various ligamentous connections surrounding joint. Proper alignment function these st...
