But in case of active moving obstacle, many components and information need to process since their moving trace should be considered in real time. This paper mobile robot＇s driving algorithm of unknown dynamic envirormaent in order to drive intelligently to destination using ultrasonic and Global Positional Systern （GPS）. Sensors adjusted the placement dependment on driving of robot, and the robot plans the evasion method according to obstacle which are detected by sensors. The robot saves GPS coordinate of complex obstacle. If there are many repeated driving, robot creates new obstacles to the hr, ation by itself. And then it drives to the destination resolving a large range of local minirmnn point If it needs an intelligent circtmtantial decision, a proposed algorithm is suited for effective obstacle avoidance and arrival at the destination by performing simulations.展开更多

Its construction requires prolonged effort and a comprehensive grasp of modernity, the laws of social development and the overall logic of social development, as well as an all-around readjustment of concepts, institutions and behaviors. Within the concrete and historical unity of rights and responsibilities, ＂the unity of limited global rights and limited global responsibilities＂ is an important principle for constructing global development equity. Declarations that China is practicing neo-colonialism are in fact inherently associated with Eurocentrism. The peaceful, joint and comprehensive development of China and other developing countries and China＇s historical advancement of global development equity are practical refutations of such assertions.展开更多

We present a two-part hierarchical control method that can guarantee platoon stability with minimal fuel consumption. The first part vehicle controller is derived in the context of receding horizon optimal control by constructing and solving an optimization problem of overall fuel consumption. The Second part platoon controller is a complementation of the first part, which is given on the basis of platoon stability analysis. The effectiveness of the presented platoon control method is demonstrated by both numerical simulations and experiments with laboratory-scale Arduino cars.展开更多
