英文摘要: A robot is a comprehensive system collecting environment sensing, localization, controlling and decision-making, etc. It is wildly used in all walks of life, which makes it a hot issue in both academic and industrial area. The safety and reliability of robots system should be highly ensured, in case of huge personal injuries or property damages caused by system failure. Formal methods are efficient means to make sure of the correctness and reliability of the system. The time constraints for robotic missions can be well expressed in temporal logic. In this project, we will focus on the motion planning problem of modern mobile robots in complicated environment. Model checking, one of formal methods, is adopted here. Design and implementation of the robot control software will be achieved for motion planning based on probabilitic timed automata. To check the effect of our approach, an experiment environment will be established as well. The difficulty of the project lies in the formalization of dynamic environment, motion space and kinematic models. We will do the research from the following three aspects: (1) formal modeling of environment, robots behavior and requirement specifications, (2) the generation of motion trajectories in dynamic environment, (3) continuous control input generation under discrete trajecto
