Issues on UGV Optimal Motion Planning and Obstacle Avoidance
نویسندگان
چکیده
We present two different optimal control problem formulations that can be used to solve various trajectory planning scenarios of an Unmanned Ground Vehicle (UGV). It is less a study of trajectory planning than it is an analysis of the optimal control planning method itself. Numerous issues regarding vehicle modeling, obstacle modeling and computational complexity are discussed. The results and recommendations presented in this work are quite simple concepts, but have not been covered in the literature of trajectory planning to the knowledge of the co-authors. Simulation results illustrate successful implementation in various scenarios.

متن کاملOptimal Trajectory Planning of a Mobile Robot with Spatial Manipulator For Spatial Obstacle Avoidance
Mobile robots that consist of a mobile platform with one or many manipulators mounted on it are of great interest in a number of applications. Combination of platform and manipulator causes robot operates in extended work space. The analysis of these systems includes kinematics redundancy that makes more complicated problem. However, it gives more feasibility to robotic systems because of the e...
متن کاملObstacle Avoidance of mobile robot using PSO based Neuro Fuzzy Technique
Navigation and obstacle avoidance are very important issues for the successful use of an autonomous mobile robot. To allow the robot to move between its current and final configurations without any collision within the surrounding environment, motion planning needs much treatment. Thus to generate collision free path it should have proper motion planning as well as obstacle avoidance scheme. Th...
متن کاملWavefront Propagation and Fuzzy Based Autonomous Navigation
Path planning and obstacle avoidance are the two major issues in any navigation system. Wavefront propagation algorithm, as a good path planner, can be used to determine an optimal path. Obstacle avoidance can be achieved using possibility theory. Combining these two functions enable a robot to autonomously navigate to its destination. This paper presents the approach and results in implementin...
متن کاملOptimization Based Obstacle Avoidance
Based on a non-linear single track model which describes the dynamics of vehicle, an optimal path planning strategy is developed. Real time optimization is used to generate reference control values to allow leading the vehicle alongside a calculated lane which is optimal for different objectives such as energy consumption, run time, safety or comfort characteristics. Strict mathematic formulati...
