چکیده
Aimed at the difficulty of path planning resulting from variable configuration wheel-legged robot for future deep space explorations, this paper proposes a algorithm based on Theta* and Timed Elastic Band (TEB) algorithm. Firstly, structure is briefly introduced, workspace single leg analyzed. Secondly, method to judge complete obstacles incomplete according height proposed alongside search virtual obstacles, generate grid map wheel body, respectively. By dividing into split body path. The can be still simplified as point by searching obstacle, which avoids shape. Then, we hierarchical multiple optimization algorithms TEB optimized smoothed effectively obtain shorter length higher safety. On that basis, simulated Matlab. results simulations show in plan using configurations different types obstacles. path-planning has broad prospect exploration.

Robot Path Planning Using Cellular Automata and Genetic Algorithm
In path planning Problems, a complete description of robot geometry, environments and obstacle are presented; the main goal is routing, moving from source to destination, without dealing with obstacles. Also, the existing route should be optimal. The definition of optimality in routing is the same as minimizing the route, in other words, the best possible route to reach the destination. In most...
متن کاملPSO-Based Path Planning Algorithm for Humanoid Robots Considering Safety
In this paper we introduce an improvement in the path planning algorithm for the humanoid soccer playing robot which uses Ferguson splines and PSO (Particle Swarm Optimization). The objective of the algorithm is to find a path through other playing robots to the ball, which should be as short as possible and also safe enough. Ferguson splines create preliminary paths using random generated para...
متن کاملSampling-based A* algorithm for robot path-planning
This paper presents a generalization of the classic A* algorithm to the domain of sampling-based motion-planning. The root assumptions of the A* algorithm are examined and reformulated in a manner that enables a direct use of the search strategy as the driving force behind the generation of new samples in a motion-graph. Formal analysis is presented to show probabilistic completeness and conver...
متن کاملMemetic Algorithm Based Path Planning for a Mobile Robot
In this paper, the problem of finding the optimal collision free path for a mobile robot, the path planning problem, is solved using an advanced evolutionary algorithm called memetic algorithm. What is new in this work is a novel representation of solutions for evolutionary algorithms that is efficient, simple and also compatible with memetic algorithm. The new representation makes it possible ...
