Abstract
En este trabajo se presentan los últimos resultados en investigación en el marco de la tesis Planificación de caminos y
trayectorias de una formación de robots autónomos. La planificación de camino consiste en encontrar un camino continuo
que lleve a un robot desde su posición inicial a su destino, evitando colisiones con su entorno. Basado en el método de
exploración del Algoritmo Genético Simple (AGS) y del algoritmo de búsqueda clásico A*, se propone un algoritmo híbrido
de planificación de caminos para sistemas multirobots. Este algoritmo encuentra los caminos óptimos (o casi- óptimos) libres
de colisiones de una formación de robots desde una configuración inicial a una configuración final teniendo en cuenta la
posibilidad de separación y su posterior reunión. Los resultados de las simulaciones demuestran que el algoritmo es apto para
ser utilizado en entornos complejos con obstáculos y para un sistema mutlirobots
In this work the latest research results are presented within the framework of the thesis Motion planning for a formation of autonomous robots. Path planning is the task of finding a continuous path that will drive the robot from the start to the goal location avoiding collisions with obstacles. Based on the Simple Genetic Algorithm (AGS) exploration method and the classic A* search algorithm, a hybrid path planning algorithm for multirobots systems is proposed. This algorithm finds the optimal (or near-optimal) collision-free paths of a robot formation from an initial configuration to a final configuration, taking into account the possibility of separation and their subsequent reunification (split&merge). The results of the simulations show that the algorithm is suitable for use in complex environments with obstacles and for a multirobots system.
