Implementation of Trajectory Planning Algorithms for Track Serving Mobile Robot in ROS 2 Ecosystem

Abstract

In this paper, our goal is to present the autonomous cone placing robot developed at SzéchenyiIstván University (Győr, Hungary) and the main steps and parts of its design and preparation. Within this, rather complex task-sequence, we discuss the logic of software operation (embedded in the ROS 2 ecosystem), the main issues of environmental representation and we focus especially on the trajectory planner part of the entire system. The implemented algorithms-including our own innovative ideas are Dijkstra, A*, Hybrid A*, DWA and Elastic band.
