Static Obstacles Avoidance of Autonomous Mobile Robots Based on Limit Cycle Approach

Résumé

Autonomous robot navigation is the subject of research in many disciplines. In this paper, we discuss the path planning method for obstacle avoidance based on the limit cycle, which has been shown to be effective in both static and dynamic environments. We focus the control architecture known as Limit Cycle, which generates robot trajectories defined by differential equations with proven stability through a Lyapunov function. This approach uses cylindrical bounding boxes around objects in the environment and implements reactive rules to avoid obstacles while respecting safety distances and avoiding deadlocks, local minima, and oscillations. An extension of this method, Parallel Elliptic Limit-Cycle, is also implemented, which is characterized by elliptic bounding boxes rather than cylindrical ones. Finally, results are provided to illustrate the effectiveness and merits of the proposed method for autonomous path planning.

Introduction Autonomous systems [1] have become a topic of growing interest for researchers and tech companies in recent decades driven by advancements in technologies such as machine learning deep learning [2] control theory [3] computer vision [4] and signal processing. The goal of autonomous systems is to provide safer cheaper and more convenient transportation. They are equipped with functional modules such as perception prediction vehicle to vehicle communication [5] planning [6] and control to achieve this goal. Navigation is the most critical factor for autonomous systems as it involves determining the system's position and planning a safe collision- free path towards the destination in such an environment with critical conditions like wind rain snow… Sign in to Continue Reading IEEE Keywords Navigation Limit-cycles Differential equations System recovery Trajectory Safety Mobile robots path planning obstacle avoidance limit-cycle elliptic limit-cycle mobile robotics
