Performance analysis of hybrid AMR system with bypassing capability

Abstract

Recently, the adoption of Autonomous Mobile Robot (AMR) systems, which are capable of autonomous navigation, has been increasing in manufacturing sites. AMR systems utilize map information and sensor data within the manufacturing environment to estimate their position, enabling them to move freely without the need for additional infrastructure. One notable feature is their ability to navigate dynamically, avoiding obstacles in real time. In this study, we address the importance of detour decision-making in a hybrid AMR system, which is constrained by narrow passages within the manufacturing sites. To improve system performance, various heuristic detour policies proposed in this study are compared with the DP policy. Furthermore, the impact of detour availability on system performance is analyzed through simulations, demonstrating the possibility for efficient selection of bypassing spaces from a system design perspective.
