It typically consists of a large amount of autonomous entities and interactions. To develop such system needs high-level metaphors and effective mechanisms independent of physical and technical details of various robots.The paper presents a multi-agent organization approach to developing autonomous robot software that is modelled as social organization, in which each agent is bound to specific roles with specified responsibilities that are tightly related with robot’s characteristics and tasks. These agents form diverse organization structure and patterns to achieve flexible cooperation in order to achieve assigned tasks. The paper details multi-agent organization model of autonomous robot software and various roles in the model. We have implemented a framework called AutoRobot that realizes the approach and supports the development and running of autonomous robot software. A case is studied by using NAO robot to show the effectiveness of our proposed approach.展开更多

The primary obj...This paper investigates the challenges associated with Unmanned Aerial Vehicle (UAV) collaborative search and target tracking in dynamic and unknown environments characterized by limited field of view. The primary objective is to explore the unknown environments to locate and track targets effectively. To address this problem, we propose a novel Multi-Agent Reinforcement Learning (MARL) method based on Graph Neural Network (GNN). Firstly, a method is introduced for encoding continuous-space multi-UAV problem data into spatial graphs which establish essential relationships among agents, obstacles, and targets. Secondly, a Graph AttenTion network (GAT) model is presented, which focuses exclusively on adjacent nodes, learns attention weights adaptively and allows agents to better process information in dynamic environments. Reward functions are specifically designed to tackle exploration challenges in environments with sparse rewards. By introducing a framework that integrates centralized training and distributed execution, the advancement of models is facilitated. Simulation results show that the proposed method outperforms the existing MARL method in search rate and tracking performance with less collisions. The experiments show that the proposed method can be extended to applications with a larger number of agents, which provides a potential solution to the challenging problem of multi-UAV autonomous tracking in dynamic unknown environments.展开更多
