Learning to Cooperate in Decentralized Multi robot Exploration of Dynamic Environments
This paper presents an approach to train a decentralized multi robot system to learn cooperation strategy in the exploration of dynamic environments. The traditional approaches to multi robot exploration problem are all based on the "pre designed" cooperation strategy. However, many real world settings are too complex for humans to "design" effective strategies. Besides, "pre designed" strategy does not possess the ability to adapt to different task environment features, which also limits its application in real world practices. Inspired by the superiority of deep reinforcement learning technique on complex individual behavior design, we apply the same technology to the cooperative learning process on the robot collective level. Our approach has been evaluated in a simulated multi robot Disaster Exploration scenario and the results show that it could be applied in more complicated scenarios in contrast with two traditional "human designed" methods.
