摘要:

自从将深度Q学习应用于Atari类游戏中的连续动作域以来,用于运动控制的深度强化学习(Deep-RL)技术得到了质的提升。如今,现代Deep-RL可以成功应用于解决多种类型车辆的各种复杂决策任务。基于这一背景,在本文中,我们提出使用Deep-RL为混合无人机水下航行器(HUAUVs)执行自主无地图导航,这些机器人可以在空气或水介质中操作。我们开发了两种方法,一种是确定性的,另一种是随机的。我们的系统使用车辆的相对定位和简单的稀疏范围数据来训练网络。我们比较了我们的方法与传统的几何跟踪控制器的无地图导航。基于实验结果,我们可以得出结论,基于Deep-RL的方法可以成功地用于HUAUV的无地图导航和避障。我们的车辆完成了两种情况下的导航,能够通过这两种环境中实现所需的目标,甚至优于基于几何的跟踪控制器的避障能力。

英文摘要:

Since the application of Deep Q-Learning to the continuous action domain in Atari-like games, Deep Reinforcement Learning (Deep-RL) techniques for motion control have been qualitatively enhanced. Nowadays, modern Deep-RL can be successfully applied to solve a wide range of complex decision-making tasks for many types of vehicles. Based on this context, in this paper, we propose the use of Deep-RL to perform autonomous mapless navigation for Hybrid Unmanned Aerial Underwater Vehicles (HUAUVs), robots that can operate in both, air or water media. We developed two approaches, one deterministic and the other stochastic. Our system uses the relative localization of the vehicle and simple sparse range data to train the network. We compared our approaches with a traditional geometric tracking controller for mapless navigation. Based on experimental results, we can conclude that Deep-RL-based approaches can be successfully used to perform mapless navigation and obstacle avoidance for HUAUVs. Our vehicle accomplished the navigation in two scenarios, being capable to achieve the desired target through both environments, and even outperforming the geometric-based tracking controller on the obstacle-avoidance capability.
