基于模型和无模型强化学习的机器人Kendama游戏

Robot Playing Kendama with Model-Based and Model-Free Reinforcement Learning

Shidi Li

摘要:

已经提出了几种基于模型和无模型的方法用于机器人轨迹学习任务。这两种方法各有优缺点。它们通常可以相互补充。许多研究工作试图将基于模型和非模型的方法集成到一个算法中,并在模拟器或准静态机器人任务中表现良好。当算法用于特定的轨迹学习任务时,仍然存在困难。在本文中,我们提出了一个机器人轨迹学习框架,精确的任务,不连续的动态和高速。从人的演示学习的轨迹进行优化DDP和PoWER先后。该框架在Kendama操作任务上进行了测试,这对人类来说也很难实现。结果表明,我们的方法可以规划的轨迹,成功地完成任务。

英文摘要:

Several model-based and model-free methods have been proposed for the robot trajectory learning task. Both approaches have their benefits and drawbacks. They can usually complement each other. Many research works are trying to integrate some model-based and model-free methods into one algorithm and perform well in simulators or quasi-static robot tasks. Difficulties still exist when algorithms are used in particular trajectory learning tasks. In this paper, we propose a robot trajectory learning framework for precise tasks with discontinuous dynamics and high speed. The trajectories learned from the human demonstration are optimized by DDP and PoWER successively. The framework is tested on the Kendama manipulation task, which can also be difficult for humans to achieve. The results show that our approach can plan the trajectories to successfully complete the task.
