FLAM: Foundation Model-Based Body Stabilization for Humanoid Locomotion and Manipulation

arXiv.org Artificial Intelligence

Humanoid robots have attracted significant attention in recent years. Reinforcement Learning (RL) is one of the main ways to control the whole body of humanoid robots. RL enables agents to complete tasks by learning from environment interactions, guided by task rewards. However, existing RL methods rarely explicitly consider the impact of body stability on humanoid locomotion and manipulation. Achieving high performance in whole-body control remains a challenge for RL methods that rely solely on task rewards. In this paper, we propose a Foundation model-based method for humanoid Locomotion And Manipulation (FLAM for short). FLAM integrates a stabilizing reward function with a basic policy. The stabilizing reward function is designed to encourage the robot to learn stable postures, thereby accelerating the learning process and facilitating task completion. Specifically, the robot pose is first mapped to the 3D virtual human model. Then, the human pose is stabilized and reconstructed through a human motion reconstruction model. Finally, the pose before and after reconstruction is used to compute the stabilizing reward. By combining this stabilizing reward with the task reward, FLAM effectively guides policy learning. Experimental results on a humanoid robot benchmark demonstrate that FLAM outperforms state-of-the-art RL methods, highlighting its effectiveness in improving stability and overall performance.


Japan's Defense Ministry unveils first basic policy on use of AI

The Japan Times

The Defense Ministry unveiled its first basic policy on the use of artificial intelligence on Tuesday, as Japan looks to stave off a manpower shortage and keep pace with China and the United States on the technology's military applications. The focus on AI comes as the Self-Defense Forces grapple with concerns about recruitment and its abilities to harness the power of new technologies. "In our country, where the population is rapidly declining and aging, it is essential to utilize personnel more efficiently than ever before," Defense Minister Minoru Kihara told a news conference after the policy's release. "We believe that AI has the potential to be one of the technologies that can overcome these challenges."
