摘要:

仿人机器人在传感和感知方面存在显著差距,使其难以在密集环境中进行运动规划。为此,我们引入ARMOR,这是一种集成硬件和软件的新型第一视角感知系统,专为仿人机器人配备类似可穿戴的深度传感器。我们的分布式感知方法增强了机器人的空间感知能力,促进了更敏捷的运动规划。我们还在仿真中训练了一个基于Transformer的模仿学习(IL)策略来执行动态避碰,该策略利用了AMASS数据集中约86小时的人类真实运动数据。我们的实验表明,ARMOR感知系统优于配备多个密集头部安装和外部安装深度相机的设置,碰撞减少了63.7%,成功率提高了78.7%。我们还将IL策略与基于采样的运动规划专家cuRobo进行了比较,结果显示碰撞减少了31.6%,成功率提高了16.9%,计算延迟降低了26倍。最后,我们在傅里叶智能的真实GR1仿人机器人上部署了ARMOR感知系统。我们将在arXiv版本中更新源代码、硬件描述和3D CAD文件的链接。

英文摘要:

Humanoid robots have significant gaps in their sensing and perception, making it hard to perform motion planning in dense environments. To address this, we introduce ARMOR, a novel egocentric perception system that integrates both hardware and software, specifically incorporating wearable-like depth sensors for humanoid robots. Our distributed perception approach enhances the robot's spatial awareness, and facilitates more agile motion planning. We also train a transformer-based imitation learning (IL) policy in simulation to perform dynamic collision avoidance, by leveraging around 86 hours worth of human realistic motions from the AMASS dataset. We show that our ARMOR perception is superior against a setup with multiple dense head-mounted, and externally mounted depth cameras, with a 63.7% reduction in collisions, and 78.7% improvement on success rate. We also compare our IL policy against a sampling-based motion planning expert cuRobo, showing 31.6% less collisions, 16.9% higher success rate, and 26x reduction in computational latency. Lastly, we deploy our ARMOR perception on our real-world GR1 humanoid from Fourier Intelligence. We are going to update the link to the source code, HW description, and 3D CAD files in the arXiv version of this text.
