摘要:

四足机器人能否像人类一样执行双足运动?尽管类人行为的开发更多是在昂贵的双足机器人平台上研究,但我们提出了一种在轻量级四足机器人上的解决方案,在直立站立姿态下释放四足机器人的敏捷性,并能够完成多种类人运动。我们的框架采用分层结构。底层是一个运动条件控制策略,使四足机器人能够在依靠两只后脚保持平衡的同时,跟踪期望的基座和前肢运动。该策略由高层运动生成器指挥,后者根据多种模态的人类输入,向机器人提供参数化类人运动的轨迹。我们首次在四足机器人上展示了多种双足运动,并展示了有趣的人机交互模式,包括模仿人类视频、遵循自然语言指令以及物理交互。视频可在 https://sites.google.com/view/bipedal-motions-quadruped 获取。

英文摘要:

Can a quadrupedal robot perform bipedal motions like humans? Although developing human-like behaviors is more often studied on costly bipedal robot platforms, we present a solution over a lightweight quadrupedal robot that unlocks the agility of the quadruped in an upright standing pose and is capable of a variety of human-like motions. Our framework is with a hierarchical structure. At the low level is a motion-conditioned control policy that allows the quadrupedal robot to track desired base and front limb movements while balancing on two hind feet. The policy is commanded by a high-level motion generator that gives trajectories of parameterized human-like motions to the robot from multiple modalities of human input. We for the first time demonstrate various bipedal motions on a quadrupedal robot, and showcase interesting human-robot interaction modes including mimicking human videos, following natural language instructions, and physical interaction.
