将肌肉型人形与缆绳驱动机器人结合,实现超常规动作。

CubiXMusashi: Fusion of Wire-Driven CubiX and Musculoskeletal Humanoid Musashi toward Unlimited Performance

  • 通过缆绳连接环境并缠绕驱动,融合两种人形优势。
  • 实现引体向上、从躺姿起身等高难度动作。
  • 为非肌肉型人形提供新能力拓展思路,适合机器人设计者参考。

人形机器人在关节结构、驱动方式和自由度方面差异显著,导致其可实现的动作和任务各不相同。特别是肌肉型人形机器人旨在高度模拟人体结构与运动功能,由骨骼框架和大量肌肉驱动器构成,其肌肉数量相对于骨骼自由度存在冗余,从而能表现出人类复杂的柔性运动。然而,由于身体柔性和高自由度,建模、仿真与控制极为困难,限制了可行动作范围。本研究将肌肉型人形机器人Musashi与缆绳驱动机器人CubiX相结合,形成新型混合系统CubiXMusashi。该系统通过缆绳与环境连接并利用缠绕驱动,成功实现了引体向上、从躺姿起身及空中踢腿等复杂动作,突破了Musashi自身能力边界。这一构想表明,各类人形机器人(不仅限于肌肉型)可通过连接外部环境并借助缆绳驱动,克服物理局限,获得新能力。

原文摘要 · Abstract (English)

Humanoids exhibit a wide variety in terms of joint configuration, actuators, and degrees of freedom, resulting in different achievable movements and tasks for each type. Particularly, musculoskeletal humanoids are developed to closely emulate human body structure and movement functions, consisting of a skeletal framework driven by numerous muscle actuators. The redundant arrangement of muscles relative to the skeletal degrees of freedom has been used to represent the flexible and complex body movements observed in humans. However, due to this flexible body and high degrees of freedom, modeling, simulation, and control become extremely challenging, limiting the feasible movements and tasks. In this study, we integrate the musculoskeletal humanoid Musashi with the wire-driven robot CubiX, capable of connecting to the environment, to form CubiXMusashi. This combination addresses the shortcomings of traditional musculoskeletal humanoids and enables movements beyond the capabilities of other humanoids. CubiXMusashi connects to the environment with wires and drives by winding them, successfully achieving movements such as pull-up, rising from a lying pose, and mid-air kicking, which are difficult for Musashi alone. This concept demonstrates that various humanoids, not limited to musculoskeletal humanoids, can mitigate their physical constraints and acquire new abilities by connecting to the environment and driving through wires.
