中文(ZH) 灵巧手的三大路线之争:连杆、腱绳与直驱 — Chestnut

Chestnut Robotics pursues hybrid dexterity for robot hands, blending tendon and AI

Chestnut Robotics is developing a dexterous robotic hand, opting for a hybrid architecture that primarily utilizes a tendon-driven system for fine manipulation. This approach aims to mimic human hand dexterity while incorporating AI for control. The company's founder, Evan Tao, a former key member of Tesla Optimus's dexterous hand team, highlighted the ongoing debate in robotic hand design between linkage, tendon, and direct-drive mechanisms. Chestnut's choice prioritizes the precision of tendon systems, addressing challenges associated with cost and control complexity in other designs. AI

影响 This hybrid robotic hand design, incorporating AI control, could advance the capabilities of humanoid robots in complex manipulation tasks.

    The Three Major Route Disputes of Dexterous Hands: Linkage, Tendon-String, and Direct Drive — Chestnut

    当下,有关灵巧手设计的核心迷思是:要不要像人手?围绕这一命题,诞生了连杆、腱绳、直驱三种设计方案。 其中,“连杆”最不像人手,但胜在成本低、易于控制;“腱绳”最像人手,可以做精细化操作,但成本高、控制难。“直驱”则是一种折中方案,将驱动单元直接集成在每个关节上,但成本不低,同时力传导效率和热管理上仍然面临工程层面的挑战。 混合架构路线,则是近期兴起的灵巧手技术解决方案。 Chestnut Robotics创始人、前Tesla Optimus灵巧手核心成员Evan Tao介绍,当下团队已经选择了混合架构路线,以可以完成精细化操作的腱绳结构为主,辅以AI控制
