轻量人形机器人平台，安全易用，支持真实环境长期部署
Fauna Sprout: A lightweight, approachable, developer-ready humanoid robot
- 轻量化设计+柔顺控制+软性外壳，保障人机共处安全
- 集成全身控制、抓取与虚拟现实遥控，统一软硬件栈
- 带表情头部，支持社交交互，适合开发者快速上手
近期在学习控制、大规模仿真和生成模型方面的进展加速了通用机器人控制器的发展，但该领域仍缺乏适用于人类环境中安全、富有表现力且可长期部署的平台。现有大部分类人机器人要么是封闭的工业系统，要么是难以部署和操作的学术原型，限制了机器人进步。我们提出 Sprout，一个面向开发者的人形机器人平台，强调安全性、表现力与开发友好性。Sprout 采用轻量化结构，具备柔顺控制、有限关节扭矩和软性外壳，支持在共享人类空间中的安全运行。平台整合全身控制、集成夹持器的操作能力，以及基于虚拟现实的遥操作系统，形成统一的软硬件架构。可表达的头部进一步支持社交互动——这是多数功能型人形机器人尚未探索的领域。通过降低物理与技术门槛，Sprout 扩展了高性能人形平台的可及性，为在真实人类环境中发展具身智能提供了实用基础。
原文摘要 · Abstract (English)
Recent advances in learned control, large-scale simulation, and generative models have accelerated progress toward general-purpose robotic controllers, yet the field still lacks platforms suitable for safe, expressive, long-term deployment in human environments. Most existing humanoids are either closed industrial systems or academic prototypes that are difficult to deploy and operate around people, limiting progress in robotics. We introduce Sprout, a developer platform designed to address these limitations through an emphasis on safety, expressivity, and developer accessibility. Sprout adopts a lightweight form factor with compliant control, limited joint torques, and soft exteriors to support safe operation in shared human spaces. The platform integrates whole-body control, manipulation with integrated grippers, and virtual-reality-based teleoperation within a unified hardware-software stack. An expressive head further enables social interaction -- a domain that remains underexplored on most utilitarian humanoids. By lowering physical and technical barriers to deployment, Sprout expands access to capable humanoid platforms and provides a practical basis for developing embodied intelligence in real human environments.
