## 核心内容

针对屋顶施工高风险与重复性痛点，研究者搭建专用屋顶测试台架，对商用四足机器人 `Unitree Go2` 进行基准性能评估。这是业界首次系统量化四足机器人在倾斜屋面环境的运动能力边界，揭示了通用平台直接部署于建筑高空作业场景时的关键物理限制与安全阈值。

实验数据显示，标准球足在斜面上的滑移量随倾角增加呈二次方增长，仅在极小坡度下能完成起卧动作；当坡度达25°时已出现规律性运动失效。研究指出解决该问题需结合任务导向的足端设计、高级接触力学建模及基于强化学习的屋顶自适应步态控制策略，而非仅依赖通用运动算法。

## 关键看点

- **滑移特性**：标准球足在斜面滑移量随倾角呈二次方增长，25°坡面即发生规律性运动失效
- **起卧限制**：受限于足端摩擦与支撑几何，机器人仅能在小倾角条件下安全完成起身与趴下序列
- **技术路径**：突破屋顶作业瓶颈需融合专用足端硬件、接触力学模型及RL自适应步态策略

## 工程与产业观察

该研究为具身智能在建筑施工领域的落地提供了关键负样本数据。它警示开发者：通用四足本体在非结构化高空场景存在物理极限，单纯依靠端到端算法难以弥补机械接口缺陷。未来行业需转向“场景定义硬件”范式，通过可更换足端与专用RL策略构建垂直领域解决方案。

## 英文摘要 (Abstract)

This paper investigates the feasibility of deploying quadruped walking robots for the automation of work in roof environments. While quadrupeds have demonstrated versatility across various domains, their large-scale deployment remains limited, partly due to lack of application-specific designs. Roof environments represent a novel and unexplored use case, combining high safety risks for human workers with repetitive, strenuous tasks that could benefit from robotic assistance. A dedicated test rig of a roof's surface was designed to evaluate the baseline performance of a commercial quadruped, the \emph{Unitree Go2}, in this new environment. Experiments revealed that standard ball feet are inherently inadequate for locomotion on sloped roofs: slippage increased quadratically with incline angle, get-up and lie-down sequences were only possible on small inclines, and critical failures already occurred regularly on moderate inclines of 25°. This work provides the first systematic assessment of quadruped locomotion in roof environments, highlighting both the potential and the current limitations of this application and establishes a baseline for future research. Effective solutions will require a combination of task-oriented foot designs, advanced contact mechanics and environment-specific control strategies, such as reinforcement learning for roof-adapted gaits.
