Admittance-Based Motion Planning with Vision-Guided Initialization for Robotic Manipulators in Self-Driving Laboratories
- 将阻抗控制器嵌入轨迹执行,实时响应外力与人为干预。
- 通过平面特征检测与深度融合,精准定位纹理物体并生成初始轨迹。
- 适合需要人机协作的自动化实验室,提升安全性与灵活性。
自动驾驶实验室(SDL)是高度自动化的研究环境,依赖先进技术在极少人工干预下完成实验与数据分析。这类环境常涉及精密设备、不可预测的交互以及偶发的人类介入,因此柔顺且力感知的控制对保障安全、适应性和可靠性至关重要。本文提出一种以阻抗控制为核心的运动规划框架,实现机器人操作的自适应与柔顺性。与传统方法不同,该方案将阻抗控制器直接集成于轨迹执行阶段,使机械臂在交互过程中可动态响应外部力。这一能力支持操作员实时干预或重定向机器人动作。基于结构化平面姿态估计的视觉算法通过特征提取、单应性估计和深度融合,实现对纹理平面物体的检测与定位,为运动规划提供初始目标配置。视觉初始化生成参考轨迹,而嵌入式阻抗控制器确保轨迹执行过程始终安全、自适应,并能响应外部力或人为干预。所提策略以纹理图像检测为例进行验证。未来工作将拓展至透明实验物体场景,进一步增强自主性、安全性和人机协作能力。
原文摘要 · Abstract (English)
Self driving laboratories (SDLs) are highly automated research environments that leverage advanced technologies to conduct experiments and analyze data with minimal human involvement. These environments often involve delicate laboratory equipment, unpredictable environmental interactions, and occasional human intervention, making compliant and force aware control essential for ensuring safety, adaptability, and reliability. This paper introduces a motion-planning framework centered on admittance control to enable adaptive and compliant robotic manipulation. Unlike conventional schemes, the proposed approach integrates an admittance controller directly into trajectory execution, allowing the manipulator to dynamically respond to external forces during interaction. This capability enables human operators to override or redirect the robot's motion in real time. A vision algorithm based on structured planar pose estimation is employed to detect and localize textured planar objects through feature extraction, homography estimation, and depth fusion, thereby providing an initial target configuration for motion planning. The vision based initialization establishes the reference trajectory, while the embedded admittance controller ensures that trajectory execution remains safe, adaptive, and responsive to external forces or human intervention. The proposed strategy is validated using textured image detection as a proof of concept. Future work will extend the framework to SDL environments involving transparent laboratory objects where compliant motion planning can further enhance autonomy, safety, and human-robot collaboration.
