- 在复杂姿态下完成液体转移等灵巧操作,精度高且重复性好
- 适合需要高精度操作的实验室自动化场景
许多现代机器人系统虽能自主运行,但往往缺乏环境分析与动态适应能力,而远程操控则需特殊操作技能。在实验室自动化领域,自动化流程日益增多,但多数系统仅针对特定任务设计。此外,该领域大量使用透明物体,使视觉分析变得困难。本文提出一种自主机器人框架,可对具有不同透明度的液体填充容器进行复杂姿态下的灵巧操作。实验验证了所设计视觉感知系统的鲁棒性,能准确估计物体6D姿态,支持如液体分装等高精度操作。该框架适用于实验室自动化,解决了在透明度和液位变化条件下实现高精度、可重复操作的任务挑战。
原文摘要 · Abstract (English)
Many modern robotic systems operate autonomously, however they often lack the ability to accurately analyze the environment and adapt to changing external conditions, while teleoperation systems often require special operator skills. In the field of laboratory automation, the number of automated processes is growing, however such systems are usually developed to perform specific tasks. In addition, many of the objects used in this field are transparent, making it difficult to analyze them using visual channels. The contributions of this work include the development of a robotic framework with autonomous mode for manipulating liquid-filled objects with different degrees of transparency in complex pose combinations. The conducted experiments demonstrated the robustness of the designed visual perception system to accurately estimate object poses for autonomous manipulation, and confirmed the performance of the algorithms in dexterous operations such as liquid dispensing. The proposed robotic framework can be applied for laboratory automation, since it allows solving the problem of performing non-trivial manipulation tasks with the analysis of object poses of varying degrees of transparency and liquid levels, requiring high accuracy and repeatability.
