    摘要:

    為提高遙操作機器人的安全性和操作性能,利用人類對力覺信息更敏感的特點和視覺特有的“預(yù)測與導(dǎo)引”功能,將視覺對現(xiàn)場環(huán)境的認知結(jié)果以虛擬力(包括作業(yè)對象引力,、障礙物斥力)的方式同操作者的操縱力信號融合,,提出遙操作機器人的力感示教控制策略。力感示教控制策略將機器智能與人類高級決策的優(yōu)點相結(jié)合,,可有效提高遙操作機器人的作業(yè)效率與局部自主,,降低對操作者熟練程度的要求,以及避免大時延系統(tǒng)中由圖像時滯導(dǎo)致的機器人操控盲目性,。對該控制系統(tǒng)的體系結(jié)構(gòu),、作業(yè)環(huán)境空間信息的提取、控制方法等進行了闡述,,并通過實驗驗證了控制方法在提高遙操作機器人作業(yè)效率和安全性等方面的優(yōu)越性,。

    Abstract:

    In order to improve the safety and manipulation performance for telerobotic system, a kinesthesis teaching control strategy for telerobotics was presented. Utilizing the characteristics of human’s sensitivity to force information as well as the specific feature of vision’s forecast and guidance, the control force of the operator with the virtual forces was merged, including the attraction force from objectives, and the rejection force from obstacles, which were generated from the recognition results of working fields based on vision techniques. Furthermore, it combined the advantages of machine intelligence with human’s high-level decision, which could improve effectively the working efficiency as well as local autonomy of tele-robot, and reduce the proficiency requirements of operator. Especially, in a teleoperation system with large time delay, the method could avoid the blinded manipulation of robot caused by lagging transmission of image. The system structure, extraction of the operating environment spatial information and control methods were introduced in detail. The superiority of the proposed control strategy in improving the operating efficiency and security of the telerobotic system were verified by relative experiments.
