为了实现智能装配机器人能够模拟人装配机械零件,系统应包含有关装配所必需的知识.利用这些知识,机器人自动编制装配工艺规程.并自动安排机器人的一系列控制命令.机械零件知识库是基于知识的智能装配机器人规划系统中不可缺少的知识.本文介绍了由机器人的视觉系统摄入机械零件图纸后,如何由摄入的二值化图形自动建立机械零件知识库. In order to realize that intelligent assembly robots can simulate human assembly of machine parts, the system should contain the necessary knowledge about the assembly, so that the robot will automatically compile the assembly process and automatically arrange a series of robot control commands.The machine parts knowledge base is based on knowledge Which is an indispensable knowledge in the intelligent assembly robot planning system.This paper introduces how to automatically create the mechanical part knowledge base from the ingested binary image after the robot vision system takes in the mechanical part drawings.
