摘要: 针对机器人装配过程难以建立精确的物理模型,导致机器人装配灵活性差、装配成功率低的问题,提出一种基于过程建模的机器人分阶引导装配方法,建立基于装配各阶段的力、力矩、位姿装配过程模型,结合装配状态与机器人执行动作之间的映射,形成机器人装配阶段引导策略。通过在所搭建的KUKA机器人装配平台上进行算法验证表明,装配阶段的识别准确率达到99%以上,分阶引导策略下机器人的装配成功率达到97.2%。

Abstract: The accurate physical model is difficult to build in robot assembly,which leads to poor flexibility and low success rate of assembly.To solve this problem,a robot phased guided assembly method based on process modeling was proposed.An assembly process model based on force,torque,position and posture in each stage of the assembly was established.By combining with the mapping relationship between each stage in the assembly process and the robot's execution actions,a phased guiding strategy of robot assembly was formed.Through the built KUKA robot assembly platform,the algorithm verification showed that the recognition accuracy rate of each assembly stage reached more than 99%,and the assembly success rate under the phased guidance strategy reached 97.2%.

Key words: robot, assembly modeling, contact state, stage guidance
