为进一步提升适用于草坪园艺管理的割草机器人整体作业效率,引入TRIZ发明问题解决理论针对其系统功能设计方法展开研究。根据割草机器人进行割草作业的运动学机理与系统实现功能构成,以TRIZ解决问题理论为基点,搭建割草作业核心解决问题模型,以降低其运行故障率。将TRIZ理论中的设计问题分析与冲突分析进行耦合,通过系统构件设计与功能实现后展开系统功能性试验,结果表明:在各功能模块协同运行良好的条件下,割草机器人的割草高度稳定性与割草覆盖率均可提高至90%以上,整机运行故障率较设计优化前改善了62.5%,整机割草作业效率较设计优化前可提高10.35%。该设计方法正确可行,能够为类似农业机器人的结构或系统功能优化提供一定的参考。

In order to further improve the overall work efficiency of mowing robot for lawn gardening management,the TRIZ invention problem-solving theory was introduced to study the system function design method.According to the kinematic mechanism of mowing robot and the functional composition of the system,and based on TRIZ problem-solving theory,the core problem-solving model of mowing operation was built,which was to reduce the failure rate.The design problem analysis and conflict analysis in TRIZ theory were coupled,then the system component design and function realization were done,and the system functional test was carried out.The results showed that under the condition that all functional modules work well together,the mowing height stability and mowing coverage of the mowing robot could be increased to more than 90%,and the operation failure rate of the whole machine was reduced by 62.5%,the mowing efficiency of the whole machine could also be increased by 10.35% compared with that before the design optimization,and the test effect was good.The functional design method was correct and feasible,which would provide some reference ideas for the structure or system function optimization of similar agricultural robots.
