程序简介

功能说明

机器人触发Mech-Vision工程运行以获取视觉结果,接着对标签进行解析,然后根据不同标签增加不同处理流程,进而执行抓取和放置操作。

文件路径

Mech-Vision和Mech-Viz软件安装目录下Communication Component/Robot_Interface/ABB/sample/MM_S17_Vis_ParseLabel

对于RobotWare6系统,文件后缀为.mod。对于RobotWare7系统,用户需将.mod修改为.modx

所需工程

Mech-Vision工程(输出步骤的labels端口需要存在数据)

使用前提

  1. 已完成标准接口通信配置。

  2. 已完成自动标定。

此样例程序仅是示例程序。用户需根据实际情况在此基础上进行修改,请勿直接使用该程序。

程序解读

以下为MM_S17_Vis_ParseLabel样例程序的代码及相关解释说明。

与MM_S1_Vis_Basic样例相比,本样例仅新增了解析标签的功能(加粗部分的代码)。因此,下文不再重复解释与MM_S1_Vis_Basic样例相同部分的代码(详情请参考MM_S1_Vis_Basic样例说明)。

上述样例程序代码对应的流程如下图所示。

下表为解析标签的逻辑解读。用户单击指令名称的超链接便可查看该指令的详细说明。

流程 代码及说明

将标签解析为label_1、label_2

!parse label info received from Mech-Vision, eg. "label=56" will decompose into 5 and 6
label_1:=label DIV 10;  !label_1=5
label_2:=label MOD 10;  !label_2=6

MM_Get_Pose指令可以将某个视觉点的工具位姿、标签和末端工具编号分别转存至pickpoint、label、toolid变量中。本样例假设label变量值为56,“label DIV 10”表示label整除10的商(即为5),“label MOD 10”表示label整除10的余数(即为6),如此便将label解析成label_1和label_2(即56解析成5和6)。

根据解析后的标签值添加处理逻辑

!add handling logic according to decomposed label value
IF label_1=5 THEN
    !add handling logic a
    Stop;
ELSE
    !add handling logic b
    Stop;
ENDIF

上述代码表示,如果label_1为5,则执行处理逻辑a;否则,执行处理逻辑b。用户可根据具体业务场景,针对不同的标签值,添加不同的处理逻辑。
