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工程和Mech-Viz工程

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_S12_Viz_ForLoop样例程序的代码及相关解释说明。

MM_S2_Viz_Basic是逐个转存规划的路径点,本样例是通过循环转存规划的路径点(加粗部分的代码)。因此,下文不再重复解释与MM_S2_Viz_Basic样例相同部分的代码(详情请参考MM_S2_Viz_Basic样例说明)。

流程 代码及说明

通过循环转存规划路径

FOR i FROM 1 TO pose_num DO
    count:=i;
    MM_Get_JPS count,jps{count},label{count},toolid{count};
ENDFOR
  • 第1行:FOR表示以下为循环程序片段;i用于控制循环的次数(即i从1开始,每次循环后自增1,直到大于pose_num,结束循环);pose_num为MM_Get_VizData指令的第二个参数,该参数表示视觉系统返回的路径点个数。

  • 第2行:将i赋值给count,count表示当前路径点在规划路径中的编号。

  • 第3行:MM_Get_Jps指令表示将某个路径点的关节角、标签和末端工具编号分别转存到指定变量,因此整条指令表示将第count编号的路径点的关节角、标签和末端工具编号依次转存到jps{count}、label{count}和toolid{count}变量。

假设本样例规划的路径有3个路径点,则上述循环等同于MM_S2_Viz_Basic样例中如下三条指令。

MM_Get_JPS 1,jps{1},label{1},toolid{1};
MM_Get_JPS 2,jps{2},label{2},toolid{2};
MM_Get_JPS 3,jps{3},label{3},toolid{3};
