示教4点实现码垛(无需创建user坐标系)

应用需求

仅需示教一层垛型的四个角点(无需创建user坐标系),按照示教的方向进行码垛和拆垛(不必先x后y方向)

导入test_pallet.jbi及test_pallet_setting.jbi程序,

导入pallet_calculation.lua,并加载到lua的第一个脚本

以下为码垛设置部分

150-159用于码垛

//P150--------------------->P152

// | 第二个方向 |

// | |

// | 第一个方向 |

// | |

//P151 -------------------- P153

P150 起点

P151第一个方向的末端点

P152 第二个方向的末端点

P153 远端参考点

I150 第一个方向码垛个数 (若该方向个数为1 ,设置为1)

I151 第二个方向码垛个数 (若该方向个数为1 ,设置为1)

I152 Z方向层数I153 单层层高,单位mm

仅码垛,打开test_pallet_setting.jbi,完成以上码垛数据的设置

使用时,打开机器人的V150-V153及V158 V159,P150-153变量

使用时,仅需导入test_pallet_setting.jbi和test_pallet.jbi,导入pallet_calculation.lua并加载到第一个lua脚本!!
