流程 | 代码及说明 | ||
---|---|---|---|
获取工件组朝向 |
机器人通过MM_GET_PLNDT指令获取路径点的视觉移动规划数据,然后再通过MM_GET_PLJOP指令将路径点的视觉移动规划数据从机器人内存中转存至指定寄存器中。示例中,抓取点(PR[61])的视觉移动规划数据从R[100 ]开始存放。R[116]表示工件组与吸盘长边的朝向关系,0表示平行,1表示垂直。 上述代码表示,将R[116]赋值给R[10],则R[10]将表示工件组朝向。 |
||
根据工件组朝向采取不同的放置策略 |
上述代码表示,如果工件组与吸盘长边平行(即R[10]为0),则将该工件组放置在P[4]处;否则,将该工件组放置在P[6]处。 |
