Abstract
Description
[溶接ロボットシステムの基本構成]
図2は、本発明の一実施形態に係るロボット教示システム200の機能的な構成を例示する図である。図2に示されるように、ロボット教示システム200は、機能的な構成として、例えば、撮影部211と、カメラ座標系設定部212と、動作経路設定部213と、プログラム生成部214とを有する。これらの機能のうち、撮影部211は、撮影端末1が有する機能である。他方、カメラ座標系設定部212、動作経路設定部213及びプログラム生成部214は、撮影端末1及びロボット制御装置2のどちらかが全てを備えてもよいし、撮影端末1及びロボット制御装置2に各機能を分散して備えてもよい。また、撮影端末1及びロボット制御装置2以外の他の装置が、上記機能の一部又は全部を備えてもよい。
次に、撮影端末1を用いて画像を撮影し、適切に溶接位置に溶接可能な作業プログラムを生成するまでの具体的な様子について、詳しく説明する。
次に、ロボット教示システム200がカメラで撮影した画像を用いて、適切に溶接位置に溶接可能な作業プログラムを生成するロボット教示方法について、具体的に詳しく説明する。
