BED FOR TESTING ACCURACY DEGREE OF CONTOUR MOVEMENTS OF INDUSTRIAL ROBOT Russian patent published in 2002 - IPC

FIELD: measuring technique, possibly testing parameters of contour movement of robots such as accuracy, recurrency, vibration. SUBSTANCE: bed includes technological foundation, pattern unit, three pickups for detecting linear motions, registration system connected with pickups and supporting strut. Registration system is in the form of personal computer provided with built-in analog-to-digital converter to be connected to said pickups. The last are mounted on supporting strut in such a way that sensitivity axis of each pickup is oriented along one axis of Cartesian coordinate system. Pattern unit has contact part in the form of ball mounted with possibility of engaging with linear movement pickups. EFFECT: improved accuracy at measuring error of real robot path relative to program set path. 1 dwg
