Measuring system using a robot

A robot measuring system which automatically measures mechanical characteristics of an object to be measured when a bending load is applied to the object, the system comprising:

• a pressing robot for adding a predetermined pressing force to the object to be measured;
• force detection means, mounted to one end of a pressing rod, for detecting strength of the pressing force through the pressing rod;
• displacement detecting means for detecting a displacement of the object before and after the pressing force is applied thereto;
• a supporting robot for supporting the displacement detection means, and for moving the displacement detection means to a measuring position;
• a microprocessor for inputting resultant data of detection by the force detection means, for controlling a motion of the pressing robot based on the resultant data of detection, and for calculating various mechanical characteristics based on the detected resultant data input from the displacement detection means;
• and
• a memory for storing the various mechanical characteristics calculated by the microprocessor,
• wherein a calculation of the mechanical characteristics of a plastic molded article is performed by using a spline smoothing method on the resultant data.
