WebAug 1, 2024 · In this context, the identification method relies on "Circle Point Analysis". The points are measured with a laser tracker. Indeed, with a relevant processing of the measured points, we directly identify the invariants of joints. This method is applied to a SCARA robot geometric modeling. WebAbstract. The major approaches toward kinematic calibration are unified by considering an end-point measurement system as forming a joint and closing the kinematic loop. A …

WebMar 1, 2014 · Circle point analysis offers an interesting point of view of robot calibration, but it lacks accuracy. That is because circle point analysis only shows positioning errors of robot axes and, as seen in this paper, rotatory errors can be a higher source of errors than kinematic parameters.
