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. Webformal observability analysis in order to identify degener ate paths of the calibration run. In contrast to the method presented in this paper, their approach still expects that t he robot travels along non-degenerate paths. A last class of methods relies on an energy function to be minimized. For instance, Levinson and Thrun [9] have
