Szukana fraza: [Abstract = "Properties \(a\) and \(c\) are of special interest in robotics problems, in which many of the variables are parameters that are measured \(i.e., known only up to some bounded errors\) while the modeling of the robot is based on parameters that are submitted to uncertainties \(e.g., because of manufacturing tolerances\). Taking into account these uncertainties is essential for many robotics applications such as medical or space robotics for which safety is a crucial issue."]
