Robot Gripper Movement Accuracy Estimation by Using UWB Radar

This article deals with a non-destructive sensing method for estimation of the robot gripper which performs the single repetitive motions. This method comprises use of an UltraWideband (UWB) Radar, that can perform remote surveillance of a given process. This solution can be applied in some particular cases when conventional methods (e.g., induction or ultrasonic sensors) are not able to detect or estimate anomalies in the long-term behavior of at the first glance device in the suitable conditions. We suppose the case of mechanical damages or situations, e.g., in the meaning of using some malicious practices- attacking software. In the context of accuracy estimation, we demonstrate remote sensing technique by using the UWB radars for control and tracking of the movements in the technological process included robot gripper as a major object of interest.
