By a News Reporter-Staff News Editor at Robotics & Machine Learning Daily News Daily News-Fresh data on Robotics are presented i n a new report. According to news reporting out of Brescia, Italy, by NewsRx edi tors, research stated, "This paper presents a low-cost pose measuring device cap able of simultaneously measuring All six coordinates (3 translations and 3 rotat ions) of a rigid body with respect to a given reference frame. The proposed syst em consists of a mechanical chain of rigid bodies and two encoders." Our news journalists obtained a quote from the research from the University of B rescia, "The mechanism is a spatial four-bar linkage system with a symmetrical R evolute-Spherical-SphericalRevolute (RSSR) kinematic structure, where two encode rs measure the rotation of the revolute joints. The mechanism is investigated th eoreticAlly and solved kinematicAlly using a numerical estimation method. The un certainty of the pose determination, caused by the repeatability of the sensors, is estimated, as well as the achievable measurement range. A low uncertainty is achieved by a suitable design of the proposed kinematic chain. The mechanism is easy to realize with low tolerances and the correct definition of the length of the links Allows a quite large workspace. The system can be profitably used in the calibration of robots or multi-axis machine tools where the actual pose of the gripper or spindle must be measured over the workspace of the machine."
