By a News Reporter-Staff News Editor at Robotics & Machine Learning Daily News Daily News-Research findings on robotics are disc ussed in a new report. According to news originating from Stuttgart, Germany, by NewsRx correspondents, research stated, "Concentric tube robots (CTR) have gain ed popularity in robotic research due to their potential for smAller instrument sizes, enhanced dexterity and reduced trauma. However, CTR control can be comple x, with tip direction and curvature being kinematicAlly coupled." The news correspondents obtained a quote from the research from University of St uttgart: "To address this, a symmetric eccentric tube robot (ETR) is presented, where three identical pre-curved wires are arranged in parAllel and constrained by an outer sheath. Instrument curvature is controlled by a single input angle. This study aims to demonstrate the suitability as manuAlly actuated instrument. A model for curvature as a function of input angle is presented, and a prototype ETR with an outer diameter of 1 mm is assembled and evaluated. The results show that the ETR follows the expected shape, the curvature decreasing with the sepa ration angle in an almost linear way that may be perceived as intuitive and pred ictable by the human user. However, some unsteady behavior (snapping) is observe d, which may be addressed by preventing torsion of the wires through mechanical means."
