Reports Outline Robotics Study Findings from Massachusetts Institute of Technology

May 26, 2014

By a News Reporter-Staff News Editor at Robotics & Machine Learning -- Data detailed on Robotics have been presented. According to news originating from Cambridge, Massachusetts, by VerticalNews correspondents, research stated, "In robotic single-port surgery, it is desirable for a manipulator to exhibit the property of variable stiffness. Small-port incisions may require both high flexibility of the manipulator for safety purposes, as well as high structural stiffness for operational precision and high payload capability."

Our news journalists obtained a quote from the research from the Massachusetts Institute of Technology, "This paper presents a new hyperredundant tubular manipulator with a variable neutral-line mechanisms and adjustable stiffness. A unique asymmetric arrangement of the tendons and the links realizes both articulation of the manipulator and continuous stiffness modulation. This asymmetric motion of the manipulator is compensated by a novel actuation mechanism without affecting its structural stiffness. The paper describes the basic mechanics of the variable neutral-line manipulator, and its stiffness characteristics."

According to the news editors, the research concluded: "Simulation and experimental results verify the performance of the proposed mechanism."
