Researchers' Work from Thomas Jefferson University Focuses on Robotics (Analysis of a novel high-precision 5-degrees of freedom magnetic resonance imaging-compatible surgery robot for needle-insertion prostate brachytherapy)

By a News Reporter-Staff News Editor at Robotics & Machine Learning -- Research findings on Robotics are discussed in a new report. According to news reporting out of Philadelphia, Pennsylvania, by VerticalNews editors, research stated, "In this paper, we focus on the design requirement of a high-precision magnetic resonance imaging-compatible robot for prostate needle-insertion surgery, which is actuated by five ultrasonic motors to achieve the goal of needle posture adjustment and prostate puncture. After a brief introduction to the robot, the direct and inverse kinematic equations are deduced."

Our news journalists obtained a quote from the research from Thomas Jefferson University, "In order to show the relationship of the velocity between the actuators and the end effector, the Jacobian matrix is derived by formulating a velocity closed-loop equation for each limb. The kinematics is carried out by minimizing a global and comprehensive dimensional synthesis conditioning index subject to transmission angle and range of motion of the mechanism constraints."

According to the news editors, the research concluded: "The dimensional parameters are obtained for achieving a good kinematic performance throughout the entire task workspace by an example, and finally the reachable workspace of the robot is calculated."
