Since 1985 when the first appear of robots in surgery field, the interest and the amount of research in surgical robots have been increase significantly. We study in this paper the kinematics of a 6dof surgical robot by determining Denavit-Hartenberg parameters using simple approach supported by robotic toolbox. We describe in details the forward kinematics using the D-H parameters, the successful build of the robot was verified by plotting 3D model for the robot in two positions.
Since robots began to inter the medical fields, more research efforts and more attention have been given to this kind of robots. In this paper six degrees of freedom surgical robot was studied. The Denavit-Hartenberg parameters of the robot have been computed and 3D model has been built by using open source robotics toolbox. The paper also discussed a closed form solution for the inverse kinematics problem by using inverse kinematic decoupling method.
Since 1985 when the first use of robot in surgery fields, the interest and the amount of research in surgical robots have been increase significantly. Various surgical robot systems have been developed, and many design models have been proposed. This paper discusses the development of surgical robot design and touches some design and control characteristics which are useful for the research in the field. The paper also provides the recent trends in the field and discusses some commercial surgical robots.
Forward Kinematic simulation of a 6 DOF surgical robot tracking a path through the constraint of the Remote Center of Motion point (RCM) is developed in this paper. Theoretical calculations of the forward kinematics are analyzed by solving the configuration kinematic equations of the robot. CAD prototype of the surgical robot and the patient are created using CATIA5 part and assembly tools. The theoretical results are validated through a Kinematic simulation of CATIA kinematics. The simulation results confirm the usefulness of the six revolute joint robots in minimally invasive surgery (MIS) and the efficiency of using the power full CATIA5 software to simulate surgical robot, and checking the robot mechanism capability of doing surgical procedures.
