A 2-DOF manipulator is modeled in PROE. In MATLAB, inverse kinematics is solved by geometric method. The desired trajectory, angular velocity and angular acceleration of each joint are obtained by the linear interpolation of parabola transition to complete the kinematics planning of the manipulator. The velocity of the end-point and the kinematics analysis are got by Newton-Euler method. In PROE, the expected trajectory of the end point is got by the simulation of the position planning. Kinematics simulation on the model is made in ADAMS. The simulation results are consistent with theoretical calculations to verify the correctness of the theory computing, which can provide an effective basis for the control of the manipulator.

This three-part paper presents an approach to the control of dynamic interaction between a manipulator and its environment. Part I presented the theoretical reasoning behind impedance control. In Part II the implementation of impedance control is considered. A feedback control algorithm for imposing a desired cartesian impedance on the end-point of a nonlinear manipulator is presented. This algorithm completely eliminates the need to solve the “inverse kinematics problem” in robot motion control. The modulation of end-point impedance without using feedback control is also considered, and it is shown that apparently “redundant” actuators and degrees of freedom such as exist in the primate musculoskeletal system may be used to modulate end-point impedance and may play an essential functional role in the control of dynamic interaction.

Simulation Results

The kinematics simulation and modeling of a mechanical elbow of 3 degrees of freedom, is introduced by highlighting the main features of the mechanism related to the design criteria. The mechanical elbow is used as a transhumeral prosthetic part, and it has been built as a parallel topology consisting of electric linear actuators and universal joints. The parallel mechanism has 4 legs. 3 are electric linear actuators, and the fourth leg provides mechanical support for the whole structure and holds a DC Motor that performs the action of gripping objects. Furthermore, this paper shows the inverse kinematics for the elbow by geometric methods, and the MatLab‐simulation results show the workspace of the movement and the ability of the mechanical elbow to replicate the movements of a biological one.

Large Work

Giant structure processes involve highly dangerous manual welding operations. aiming at the welding for giant structures, tankers and other large work pieces, a five degrees of freedom (DOF) gantry type automatic welding robot was developed which has our own property right. Forward/inverse kinematics for the mechanical structure is analyzed in which pose of the welding torch is defined as a free vector. Then kinematics equations were proposed for torch pose fitting. Finally, simulation results for robot kinematics analysis and torch pose fitting were also proposed with Matlab. The result not only proves the feasibility of torch pose fitting, but also provides a basis for further study on kinematic analysis, torch pose fitting and off-line programming about gantry type automatic welding robot.

The Mathematical Model

Robotic arm with six degrees of freedom can be successfully used to do a surgical task through a small incision called (RCM point) on the patient's body. Inverse Kinematics modeling and simulating of a 6 DOF surgical robot is developed in this paper. The mathematical model equations are built using geometric approach and the Denavit-Hartenberg convention. The 3D model of the robot is created by CATIA5 to simulate the motion of the robot in surgical environments. The inverse kinematics equations model is validated through the simulating model. Result confirms that the proposed robot mechanism is applicable for minimally invasive surgery applications.

Recently the parallel manipulator with less DOFs has attracted industry and academia, but the research on its dynamics is still an open problem. In this paper, the inverse dynamic of a spatial parallel manipulator with two translational degrees of freedom and one rotational degree of freedom is studied based on the Newton-Euler approach. The kinematics analysis is firstly performed in a closed form. The inverse dynamic equation of this manipulator is formulated by using the Lagrange multiplier approach and choosing the Cartesian position and orientation as the generalized coordinates. Finally a numerical example is given for the kinematic and dynamic simulation of this manipulator. The model will be useful to improve the design of the mechanical components and the control algorithm.
