Inverse Kinematics The state of the art

GMDH Type Neural Networks and Their Application to the Identification of the Inverse Kinematics Equations of Robotic Manipulators (RESEARCH NOTE)

An LPV Approach to Sensor Fault Diagnosis of Robotic Arm

One of the major challenges in robotic arms is to diagnosis sensor fault. To address this challenge, this paper presents an LPV approach. Initially, the dynamics of a two-link manipulator is modelled with a polytopic linear parameter varying structure and then by using a descriptor system approach and a robust design of a suitable unknown input observer by means of pole placement method along w...

Inverse Kinematics Resolution of Redundant Cooperative Manipulators Using Optimal Control Theory

The optimal path planning of cooperative manipulators is studied in the present research. Optimal Control Theory is employed to calculate the optimal path of each joint choosing an appropriate index of the system to be minimized and taking the kinematics equations as the constraints. The formulation has been derived using Pontryagin Minimum Principle and results in a Two Point Boundary Value Pr...

Solution of Inverse Kinematic Problem of a 2DOF Robot Using Decomposition Method

The inverse kinematics problem of a two degree of freedom (2DOF) planar robot arms issolved using Adomian’s decomposition method (ADM), after converting to a system of twononlinear algebraic equations. The advantage of the method is that it gives the solutions asfunctions of the desired position of the end effecter and the length of the arms. The accuracyof the solutions can be increased up to ...

Prioritized motion-force control of constrained fully-actuated robots: "Task Space Inverse Dynamics"

We present a new framework for prioritized multi-task motion/force control of fully-actuated robots. This work is established on a careful review and comparison of the state of the art. Some control frameworks are not optimal, that is they do not find the optimal solution for the secondary tasks. Other frameworks are optimal, but they tackle the control problem at kinematic level, hence they ne...
