Inverse kinematics solution based on fuzzy logic for redundant manipulators
An inverse kinematics solution that utilizes the differential felationship between the joint space and Cartesian space of redmdant manipulators is proposed. Until now, this solution can' be obtained using the pseudo-inverse of the Jacobian matrix. However the computation of the pseudoinverse is complex so that it is not easy to be implemented on a digital computer for on-line motion planning of...
متن کاملReal time inverse kinematics for general 6R manipulators
The inverse kinematics of serial manipulators is a central problem in the automatic control of robot manipulators The main interest has been in inverse kinematics of a six revolute jointed manipulator with arbitrary geometry It has been recently shown that the joints of a general R manipulator can orient themselves in di erent con gurations at most for a given pose of the end e ector However th...
متن کاملInverse 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...
متن کاملSingularity-Robust Inverse Kinematics Using Lagrange Multiplier for Redundant Manipulators
In this paper, a singularity-robust inverse kinematics is newly suggested by using a Lagrange multiplier for redundant manipulator systems. Two tasks are considered with priority orders under the assumption that a primary task has no singularity. First, an inverse kinematics problem is formulated to be an optimization one subject to an equality constraint, in other words, to be a minimization p...
متن کاملTask-priority inverse kinematics for underactuated redundant manipulators
Task control for underactuated redundant articulated robotic systems is addressed in this paper. In failed ground robots, as well as in aerial or underwater vehicle-manipulator systems, the unactuated degrees of freedom generally affect the task space variables to be controlled, and thus must be properly taken into account in the formulation of the control law. Within a multiple task-priority p...
