چکیده
This paper presents a new approach to path planning for m h ~ d a n t manipulatorsThe Path Planning Problem is PO& as a finite time nonlinear control problem which can be solved by a Newton-Raphson type algorithm together with an exterior penalty function as well as incorporating both joint and task space constraints. The algorithm has shown promising results in planning joint path sequences to meet Cartesian goal planning and path following. In contrast to approaches, this algorithm is less prone to problems such as singularities and local minima. Applications to planar 3R and 4R arms, cooperating 3R arms and a spatial 9 DOF arm are included. resolution by solving the differential relationship between joint and task space motion. Given the forward kinematics of the manipulator

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...

متن کاملOn the Global Optimum Path Planning for Redundant Space Manipulators
AbsCrocr-Robotic manipulators wiU play a significant role in the maintenance and repair of space stations and satellites, and other f u m space missions. Robot path planning and control for the above applications should be optimum, since any inetedency in the planning may considerably risk the success of the space mission. This paper prrsents a global optimum path planning scheme for redundant ...
متن کاملPath Planning and Collision Avoidance for Redundant Manipulators in 3d
We have developed a planner for redundant manipulators that is fast, eeective and versatile, based on the idea of treating each link of a rigid-linked robot as if it were slightly exible and under the innuenceof a potentialeld. We justify the method by exploringsome simple examples, and brieey describe the extensions to the basic method that allow it to plan paths for manipulators with revolute...
متن کاملA Continuous Approach To Robot Motion Planning With Many Degrees Of Freedom
There is a need for highly redundant manipulators to work in complex, cluttered environments. We explore kinematics and path planning for highly redundant manipulators by means of a continuous manipulator model, which captures the macroscopic shape of highly redundant manipulators. A path for the continuous manipulator model can be found by nding a smooth path for its end-e ector under a maximu...
