Abstract:

Hyper-redundant manipulators having degrees of freedom much more than required, have many

advantages and important capabilities. In this paper, modeling of the manipulator dynamics is done

using a special curve called 'backbone' curve, modal method, Lagrangian mechanics and geometric

transformation between variables space of backbone curve and manipulator joints. The dependency of

the nonlinear and coupled terms of the dynamics model to joint variables makes some difficulties in

classical methods to controller design. To overcome this problem, fuzzy controllers that have

appropriate efficiency in complex and nonlinear systems are used. For demonstrating this matter,

dynamics modeling of 10 degrees of freedom manipulator is done. Then a fuzzy controller is designed

with attention to the dynamics behavior of the system. Manipulator behavior through various and

noisy inputs are evaluated by simulation of the model including fuzzy controller. The results show

very small error in manipulator motions and suitable condition of the designed fuzzy controller

based on the dynamics model.
