Modeling and Control of Manipulator Dynamics using Modified Self-Organizing Maps
نویسندگان
چکیده
A dynamic modeling of a robot manipulator by means of a neural architecture is presented. Such model is applicable to generate a decoupling and linearizing feedback in the control loop of the robot drives. A modified extended Self-Organizing Map is used to perform the needed mapping of the robot’s movement state to the according joint torques. To get improved control performance by this, both correctness and smoothness of the approximated values are essential. This paper describes a suitable architecture for this, the so called Parametrized Self-Organizing Maps. A training of this neural network type by the Widrow-Hoff-learning-rule is introduced and different training methods are discussed.

Collision Avoidance for a Visuo - motor System Using Multiple Self - organizing Maps
Collision avoidance for a visuo-motor system in unstructured and cluttered environment is described. The achievement of collision avoidance is based on a simplified path planning system and motion control performed by self-organizing maps. The self-organizing maps are learned to determine joint angles of a redundant manipulator. Since the learning algorithm promises to make the manipulator reac...
متن کاملDynamic Modeling and Construction of a New Two-Wheeled Mobile Manipulator: Self-balancing and Climbing
Designing the self-balancing two-wheeled mobile robots and reducing undesired vibrations are of great importance. For this purpose, the majority of researches are focused on application of relatively complex control approaches without improving the robot structure. Therefore, in this paper we introduce a new two-wheeled mobile robot which, despite its relative simple structure, fulfills the req...
متن کاملDynamics of Space Free-Flying Robots with Flexible Appendages
A Space Free-Flying Robot (SFFR) includes an actuated base equipped with one or more manipulators to perform on-orbit missions. Distinct from fixed-based manipulators, the spacecraft (base) of a SFFR responds to dynamic reaction forces due to manipulator motions. In order to control such a system, it is essential to consider the dynamic coupling between the manipulators and the base. Explicit d...
متن کاملModifying a Conventional Grasping Control Approach for Undesired Slippage Control in Cooperating Manipulator Systems
There have been many researches on object grasping in cooperating systems assuming no object slippage and stable grasp and the control system is designed to keep the contact force inside the friction cone to prevent the slippage. However undesired slippage can occur due to environmental conditions and many other reasons. In this research, dynamic analysis and control synthesis of a cooperating ...
