This paper addresses the multiple tasks performing issues for redundant nonholonomic mobile manipulators. An extended gradient projection redundancy resolution scheme is proposed which can determine the directions of self-motion to perform multiple secondary tasks. This scheme is easy to use and can avoid algorithm singularities. A general dynamic modeling method is presented in consideration of nonholonomic...
This paper addresses the task-space trajectory following issue for a nonholonomic mobile modular manipulator, which is composed of a 4-degree-of-freedom (DOF) modular manipulator and a 3-wheeled nonholonomic mobile platform. An adaptive neural-fuzzy controller (ANFC) is presented to control the end-effector to follow a desired spatial trajectory in a 3-D space. The proposed algorithm does not need...
A robust adaptive neural-fuzzy (NF) controller is presented in this paper for trajectory following of nonholonomic mobile modular manipulators in task space. On the basis of modular robot concept, an integrated dynamic modeling method is proposed in consideration of the interactive motions and the nonholonomic constraints. NF systems are used as estimators to approximate dynamic model of the robot...
