Motion control of nonholonomic robots at low speed

Formation Compound Control for Nonholonomic Mobile Robots under Motion Constraints

The formation keeping characteristics for nonholonomic autonomous mobile robots are investigated in this paper. A novel approach of compound control is presented, which deals with the formation task based on two different algorithms: a flexible feedback linearization control algorithm and an optimal approximate target algorithm. And the algorithms are selected according to robot’s expected loca...

Planning spiral motion of nonholonomic space robots

A freeying space robot with a 6 DOF manipulator cannot follow an arbitrary trajectory in the 9D generalized coordinates(3 of the satellite orientation and 6 of the manipulator) with only manipulator joint control, though it was shown to be commonly controllable in the literature. In this paper, we propose a method to approximate the desired 9D path by introducing a perturbation around it. We ca...

On Motion Planning of Nonholonomic Mobile Robots

Mobile robots that consist of a mobile platform with one or many manipulators, are of great interest in a number of applications. This paper presents a methodology for generating paths and trajectories for both the mobile platform and the manipulator that will take a system from an initial configuration to a pre-specified final one, without violating the nonholonomic constraint. The generated p...

Nonholonomic motion planning for car-like robots

We consider the robot motion planning problem in the presence of non-integrable kinematic constraints, known as non-holonomic constraints. Car-like non-holonomic mobile robots are used for solving this problem, and several implemented planners are discussed. We claim that the randomized methods are more capable of efficiently solving many challenging, high-dimensional problems. Results with ran...
