We consider the kinematics of a mobile manipulator that consists of a non-holonomic (or holonomic) mobile platform and a holonomic manipulator mounted atop of the platform. At any fixed time instant and with fixed initial state of the platform these kinematics are viewed as a map from a Hilbert space of controls and manipulator’s joint positions into a taskspace of the mobile manipulator, and c...

With intensive research on robot and wide application of machine vision and movement control in relevant field of robot, image recognition and movement control of robot have become the research focus gradually. This thesis sets the plane non-holonomic mobile robot as the research subject, mainly discusses the control of the plane nonholonomic mobile robot based on image recognition, it has put ...

In this paper, the problem of coordinated motion control of a nonholonomic mobile platform with a serial manipulator mounted on top of the platform is addressed. The redundancy resolution algorithm bases on a constraint optimization approach, where the non–holonomic behaviour of the platform is modeled into inequality constraints leading to a convex optimization problem.

Mobile robots that consist of a mobile platform with one or many manipulators mounted on it are of great interest in a number of applications. Combination of platform and manipulator causes robot operates in extended work space. The analysis of these systems includes kinematics redundancy that makes more complicated problem. However, it gives more feasibility to robotic systems because of the e...

In this paper, a new methodology for motion control of mobile manipulator is presented. Motion control of mobile manipulator addresses the problem of trajectory tracking in autonomous mode witch allowing the endeffector and the plat-form to follow simultaneously desired trajectories without violating the non-holonomic constraints. Moving mobile manipulator systems presents many problems that ar...

Non-holonomic systems may appear in several forms, including combinations between holonomic and nonholonomic constraints for vehicle formations. Examples of the latter are non-holonomic formation constraints with holonomic vehicles or holonomic formation constraints with non-holonomic vehicles. In this paper the problem of non-holonomic systems with holonomic or non-holonomic constraints is add...

Designing a robot manipulator with fewer actuators than the dimension of its configuration space —to reduce bulk, weight and cost— becomes feasible by introducing mechanical elements that lead to non-holonomic constraints. Unfortunately, the mechanical advantages of these non-holonomic designs are usually darkened by the complexity of their control. This paper deals with motion planning for par...

{ This paper presents a sensor based docking strategy for a non holonomic mobile platform used to support material transportation operations in industrial like environments. A low cost in-frared sensor system was designed and implemented, aiming at locating the mobile platform relative to the docking station where passive reeectors are installed. With this information, trajectories are generate...

In the paper we present new control algorithms for a special class of mobile manipulators, namely for nonholonomic mobile manipulators. A mobile manipulator is defined as a robotic system composed of a mobile platform and a manipulator mounted on the platform equipped with non-deformable wheels. Such a combined system is able to perform manipulation tasks in a much larger workspace than a fixed...

An autonomous control system designed for a non-holonomic wheeled mobile robot that is programmed to emulate a fixed-wing unmanned air vehicle (UAV) flying at constant altitude is experimentally validated. The overall system is capable of waypoint navigation, threat avoidance, real-time trajectory generation and trajectory tracking. Both the wheeled mobile robot experimental platform and the hi...
