چکیده

This paper investigates how to track a desired trajectory by a mobile manipulator that has redundant degrees of freedom (DOFs). Our approach is based on the analysis of its position and orientation. In the first part of the analysis, the manipulator contributes sub-vectors projected on the Z axis in the world frame, including position and orientation. In the second part, the mobile base and the manipulator move along the direction of the desired path and reach the sub-vectors on axes X and Y in the world frame respectively. Simulated results are presented to show the effectiveness of our approach.

Dynamic 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...

Including a non-holonomic constraint in the FSP (full space parameterization) method for mobile manipulators' motion planning

The efficient utilization of the motion capabilities of mobile manipulators, Le., manipulators mounted on mobile platforms, requires the resolution of the kinematically redundant system formed by the addition of the degrees of freedom (d.0.f.) of the platform to those of the manipulator. At the velocity level, the linearized Jacobian equation for such a redundant system represents an underspeci...

Design and Motion Planning for a Zero-Reaction Manipulator

In a number of industrial, space, or mobile systems applications, reaction forces and moments transmitted by a manipulator to its base are undesirable. Based on force and moment transmission analysis, a three DOF redundant manipulator design is selected aiming at reactionless motions. Dynamic reaction forces are eliminated by using force balancing. Reaction moments are eliminated by following r...
