چکیده

This paper analyses the reasons for resulting in the instability of mobile manipulator. Several methods of stability analysis and errors compensation are introduced, including the theories, the modeling processes and their characteristics. The significance of analysing the stability and compensating the errors are expounded. In addition, the corresponding applications are also discussed. Finally, the future study direction of mobile manipulator stability analysis and compensation is prospected. Key-Words: Mobile manipulator, stability, compensation, dynamics model, simulation

Coordinated Motion Planning for a Mobile Manipulator considering Stability and Manipulation

For a mobile manipulator to be used in areas such as offices and houses, it is desirable that the mobile platform be small sized. In the case of a small-sized platform, the mobile manipulator may tip over when moving at high speed or executing tasks in the presence of disturbances. Therefore, it is necessary to simultaneously consider both stabilization and manipulation while coordinating vehic...

Maximum load-carrying capacity of autonomous mobile manipulator in an environment with obstacle considering tip over stability

In order to increase the efficiency of wheeled mobile manipulators (WMM), it is preferred to carry the maximum payload, but in the case of a small-sized platform, which is desirable in applications, it may cause dangerous tip over, especially in the presence of obstacles. So, it is necessary to consider stability constraint in the determination of robot motion planning. This paper presents a no...

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...

Real-Time ZMP Compensation Method using Null Motion for Mobile Manipulators

In this article, the dynamic stability of a mobile manipulator using ZMP compensation is considered. A unified approach for the two subsystem is formulated using redundant scheme. First, to conserve the dynamic stability of the system, we define the performance index for the redundant system using ZMP(Zero Moment Point). This performance index represents the stability of the whole mobile manipu...

Motion Control and Stability Improvement of Autonomous Mobile Robots with Suspended Wheels

Mobile manipulators have been given extensive attention in recent years since they have many applications such as materials transport and service for disabled persons. A mobile modular manipulator is normally composed of an m-wheeled mobile platform and an n-degree-of-freedom (DOF) onboard modular manipulator. This combination extends the workspace of the entire robot dramatically. Building up ...
