Mobile manipulation robots are envisioned to provide many useful services both in domestic environments as well as in the industrial context. In this paper, we present novel approaches to allow mobile maniplation systems to autonomously adapt to new or changing situations. The approaches developed in this paper cover the following four topics: (1) learning the robot’s kinematic structure and pr...

This paper presents a modeling method for a Mobile Modular Robot(MMR) which is composed of a mobile platform and a modular manipulator, the kinematics analysis is made for both the mobile platform and the upper manipulator. Then the dynamic equations are formulated considering the nonholonomic constraints and the controller is proposed with both the redundancy resolution and optimization of nul...

This paper presents a path planning technique for a mobile manipulator whose end-effector path is imposed by a given task. The planning is done decoupling the kinematics of the mobile platform and the manipulator, and planning for the former as a normal mobile robot. Two criteria for planning the path were implemented, one minimizing the need to turn the mobile robot and the other minimizing th...

This paper describes the application of behaviour-based control for a mobile manipulation task. It presents a preliminary result in the research into a ‘task-robust’ controller for a service robot, needed when a robot is used in a human-centred environment. The chosen benchmark task is the co-operative carrying of a long object by a mobile manipulator and a human. The human will guide the task,...

In this article we present a proposal for a control architecture suitable for mobile manipulation. The approach attempts to combine existing techniques for navigation and mobility with a flexible control system for the manipulator arm, hence a behavior-based system for controlling the platform is integrated with a hybrid dynamic system for the manipulator control. An analysis is made of the sys...

Nowadays the size and dimension of mobile manipulators have been decreased for being usable in various regions. This leads several problems such as danger of instability. Therefore, many researches have been done to overcome the problem of overturning of a mobile manipulator. In this paper, an algorithm for increasing the stability of a mobile manipulator is presented based on the optimization ...

This paper presents a computational technique for determining the maximum allowable load of wheeled mobile manipulators for a desired trajectory. Full load motion of mobile manipulators while carrying a load is an important consideration in their application and motion planning. The number of factors limits the maximum allowable loads, which can be achieved by a mobile manipulator during a give...

This project presents investigations into the applications and performance of embedded input shaper in command shaping techniques for vibration control of a flexible manipulator. A constrained planar single-link flexible manipulator is considered and the dynamic model of the system is derived using the assume mode method. An unshaped bang-bang torque input is used to determine the characteristi...
