چکیده

Results are presented of an experimental study of a recently developed motion control algorithm for mobile manipulators. First, the dynamic interactions between a mobile manipulator and its vehicle are shown to lead to poor performance when a conventional fixed-base controller, which neglects these interactions, is used. Then the mobile manipulator control algorithm, which accounts for dynamic vehicle motions caused by manipulator motions, is shown to be stable and to perform well, while using only limited sensory data, such as would be practically available in highly unstructured field environments.

Maximum Allowable Dynamic Load of Flexible 2-Link Mobile Manipulators Using Finite Element Approach

In this paper a general formulation for finding the maximum allowable dynamic load (MADL) of flexible link mobile manipulators is presented. The main constraints used for the algorithm presented are the actuator torque capacity and the limited error bound for the end-effector during motion on the given trajectory. The precision constraint is taken into account with two boundary lines in plane w...

Large Motion Control of an Experimental Mobile Manipulator with Limited Sensing

ABSTRACT Two recently developed motion control algorithms for mobile manipulators are applied to an experimental system. The manipulator motions induce significant dynamic interactions with its vehicle and suspension. A conventional fixed-base controller, which typically neglects these dynamic interactions, is shown to lead to poor performance. Both mobile manipulator control algorithms, howeve...
