چکیده

Future large space structures (LSS) will be constructed on orbit by assembling large subassemblies using teams of robots. Here, the challenging task of the control and planning of the cooperative manipulation of large flexible structural modules by such teams is addressed. The robots are mounted on the compliant LSS while moving a module to its pre-assembly position. The objective is to position the module accurately and to minimize the induced vibration in the large structure and the module. A method is developed to control the forces applied by the robots to the module and their support structures, which exploits robot cooperation and redundancy. The method is evaluated using simulations.

Manipulation of Flexible Structural Modules by Space Robots During LSS Construction

Future space structures are expected to have very large size. Such Large Space Structures (LSS) will be constructed in-orbit, probably by assembling large structural modules. This is a dangerous and difficult task for humans. On the other hand, this is a challenging and promising application for space robotics. This work provides a planning and control architecture for the manipulation of a lar...

Manipulation Control of a Flexible Space Free Flying Robot Using Fuzzy Tuning Approach

Cooperative object manipulation control of rigid-flexible multi-body systems in space is studied in this paper. During such tasks, flexible members like solar panels may get vibrated that in turn may lead to some oscillatory disturbing forces on other subsystems, and consequently produces error in the motion of the end-effectors of the cooperative manipulating arms. Therefore, to design and dev...

Control of Wheeled Mobile Manipulators with Flexible Suspension Considering Wheels Slip Effects

Wheeled mobile manipulators utilize both the locomotion capabilities of the wheeled platform and manipulation capacity of the arm. While the modelling and control of such systems have previously been studied, most of them have considered robots with rigid suspension and their wheels are subject to pure rolling conditions. To relax the aforementioned limiting assumptions, this research addresses...

Dynamics of Space Free-Flying Robots with Flexible Appendages

A Space Free-Flying Robot (SFFR) includes an actuated base equipped with one or more manipulators to perform on-orbit missions. Distinct from fixed-based manipulators, the spacecraft (base) of a SFFR responds to dynamic reaction forces due to manipulator motions. In order to control such a system, it is essential to consider the dynamic coupling between the manipulators and the base. Explicit d...
