On Grasping a Tumbling Debris Object with a Free-Flying Robot
نویسنده
چکیده
The grasping and stabilization of a tumbling, non-cooperative target satellite by means of a free-flying robot is a challenging control problem, which has been addressed in increasing degree of complexity since 20 years. A novel method for computing robot trajectories for grasping a tumbling target is presented. The problem is solved as a motion planning problem with nonlinear optimization. The resulting solution includes a first maneuver of the Servicer satellite which carries the robot arm, taking account of typical satellite control inputs. An analysis of the characteristics of the motion of a grasping point on a tumbling body is used to motivate this grasping method, which is argued to be useful for grasping targets of larger size.

Active Orbital Debris Removal Using Space Robotics
One of the main technical challenge in orbital debris removal (ODR) missions is how to capture a tumbling and drifting space object given several environmental and operational constraints. This paper focuses on the guidance of a robot manipulator in a preand postgrasp phases to capture and stabilize a drifting and tumbling space object with uncertain dynamics. A Kalman filter is used to estimat...
متن کاملManipulation 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...
متن کاملDynamics 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...
متن کاملAerial Grasping: Modeling and Control of a Flying Hand
In this paper, we present the design, simulation and experimental validation of a control architecture for a flying hand, i.e., a system made of an unmanned aerial vehicle, a robotic manipulator and a gripper, which is grasping an object fixed on a vertical wall. The goal of this work is to show that the overall control allows the flying hand to approach the wall, to dock on the object by means...
متن کاملAn Energy Balance Based Method for Parameter Identification of a Free-Flying Robot Grasping An Unknown Object
The estimation of inertial parameters of a robotic system is crucial for better trajectory tracking performance, specially when model-based controllers are used for carrying out precise tasks. In this paper, we consider the scenario of grasping an object of unknown properties by a free-flyer space robot with limited actuation. The problem is to find the inertial parameters of the complete syste...
