During the synchronization maneuver, the robotic arm remains in the stowed configuration. 2015), comprises an approach along the major axis of rotation, starting from an inspection point at some 50 m distance, and with continuous and iterative synchronization of the relative motion and attitude. In addition, relative positioning and synchronization of the two spacecraft can only be done within the accuracy of the GNC (uncertainty box). Figure 2, Top depicts the chaser in a synchronized flight with the spinning target, at the arm delivery point, where it is aligned with the target’s center of mass and its maximal principal axis of inertia, at a distance of approximately 4m. The previous rendezvous maneuver of the chaser, described in detail in Wieser et al. The guidance, navigation and control (GNC) subsystem of the chaser, which holds the chaser synchronized to the target, is fed with the platform-mounted LIDAR sensor measurements, being used for relative pose estimation.

. However, due to potential future orbital collisions or internal incidents, such as uncontrolled valve venting, the current study considers up to 5 deg/s around any axis. These include analyses of the robot manipulator kinematics, the robot link flexibility dynamics, as well as the robot joint internal loads during some of the critical mission phases. The momenta transfer is performed via contact forces applied by the chaser’s gripper (or by joint forces and torques to transfer momenta within the chaser’s multibody system).

Through the impact, the linear and angular velocity of the target obviously decay. The Shuttle Remote Manipulator System (SRMS) was also used for satellite repair operations (Hubble). Apart from a controlled capture and de-orbiting, as planned within the e.deorbit scenario, the described robotic concept can also be used for on-orbit servicing (OOS) tasks, i.e., extending the lifespan of operational satellites through refueling or by repairing and replacing specific elements of a non-operational satellite. The MBS also features a Special Purpose Dexterous Manipulator (SPDM) (Mukherji et al., 2001) that recently conducted the Robotic Refueling Mission (RRM) demonstrating remotely controlled robotic servicing, including refueling with a dedicated experimental platform aboard the ISS (Cepollina and Reed, 2017). These systems can also be teleoperated by the crew and are being used for extravehicular activity (EVA) support, space station assembly and vehicle docking.

The resulting robot arm trajectory, which guarantees feasibility with respect to motion constraints, such as singularity avoidance and end-effector camera field-of-view requirements, is stored on board the chaser for online execution. Hooker’s approach is based on the addition of the independent equations of motion for each of the bodies to cancel the reaction forces, and the cancellation of reaction torques through a clever manipulation of the equations of motion. The target was defined to be ENVISAT, an eight-ton formerly Earth-observing satellite, that is defective and tumbling uncontrolled with a constantly declining spin rate of currently about 3 deg/s. The tumbling motion of the target was defined by ESA to be up to 5deg/s about any axis. Simulations consider an initial motion of Envisat of 5deg/s and multiple starting positions and orientations within and outside the GNC error box of 10 cm and 0.5deg relative positioning accuracy. Subsequently, results of kinematic and dynamic simulations are presented, aiming to prove the feasibility of the mission with the proposed technology and methods.

This paper is structured as follows: After a short description of the state of the art of related orbital robotic systems, the robotic operational strategy for performing the e.deorbit mission is described. The authors would like to thank all the supporting staff of the University of Strahclyde and DFKI GmbH along with other partners of the SIROM Project: SENER Ingenieria y Sistemas S.A. This includes the robotic joints, gripper and clamping mechanism. This provides a very solid, stiff, well-exposed, and well-defined structure, which is required for sufficiently designing a capable gripper that is able to achieve a stable form and force closure with it.
