“…The dynamics of a deployable truss structure unit, which can be employed to construct large space systems [34], was investigated in this section. As shown in Figure 7, the structure unit is an assembly composed of three square frames, eight cross-bars, and eight diagonal rods joined to one another.…”

With increasing of the size of spatial truss structures, the beam component will be subjected to the overall motion with large deformation. Based on the local frame approach and the geometrically exact beam theory, a beam finite element, which can effectively reduce the rotational nonlinearity and is appropriate for finite motion and deformation issues, is developed. Dynamic equations are derived in the Lie group framework. To obtain the symmetric Jacobian matrix of internal forces, the linearization operation is conducted based on the previously converged configuration. The iteration matrix corresponding to the rotational parameters, including the Jacobian matrix of inertial and internal forces in the initial configuration, can be maintained in the simulation, which drastically improves the computational efficiency. Based on the Lagrangian multiplier method, the constraint equation and its Jacobian matrix of sliding joint are derived. Furthermore, the isogeometric analysis (IGA) based on the non-uniform rational B-splines (NURBS) basis functions, is adopted to interpolate the displacement and rotation fields separately. Finally, three dynamic numerical examples including a deployment dynamic analysis of spatial truss structure are conducted to verify the availability and the applicability of the proposed formulation.

With the increase of on-orbit maintenance and support requirements, the application of a space manipulator is becoming more promising. In actual operation, the strong coupling of the free-floating space robot itself and the unknown disturbance of the contact target caused a major challenge to the robot base posture control. Traditional Reaction Null Space (RNS) motion planning and control methods require the construction of precise dynamic models, which is impossible in reality. In order to solve this problem, this paper proposes a new Adaptive Reaction Null Space (ARNS) path planning and control strategy for the contact of free-floating space robots with unknown targets. The ARNS path planning strategy is constructed by the Variable Forgetting Factor Recursive Least Squares (VFF–RLS) algorithm. At the same time, a robust adaptive control strategy based on the Strategy Self-Adaption Differential Evolution–Extreme Learning Machine (SSADE–ELM) algorithm is proposed to track the dynamic changes of the planned path. The algorithm enables us to intelligently learn and compensate for the unknown disturbance. Then, this paper constructs a robust controller to compensate model uncertainty. A striking feature of the proposed strategy is that it does not require an accurate system model or any information about unknown attributes. This design can dynamically implement RNS path tracking performance. Finally, through simulation and experiment, the proposed algorithm is compared with the existing methods to prove its effectiveness and superiority.

“…This refueling approach is in line with the European industry (OHB, Thales Alenia Space) and is expected to merge with European commercial operators as the first step towards becoming an international standard [36]. Specifically, the definition of an on-orbit robotic refueling mission can be extended to the scope of manned space flight, providing fuel and other essentials for spacecraft [10]. On-orbit refueling includes the following parts: the capture mechanism, a standard docking interface for mechanical connections, a standard interface for fuel connections, a propellant refueling and transfer process, and replenishment of other consumables.…”

Development of a Novel End-Effector for an On-Orbit Robotic Refueling Mission

et al. 2020

At present, the space station on-orbit service is still rapidly developing, and on-orbit refueling operation has not been fully realized. During the process of an on-orbit robotic refueling mission, the pipe disconnectors are artificially docked, and the problems of low efficiency and a long operation period are common. From the perspective of bionics, this paper studies the kinematics of the upper limbs in the manual docking process of the pipeline quick disconnector and analyses the redundant degrees of freedom in the manual docking process. In this paper, without changing the original structure of the quick disconnector, a five-degrees-of-freedom multifunctional end-effector imitating the human hand with a compact structure and a light weight was created, which can realize the automatic docking of the quick disconnector in the pipeline. The quick disconnector docking in the refueling system is simplified from the original manual, twohanded operation to a single-end-effector operation with a single mechanical arm. Compared with a dual-arm robot, a single-arm robot has the advantages of internal force sealing, a stable structure, a higher docking accuracy and a lower cost. The common rigid body contact collision dynamics problem is thus studied. The contact dynamics model between the ''quick disconnector and the robot end-effector'' is established by the equivalent spring damping model method. The experimental prototype was developed according to the structure of the end-effector to complete the construction of the refueling robot experimental platform. A simulation and experiment were conducted to verify the advantages and effectiveness of the structure. INDEX TERMS On-orbit servicing, robotic refueling mission, end-effector, imitating human hand, collision dynamics analysis.
