چکیده

The problem of planning a safe trajectory for a free-flying robot to approach an uncontrolled spinning satellite is addressed. First, a heuristic plan is presented for a simple planar case, which constructs a collision-free path within realistic system constraints. Second, a general numerical optimization technique for planning a safe spatial trajectory is presented. In it, the approach path is parameterized and a cost function based on performance metrics is minimized in order to find the optimal path. The results are analyzed, and it is shown that optimization techniques can be used to produce a far safer approach trajectory than the heuristic method.

Approach Planning and Guidance for Uncontrolled Rotating Satellite Capture Considering Collision Avoidance

The problem of planning safe kinematic approach trajectories for robotic capture of an uncontrolled rotating satellite is addressed, and two methods of trajectory planning are presented. The first method uses equations of orbital mechanics to plan a passive fly-by approach path for certain conditions of target satellite motion. The second method uses optimization techniques to plan an approach ...

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...

Planning and Control During Robotic Satellite Capture

Robotic technologies have played an important role on several space missions in the past, and they are likely to play an increasing role on space missions in the future. Robots are particularly well suited for work in the dangerous and demanding space environment, which is an inherently inhospitable place for humans. There are a number of mission scenarios that could rely heavily or exclusively...

Optimal motion planning for free-flying robots

This paper addresses the problem of motion planning for free-flying robots. Full state actuation is considered to allow for large displacements of the spacecraft. Motion planning is formulated as an optimization problem and kinematic as well as dynamic constraints are considered. The chosen optimization criteria are spacecraft actuation and final time. The proposed method allows solutions which...
