The concept of space capture refers to the capability of a spacecraft to grasp a target satellite with the ultimate goal of executing servicing operations on the captured vehicle. Much research effort is currently focused on the development of technologies that enable such complex operations by means of autonomous vehicles.  1, record 1, English, - space%20capture

The application of free-flying space robots (FFSR) has achieved significant progress because of their ability to perform on-orbit servicing missions autonomously or telerobotically instead of human performing hazardous, monotonous and costly extra vehicular activities (EVA). Some applications of FFSR include inspection, repairing, assembling, refueling and docking with other spacecraft. As these tasks are dangerous for astronauts to perform in the space environment, space robots are expected to be utilized and therefore, a high level of accuracy is required for a successful mission.  2, record 2, English, - free%2Dflying%20space%20robot

For a spatial robot, there are two possible cases. A section may have two DOF [degrees of freedom] (most common) where the two degrees are derived from the bending motion of the robot. The set will contain two variables for each section, one to describe the bend and the other to describe the orientation of the bend in space. If we use curvature to describe the bending of the section, then we only need to use an angle about the initial tangent of a section to describe the orientation.  1, record 3, English, - spatial%20robot

The motion of free-floating space robots is characterized by non-holonomic constraints, i.e., non-integrable rate constraint equations. These constraints originate from the principles of conservation of angular momentum. It is well known that these rate constraints can also be written to form an input-affine drift-less control system. Trajectory planning of these systems is extremely challenging and computation intensive since the motion must satisfy differential constraints. Under certain conditions, these drift-less control systems can be shown to be differentially flat.  1, record 4, English, - free%2Dfloating%20space%20robot

To date, most of the research on the control of space robots has centered on "free-floating" robots. Free-floating robots are defined as space robots where the satellite base position and orientation are unactuated. Without base actuation, no external forces or torques act upon the system when the end-effector is not in contact with the work environment. The linear and angular momenta of the system are conserved, so the spacecraft base moves in reaction to commanded arm motion.  2, record 4, English, - free%2Dfloating%20space%20robot

Some papers selected single-arm space robots as actuators to touch and capture the target spacecraft in space. The in-orbit screw-driving manipulation by a single-arm space robot ... can cause the rotation and translation of the target spacecraft. Since the target is a free-floating spacecraft that is not a fixed object on the ground, the target will have reactive translational motion and rotation when external forces and torques are applied to the target spacecraft during the screwdriving process. However, the translation and rotation of the target spacecraft can influence the control accuracy of the space robot, which may lead to failures during the screw-driving process. Unlike single-arm space robots, dual-arm space robots can use the cooperation of the two arms to accomplish more complicated space tasks effectively. Therefore, dual-arm space robots can be introduced to carry out the in-orbit screw-driving operation by the mission arm and maintain the position and attitude of the target spacecraft by the other arm.  1, record 6, English, - single%2Darm%20space%20robot

Since its inception in 1958, NASA has accomplished many great scientific and technological feats in air and space. NASA technology also has been adapted for many non-aerospace uses by the private sector. NASA remains a leading force in scientific research and in stimulating public interest in aerospace exploration, as well as science and technology in general. Perhaps more importantly, our exploration of space has taught us to view the Earth, ourselves, and the universe in a new way.  3, record 7, English, - National%20Aeronautics%20and%20Space%20Administration
