The invention provides a space chopstick tool for space target racemization capture and flexible control, and belongs to the technical field of space racemization mechanisms. The problem of space operation under the complex unknown state condition of the high-speed rolling non-cooperative target in the prior art is solved. A mechanical arm structure is connected with a base of a satellite base body, a chopstick mechanism is connected with the tail end of the mechanical arm structure, the chopstick mechanism is connected with the mechanical arm structure through a symmetrical fulcrum adjusting variable-rigidity joint in the pitching direction and the yawing direction, and the chopstick mechanism comprises a resistance rod section, a telescopic sleeve section and a brush section. The resistance rod section and the sleeve section are connected through a folding joint, the sleeve section and the brush section generate telescopic motion, the chopstick mechanism adjusts the length and configuration according to contact force to adapt to different non-cooperative target shapes, and the brush section is of a flexible structure, low in contact rigidity and used for eliminating seal and rotation. According to the invention, a chopstick-shaped mechanism with flexible hairs is used, so that the device has the characteristics of light weight, scalability, high controllability, flexible operation and the like.

    本发明提出了针对空间目标消旋捕获与灵巧操控的空间筷子工具,属于空间消旋机构技术领域。解决了现有技术中高速翻滚非合作目标复杂未知状态条件下的空间操作问题。其机械臂结构与卫星基体的基座连接,筷子机构与机械臂结构的末端连接,筷子机构通过有俯仰和偏航两个方向的对称式支点调节变刚度关节与机械臂结构连接,筷子机构包括阻力杆段、可伸缩套筒段和毛刷段,阻力杆段和套筒段之间通过折叠关节连接,套筒段和毛刷段之间产生伸缩运动,筷子机构根据接触力调整长度与构型以适应不同的非合作目标形状,毛刷段为柔性结构,接触刚度较低,用于消章消旋。本发明使用了附有柔性毛的筷子型机构,具备质量轻、可伸缩、高可控性、柔性操作等特点。
