Abstract

The invention discloses a deformable space motion arm. The deformable space motion arm comprises a fixed-length rod, a telescopic rod, a rod bionic joint, a gripper assembly, a base, a rotating shaft and a plurality of sliding locks. The telescopic rod is connected with the fixed-length rod through the rod bionic joint. The gripper assembly is connected with the telescopic rod through the rotating shaft in the base. The gripper assembly comprises a plurality of gripper petals, and each gripper petal comprises a plurality of knuckles which are connected through gripper bionic joints, wherein the gripper bionic joints can adjust the angle between the knuckles. The sliding locks are arranged on the gripper petals in a sleeving mode, can slide on the gripper petals and are used for sliding to the gripper bionic joints to be combined together and clasped to draw and lock the gripper petals. The motion arm is simple in structure, easy to control and operate, capable of conducting rotating and three-dimensional maneuvering and high in adaptability.

Description

technical field [0001] The invention belongs to the technical field of space manipulation, and more particularly relates to a deformable space manipulation arm. Background technique [0002] Aerospace technology is one of the high-tech technologies with the most development potential in the world today, and it is an important factor to measure a country's scientific and technological strength, determine a country's international status, and ensure national security. Since the beginning of the new century, the world's aerospace powers have launched fierce competition around aerospace technology, applications and industries. [0003] Space technology and applications mainly use spacecraft as the main carrier. Developed countries such as the United States and Germany have conducted in-depth research in this field. The United States launched the "Front End Robot Technology Recent Demonstration" (FREND) project; Germany launched a comprehensive satellite on-orbit operating syst...
