Reveal!Harbin Institute of Technology jointly developed the "big ability" of "small robotic arm"

At 0:33 on September 2nd, Shenzhou 14 astronauts' outlets were successful. In this task, a small robotic arm jointly developed by Harbin Institute of Technology and the Chinese Academy of Sciences accurately and stable to the operating point to accurately and stability to the operating point. The exercise was flexible and accurate. The process is smooth and complete, laying a solid foundation for the subsequent series of off -line operations.

Small robotic arm launch status of space station

Combined robotic arm

As one of the "star" components of the space station, what are the advantages of small robotic arm compared to large robotic arm? According to the responsible comrades of the relevant scientific research team of Harbin Institute of Technology, asking the small robotic arm of the Tianjie Experimental Class is about 5 meters long and the maximum load is 3 tons. Compared with the large robotic arm equipped with the core compartment, the small robotic arm is more delicate. The configuration, each end has an end -end, combined with the "footprint" on the surface of the experimental compartment, which can achieve crawling at different positions of the cabin. At the same time, I asked the Tiantian experimental cabin small robotic arm end positioning accuracy higher, the position accuracy is 5 times higher than the large robotic arm, and the attitude accuracy is doubled than the large robotic arm. Compared with the large robotic arm, it can be used to complete the higher accuracy requirements higher requirements. Scientific load installation, disassembly and other tasks.

In addition, small robotic arm can be used alone, and a combination of robotic arm with large robotic arm can be formed, and a large -scale, cross -cabin -supporting space officer out of the cabin, off -compartment status inspection, out -of -the -cabin's goods transfer and installation, off -class maintenance, off -cabin maintenance Mission, load care, optical facilities maintenance and other tasks. Harbin Institute of Technology related scientific research teams responsible comrades said that in the future, the small robotic arm will also complete the first space "handshake" with the large robotic arm. The length can reach 15 meters after the docking of both arms. The diversified task lays the foundation.
