In the first battle!The dexterous "small arm" jointly developed by Harbin Institute of Technology appeared in "Ask the sky"

Recently, the small robotic arm developed by Academician Liu Hong, Professor Xie Zongwu, and Professor Xie Zongwu of the School of Mechanical and Electrical at Harbin University of Technology, and the Chinese Academy of Sciences took the upward of the experimental compartment with the questioning compartment. It has achieved the expected effect, laying a solid foundation for the subsequent rails of the space robotic arm.

As one of the "stars" components of the space station, compared to the large robotic arm equipped with the core compartment, the small robotic arm is more delicate and uses 7 freedom symmetrical configuration. There is a terminal at both ends; its arm is nearly 6 meters in length of nearly 6 meters. , Effective operation space is about 5 meters, with a maximum load of 3 tons; it can be used alone, or a combined robotic arm can be formed with large robotic arm; Maintenance, load care, optical facilities maintenance, etc. 6 application tasks.

Researchers are detecting small robotic arms

Compared with big arm advantages

For the first time, the small robotic arm has been up upward with the cabin section and the function and performance confirmation. What are the test content? In this regard, the school's relevant personnel explained the science popularization.

1. Firework unlock

The small robotic arm is tested on the orbit. The first thing to do is to unlock the firework. After unlocking, the small robotic arm can be charged to start various tests. Aerospace firework device is a general term for device and device for one -time use of gunpowder, explosive explosives, or mechanical skills.

2. Product self -inspection

After the small robotic arm was unlocked, the small robotic arm was gradually unfolded in the orbit test. Researchers first inspect the various products of the robotic arm. The inspection content mainly includes the controller status confirmation, joint inspection, end inspection, etc.

3. Single joint expansion

Single joint development is tested on the joints of small robotic arms to confirm that the joints can be developed normally. Completing various fine operations and inspections in space requires that small robotic arms have sufficient coverage area. For this reason, the single joint energy on the small robotic arm needs to be detected normally. This is like a person's joints, arthroplahetic activities, and talents can walk smoothly.

4. Crazy action confirmation

After the joints are unfolding, the small robotic arm will be confirmed on the tower. This is an important foundation for the operation of the robotic arm to perform off -cabin operations. Robotic arm crawling seems easy, but it has many technical difficulties. The adapter that is connected during the climbing of robotic arm is exposed to the effect of space environment for a long time and will face the risk of aging and degeneration. To this end, scientific researchers will design an automatic closing device to protect the adapter of the robotic arm docking on the cabin, but at the same time, it also increases the difficulty of climbing of the robotic arm. Therefore, it is necessary to confirm that its closed device can run normally before the crawling task is performed.

5. Bet from the base

After the adapter on the side of the small robotic arm, another end of the small robotic arm needs to be separated from the base. This is the "first step" of the small robotic arm. Just like walking, you need to step by step. When the second end of the small robotic arm is separated from the base, the small robotic arm truly achieves the "walking" of the shot. Whether the small robotic arm can go from the foundation smoothly, determining its ability to carry out follow -up tasks.

6. Sunwing, cabin and mouth inspection and load target tab

During the crawling of small robotic arm, there will be 4 small robotic arm adapters on the top of the cabin. Each adapter is like the "footprint" of a small robotic arm. After passing all the "footprints" of the small robotic arm, you can ensure that each adapter can be ensured Points are tested and verified. In this process, the small robotic arm will perform the solar wings, the outlet and mouth inspections, and the load target target fixed work at the same time. After all confirmation is correct, the small robotic arm will return to the original position to form a long -term storage configuration.

7. Joint test

After the ground scientific researchers test and confirm the small robotic arms, the "three -party joint test" of astronauts, small robotic arm, and small robotic arm operation desks will be carried out. The spacecraft will operate the small robotic arm on the operation of the tablet. This is the first time the Shenzhou 14th multiplication group controls and operates a small robotic arm.

Combined robotic arm

In the future, scientific researchers will also launch a large robotic arm test. After the test is completed, the size robotic arm will provide support for subsequent tasks and other tasks. The two robotic arms configured by the space station will realize the practical function of 1+1> 2 to meet the needs of the space station task.
