Liu Hong, academician of the Chinese Academy of Engineering, the first batch of storage experts and a member of the review committee of the China Science and Technology Think Tank, and a space robot expert. He is currently the vice president of Harbin Institute of Technology and the director of the State Key Laboratory of Robotics and Systems. Customized Non-standard cast iron fittings
Liu Hong has been engaged in the research on the basic theory and dexterous manipulation technology of space robots for a long time, and presided over the development of my country’s first space robot. The relevant results have been successfully applied to the experiment of the No. 7 satellite and the Tiangong No. 2 laboratory. 863″ research project, which has made outstanding contributions to national space security and in-orbit services.
China’s first humanoid dexterous hand
China’s robotics industry started late, but China’s robotic dexterous hand technology is at the forefront of the world. In 2016, the space robot dexterous hand designed and developed by Liu Hong realized the world’s first man-machine collaborative on-orbit maintenance technology test on “Tiangong-2”, including removing thermal insulation materials, screwing screws with power tools, and on-orbit remote operation. Colleagues call it “practitioners” who put maintenance robots on Tiangong-2. Customized Non-standard cast iron fittings
In the early 1990s, Liu Hong completed the research on dexterous hands and control systems with various tactile functions, and proposed the theory of macro-micro-manipulator system. In 2001, Liu Hong led a team to develop the first humanoid robot dexterous hand in China, which has various sensing functions such as torque, position, temperature, and fingertip force. This research fills a gap in China’s field of robotic dexterous hands.
China’s first human-like dexterous hand, similar in size to a human hand, has 4 fingers, each finger has 4 joints, a total of 12 degrees of freedom, 96 sensors, a total of more than 600 mechanical parts, and 1600 surface mount electronic components multiple. The dexterous hand can play simple music; the researchers wear data gloves, which can control the dexterous hand from a distance, such as remote control of the dexterous hand to pour water.

In 2006, Liu Hong’s team developed a miniature torque sensor for use in dexterous hands. The European Space Agency, Brown University in the United States, and many universities in China and Germany have all become users of the dexterous hand of the miniature torque sensor.
Let the robot repair the spacecraft
Regarding the necessity of developing space robots, Liu Hong said: “Cars can be maintained in 4S stores, and aircraft can be repaired on the ground. Who will repair the spacecraft if there is a problem?”
Space robots are special robots that perform tasks such as space station construction and operation support, satellite assembly and service, scientific experiments, and planetary exploration in space. The research on space robot technology in my country began in the 1990s. In 2014, my country’s first robotic arm working in orbit went to the sky. In recent years, Chinese Academy of Sciences, Harbin Institute of Technology, Beijing University of Posts and Telecommunications, Beijing Institute of Technology, Beihang University, and the Fifth Academy of Aeronautics and Astronautics have carried out a lot of research on space robots and achieved fruitful results.

At present, China’s new generation of space robots can be equipped with highly dexterous robotic arms, infused with the concept of bionics. Liu Hong said that the robotic arms equipped with China’s space robots have achieved multi-joint continuum and fine operation; from a single robotic arm to multiple robotic arms and humanoid robotic arms; from the previous astronauts “teleoperation” in the sky, evolution It becomes the “master-slave remote operation” on the ground, and then to the ground-to-surface remote sensing operation.
In 2016, the 13th International Symposium on Space Artificial Intelligence, Robotics and Automation was held in Beijing. Liu Honghui said that although my country’s research in the field of space robotic arms is later than that of Europe and the United States and other regions and countries, my country’s development is very fast. As far as space robotic arms are concerned, my country’s level is currently at the forefront of the world.
Scientific research is a pleasure and a responsibility
In the mid-1980s, my country’s first Huayu-type I arc welding robot was successfully developed. The chief designer was Liu Hong’s teacher Cai Hegao. Liu Hong said that this was a great thing, so he applied for Cai Hegao’s graduate student. Research robots. Liu Hong said that to engage in scientific research, we should lay a solid theoretical foundation, practice basic skills, and then further cultivate innovation capabilities. Discover the law from the sorted facts, and thus invent and create something new. Customized Non-standard cast iron fittings
As the academic leader of the first batch of innovative teams of the Ministry of Education “Robots and Mechatronics Technology”, the team led by Liu Hong not only created a harmonious, democratic, united and cohesive small environment, but also created a good academic development for young people. surroundings. Liu Hong told the students, “Scientific research is a pleasure and a responsibility, and it is necessary to endure loneliness in doing research.” Customized Non-standard cast iron fittings
