Logistics robots face many challenges such as sensors

electromechanical products; artificial intelligence; Industrial automation; Robot market; Business opportunities of logistics robot industry; Data show that in 2018, China's express business volume reached 50.71 billion pieces. Driven by this huge market, logistics robots are rising rapidly. Amazon, Alibaba, jd.com, Shentong, SF, and other e-commerce giants and express delivery leaders have stepped up the layout of logistics robots, and smart logistics has become a general trend in the industry

however, Professor liuyunhui of the Chinese University of Hong Kong pointed out in an interview with every classic (hereinafter referred to as NBD): Although logistics robots have made rapid development, they still face challenges in terms of reliability, accuracy, flexibility and efficiency in the natural environment

liuyunhui is an expert in robotics and automation technology, mainly engaged in research work in the fields of robotics, automation technology and information science

logistics robots need to perceive, move and operate intelligently

nbd: with the progress of artificial intelligence and other technologies, the autonomous and intelligent development of robots has become a new trend and a difficulty in the integration of artificial intelligence. How intelligent is the robot under the current technical conditions

liuyunhui: there are still great differences in the understanding of robot intelligence between the public and the academic community. Many technologies can be demonstrated, but there are still many difficulties in real application. Robots are more complex than artificial intelligence. Artificial intelligence is mainly based on computer reasoning, language and image processing, but robots also involve behavioral intelligence, which changes the surrounding environment through behavior, so it also involves materials, control, structure and other issues. Taking human hands as an example, the current dexterous hands can not achieve the flexibility of human hands

nbd: your current key research fields include logistics robots. What is the current development status of logistics robots in China? In practice, what are the main factors restricting development

liuyunhui: relatively speaking, logistics robots have developed rapidly because of the large market demand. The logistics industry is labor-intensive and has the requirements of precision and speed, which can only be solved by robots. Based on the development of robot technology automation and unmanned logistics, the main work of logistics robots at present is handling and operation, including sorting, packaging, etc. Therefore, technically speaking, we need robots with perceptual intelligence, mobile intelligence and operational intelligence

as far as the logistics robot is concerned, its work is more complex because it does not work in a structured environment. The challenges include reliability, accuracy, efficiency and flexibility. In addition, cost is also an important consideration. The logistics industry is not very profitable, so a low-cost solution must be given

specifically, a problem to be solved at present is whether the sensor can work in all situations, whether indoors or outdoors, whether in strong sunlight or rainstorm. When perception is wrong, judgment and behavior control will be wrong. Therefore, it is necessary to ensure the reliability and accuracy of the sensor without interference, which is the main difficulty at present. Therefore, technological innovation and breakthrough must be made to solve the final problem

high end technology still needs to break through

nbd: in 2018, China's industrial robot production slowed down after years of high growth, and showed negative growth in the first quarter of this year. What may be the reason? How do you view the market space of industrial robots in China

liuyunhui: in the past few years, the robot industry developed rapidly under the promotion of policies. However, it should be understood that industrial robots can not solve all the problems and operations in the industrial field. The market has high expectations for robots, but some problems will not be solved after the introduction. In addition, in the past year, affected by the economic situation, the manufacturing pressure increased and the demand for robots decreased

however, automation is a trend in the long run. The labor cost of the manufacturing industry is increasing, and there is a shortage of young labor, so the replacement of machines has to be done. There is no doubt that these innovation teams usually carry out basic research and development abroad

nbd: what is the development level of carbon nanotubes with good heat transfer performance for robots in China? What are your suggestions for further development

liuyunhui: Chinese robots have made great achievements in key algorithms and application scenarios. However, high-end products and core components still depend on foreign countries, and high-end controllers and reducers are still monopolized by Japan, Germany, the United States, Switzerland and other countries

therefore, in order to become a robot power, it is essential to strengthen the breakthrough of key technologies and pay more attention to high-end equipment and technology. At present, the industry has great expectations for the constant speed control range of machine force: 0.05% ⑴ 00%fs people, and has invested a lot of money. The academic community should fully tap new technologies, strengthen technological innovation, break through basic technologies and key technologies, and solve the neck sticking problem when accurately evaluating the fatigue performance of materials. At present, the establishment of the sci-tech innovation board is also of great help to technological innovation and help robot innovation enterprises solve the capital problem
