Robots gather in Jinshitan to launch underwater "machine warfare"

Morning News (Peninsula Morning News, 39-degree video reporter Su Lin) The crab-pincer-like manipulator prowled among the sand and rocks on the seabed, suddenly reaching out to the scallop in front of the "face", opening the "pincers" to clamp it firmly and put the scallop in the cabin … In 2022, the national underwater robot contest (Dalian) was in full swing on the Golden Coast of Jinshitan, from universities, scientific research institutions and top industries all over the country.

OurEDA No.2 Team of Dalian University of Technology, which belongs to Dalian Key Laboratory of Underwater Robots, brought an agile robot with full digital structure to participate in the competition. Liu Yu ‘ang, a junior majoring in microelectronics at Dalian University of Technology, told reporters that this fourth-generation medium-sized agile robot participated in the autonomous grasping competition in this competition. It is an improved version of the eight-axis robot, and its action is more sensitive. "We have changed the internal control structure, equipped with a high-power edge calculation module, especially for image detection. It used to be an analog camera, but now it is an all-digital structure. The newly designed autonomous crawling algorithm can complete the operation of artificial intelligence. "

Liu Yu ‘ang introduced that, considering that natural factors such as ocean currents are often encountered in the sea, the team introduced the function of self-balance in the process of improving the robot, which can keep balance in front, back, left and right, up and down directions. "This robot can also have a better orientation and depth. For example, suspend at a distance of one or two meters from the seabed, observe the situation of the seabed, and grab the sea treasures within a certain range. " In addition, the fourth generation medium-sized agile robot has also designed a number of data interfaces, and external accessories such as sonar and USBL can be added as needed.

"The stone seams and reef walls on the real seabed are our’ main battlefield’." Lin Peng, the leader of Haiying No.1 Team from Dalian Maritime University, told the reporter that the underwater robot Haiying No.1 is a robot independently developed and designed by them to catch seafood such as scallops, sea cucumbers and sea urchins. This robot is waterproof to 200 meters, driven by 6 propellers, with high degree of freedom and flexible control. It has a 30-fold mechanical arm, and can be grasped at 160 angles around the fan. The relatively small "hand shape" is specially designed by the team for real seabed crevices. In the competition of man-machine cooperation, "Haiying No.1" caught 25 sea treasures per unit time.

According to reports, another feature of "Haiying No.1" is that it uses shore-based battery power supply. Robots don’t need their own batteries, and at the same time, they can realize 24-hour nonstop operation all day. Besides underwater fishing, this robot can also be used in underwater search and rescue, underwater reconnaissance, underwater scientific research and archaeology and other fields.

Yong Li Chaotou Team from Zhejiang University came to Dalian for the first time to participate in the National Underwater robot contest. This is also the first time that the underwater robot independently developed by this team has gone out of the laboratory pool to "test the water" in the real sea area. Huang Puwen, a member of the team and a senior majoring in marine engineering and technology in Zhejiang University, said that everyone cherishes this rare exercise opportunity. The robot in this competition is a multifunctional modular ROV designed and developed by the team for more than one year. It adopts an open frame structure with eight propellers, and its small size and high-efficiency propellers make it have strong flexibility and endurance. This robot can achieve a certain degree of suspension in water, and the diving design index can reach 10 meters. "It has been tested in the swimming pool of the school laboratory before. Although the effect of grabbing is OK, it can’t simulate the wind and waves in the real sea area after all. This is the first time I have come to the real sea area. After discovering the problem, we can improve it more pertinently. "

Urban governance rule of law: take the "Shanghai Domestic Waste Management Regulations" as an example

Since the reform and opening up, the urban management of Shanghai can be divided into three stages: the initial stage of reform and opening up to 2000, the construction management is cracked by solving the "three difficulties" (difficulty in transportation, housing difficulties, and environmental difficulties). With people -oriented, management as the first, safety as the first, to welcome the "Expo" event and consolidate "comprehensive management" as the main task; since 2017, it has entered refined management to make good use of the "three hearts and one needle" (embroidery -like " Carefulness, patience, excellence, and embroidery needle), build four beams and eight pillars.

After more than forty years of practice and exploration, Shanghai has accumulated rich experience in the process of dealing with various complex problems operating in large cities, and conducted a comprehensive exploration in the refinement of urban management.

In 2021, the Shanghai Housing and Urban -Rural Development Management Committee organized the writing "Exploration and Practice Series of the Construction of" People’s City "in the New Era". Strengthen the refined work of urban management and promote the exploration and practice of people’s urban construction. The book uses the four main "needle methods": rule of law, standardization, intelligence, and socialization (fourizations), combined with cases to detailed how Shanghai performs refined management.

In the chapter of the "rule of the rule of law" the "warning line" of urban management, the writing group cuts in from the legislative, revision, law enforcement and law popularization of the city management field in Shanghai, analyzes the application of the rule of law thinking in the management process, and confirms the construction of the rule of law. Fundamental role in urban management. We have edited some of the contents of this chapter, explained the necessity of rule of law in urban management, and selected one of the most representative cases in order to readers.

For a long time, Shanghai has always regarded the rule of law as an important cornerstone of the construction of governance systems and governance capabilities, based on the management needs of oversized cities, and continuously refining and optimizing the guarantee of legal systems.

In early 2021, driving into the Fenhu Daokou of the G50 Shanghai -Chongqing High Speed ??Speed ??and entering the boundary of Shanghai, Mr. Lin, who was sitting in the co -driver, received a text message- "The Regulations on the Administration of Shanghai Public Health Emergency" will be implemented on November 1, 2020. Everyone is responsible for preventing and controlling and controlling it according to law. Strengthen self -health management, strengthen self -protection awareness, wash hands, divide hands, use public chopstick spoons. Enter the airport, railway station, bus, subway and other public places to wear masks as required to maintain social distance ""

"It is illegal to wear a mask in Shanghai in public places." Mr. Lin turned his head and told his friends and took out the mask from his pocket.

The "Regulations on the Administration of Public Health Emergency" clearly stipulates that during the popularity of respiratory infectious diseases, entering public places should be worn in accordance with the requirements and maintain a social distance. Today, wearing a mask in public places is not only a civilized habit, but also a legal obligation that Shanghai citizens should adhere to.

How to use the rule of law thinking and the rule of law to regulate the public order of the city, so that the law can be dependent on, and the law is based on the law. It is an inevitable requirement and important content of the construction and management of modern cities. From the perspective of the refined goals of urban management, the accuracy and effectiveness of management methods should meet the basic requirements of standardized implementation, and the standardization of the means requires the establishment, sound, and perfect legal and regulatory system to enhance the particle size and refinement of legal resources With high rigorous rules and the spirit of the rule of law, it provides a solid institutional foundation and exquisite behavioral guidance for the efficient operation of urban management. On the one hand, we can rule the people and the people in accordance with the law, and use laws and regulations to restrict the behavior of citizens; on the other hand, in accordance with the right to rule, govern officials, regulate the behavior of government agencies and their public officials, and use laws and regulations to control the exercise of public power. It can be said that the process of continuous improvement of the rule of law in urban management itself is an important practice of the concept of "the people of the people’s city and the people’s city for the people".

The standardization of management methods is also conducive to overcoming the disadvantages of sports and empirical governance, and improving the long -term and stability of urban governance. The content of the standardized management methods also includes the clear division of the rights and obligations of various types of public affairs and the supply of public services, and the determination of organizational management and operating rules provides behavioral specifications for various governance subjects, and provides public rights of the public. Standards and basis, guide urban management laws and regulations to become social consensus and behavioral rules.

For the government, the rule of law of management methods lies in clarifying its responsibilities and their behavioral standards, accelerating the transformation of government functions, and promoting the original inherent leadership decision -making government to the legal decision -making government through the construction of the rule of law. For citizens, as the main body of the city, citizens have the right to also obliges to improve the literacy and legal awareness of the rule of law, can establish reasonable expectations for administrative processes and management effects, and achieve effective supervision of public administration. It can be seen that the rule of law is the core symbol of urban competitiveness and the dazzling business card for urban governance.

The ideal state of rule of law is "the law can be prohibited, and the law is prohibited without authorization." To achieve this goal, the lack of legislation, law enforcement, and law general law is indispensable. Especially for Shanghai with the inheritance of sea -faction culture, its regional culture itself has a basis for contract civilization.

Shanghai is the first city in the country to implement garbage classification. From July 1, 2019 to the present, it has formed a situation of Shanghai demonstration and onlookers in the country. For Shanghai, legislation is both the task required by superiors, but also the endogenous demand generated by garbage classification to a certain stage. Up to now, the "Regulations on the Management of Shanghai Municipal Lomitic waste" have been implemented for more than two years, and the garbage classification has entered the daily life of each Shanghai person. It shows the civilization of the city.

Case: Fine Management -Taking the "Regulations on the Management of Shanghai Municipal Links" as an example

From 2005 to 2010, the average annual growth rate of Shanghai’s domestic waste was about 3%, the average annual growth rate from 2011-2017 was 4%, and the annual growth rate after 2014 reached 5%. And the traditional garbage treatment method, whether it is incineration or landfill, will bring obvious problems: occupying tens of thousands of acres of land, mosquito flies fly chaotic, sewage overflows, smells of the sky, seriously pollute the soil and groundwater environment … The number of garbage is still threatening the lives of various wild animals, and the garbage in rivers and oceans invades the habitat of aquatic creatures, causing them to die by mistake and even species extinction. At the same time, the two evils brought by the waste incineration are one of the most deadly toxic substances on the earth. After the incineration is discharged and discharged, it can diffuse from a long distance. Once the pollutants enter the human body, they will stay for a long time and eventually cause cancer. "Garbage siege" has been "under the city."

Promoting garbage classification can effectively improve the efficiency of garbage treatment, reduce treatment costs, reduce land consumption and environmental pollution, drive circular economy, save resources, and turn waste into treasures, and have the benefits of social, economic and ecological aspects. However, in order to do a good job of domestic waste, we must change people’s behavior habits and require a long -term process. Refined governance of domestic garbage in other countries often go through decades or even longer efforts. Therefore, the legislative work of the garbage classification is not only the need to mobilize the entire force, but also the most powerful education and guidance of this work and the most powerful education and control.

On the basis of a large -scale questionnaire survey and full review, Shanghai people have reviewed and approved the "Shanghai Municipal Home Wurns Management Regulations" greater than January 2019. It is announced that it will be officially implemented on July 1, 2019. Enter the "hard constraint" era.

The legislation clarified several priorities in Shanghai’s garbage classification work. One is how to divide it? Shanghai has been exploring garbage classification since the 1990s. After several changes, in 2011, it was determined to be recyclable, harmful garbage, wet garbage, and dry garbage. During the review of the regulations, the Standing Committee of the Municipal People’s Congress designed a set of questionnaires for the general public, and the results showed that most citizens expressed their recognition of the "four -point method".

Shanghai domestic waste classification and launch guide

Who will control it? At the three levels of the city, district, and streets, the regulations stipulate the management model of "combination and block", and clarify the work content of the street office and the township people’s governments. One by one. For example, units and individuals who generate domestic waste are the responsible subjects of classification and distribution. They should put domestic waste to the corresponding collecting containers; each launching point shall establish a classification and distribution management responsible person to clarify their rights and obligations; For garbage, the receiving unit can refuse to receive it. If it does not make corrections within the time limit, it can be fined.

The third is how to do the source reduction? The regulations include specific matters including promoting product packaging materials and reduction of express packaging. For example, hotels must not take the initiative to provide disposable daily necessities, catering service providers and catering distribution service providers must not proactively provide free disposable chopsticks, puffing and other tableware. In Shanghai, when using APP such as "Hungry" or "Meituan", each merchant must provide special tableware options and give reminders to "provide on -demand".

Fourth, how to achieve "closed loop" management? The regulations strictly standardize and transport and transport, and clarify that the receiving units must use special vehicles and ships to implement closed transportation. Realization of the whole process.

After the "Shanghai Municipal Domestic Waste Management Regulations" was officially implemented, a public account article entitled "A picture to understand Shanghai’s domestic garbage classification" was crazy "swipe the screen" in the circle of friends. Someone teased that the "magic people" was "mad" by the garbage classification. Every morning, when they went out, they had to accept the soul torture of "what garbage was".

Mobilization and ridicule, but if you go to the community and ask "whether the garbage classification is good", even the seventh or eighty -year -old grandma will answer you: "Okay! Now the environment is so serious, Allah is obliged to contribute to environmental protection." Since the implementation of more than two years, garbage classification has entered the daily life of every Shanghai people. Everyone is proud of "division", ashamed of "indiscriminate".

Observing all corners of Shanghai, you can find many places that are changing because of garbage classification: Located on the coast of the East China Sea and 70 kilometers from the southeast of the city center -this "digestion" of about 50%of the domestic garbage terminal treatment in Shanghai The landfills have become the ecological protection display window of green surroundings; Xinyixiu Village, which has achieved "wet garbage cannot be out of the community", Aunt Hou voted to the wet garbage in the community’s trash tank, and the intensive processing of intelligent equipment was treated with concentrated treatment 4 hours later, it became organic fertilizer, and was taken home by Aunt Hou to raise flowers. At the Century Lianhua Luban shop after the "Plastics Limit Order", the counter was carefully prepared on the counter. Packing for customers to use …

Xinyu Liu Village "Wet garbage does not get out of the community"

The changes that occurred in factories, communities, supermarkets, and landfills are the true portrayal of the participation and control of the whole people. As of the end of 2020, Shanghai has initially established a full -process classification system to achieve 100%harmless treatment of domestic garbage. Both residential and unit domestic waste classification standards have doubled more than 95%, and the recycling rate of domestic waste resources has reached 38%. Garbage classification makes Shanghai more livable and more temperature.Please clickhereOr scan the code to buy to understand the exploration of refined city management in Shanghai:
