Technology is the core driving force for social development. Human society is gradually moving towards a more intelligent era with one round of technological revolution after another. In the inspection and testing industry, artificial intelligence and robotics are also effective driving forces for the transformation and upgrading of the industry.
In recent years, the core technology of robots has made significant breakthroughs. In the past, traditional industrial robots mainly followed a series of control instructions to complete tasks. With the development of artificial intelligence technology in areas such as perception, human-computer interaction, action control, and intelligent decision-making, robots are gradually being upgraded. For example, robot vision can enable sorting robots to recognize objects more accurately, and the sensing system can sense the surrounding environment.
According to statistics from the Ministry of Industry and Information Technology, my country's industrial robot production in 2020 was 237,068 units, a year-on-year increase of 19.1%; the operating revenue of industrial robot manufacturing enterprises above designated size nationwide was 53.17 billion yuan, a year-on-year increase of 6%, and the total profit was 1.77 billion yuan, a year-on-year increase of 1.77 billion yuan. It fell by 26.9%, and the decline narrowed by 24.4 percentage points compared with the first three quarters of last year. In December 2020, the national industrial robot production reached 29,706 units, a year-on-year increase of 32.4%. With the rapid development of advanced technologies such as artificial intelligence, robots have rapidly penetrated from the industrial field to the service industry. Service robots have shown a broader market space than industrial robots.
In addition, artificial intelligence is also developing at a rapid pace. Recently, IT and Internet companies in the United States have increased their investment in the fields of robotics and artificial intelligence, including multinational companies such as Google, FaceBook, and Microsoft. Our country has also included the term "artificial intelligence" in the national "14th Five-Year Plan" outline. Artificial intelligence has entered an inflection point of explosive growth.
So, what is the inevitable connection between robots, artificial intelligence, and the inspection and testing industry? Judging from the current development situation, my country's inspection and testing marketization mechanism is taking shape, domestic third-party testing is gradually liberalized, and everything is showing a trend of entering a better environment. But at the same time, relevant people also found that the concentration of the inspection and testing industry is low, with state-owned, foreign-funded, and private inspection and testing institutions dividing the market. The inspection and testing industry urgently needs to integrate resources through mechanism reform and technological innovation. Labor-intensive, The degree of automation, intelligence and standardization also needs to be further improved.
As labor prices rise, the "demographic dividend" of China's manufacturing industry is disappearing. At the same time, technological progress and industrial upgrading have led to the gradual reduction of "machine" costs, and "machine substitution" has become a new development trend. Inspection institutions such as SGS have successively developed intelligent inspection systems based on robots. Taking advantage of the advantages of robots, extremely high efficiency, accuracy and consistency can be achieved, while effectively reducing the impact of manual operations and human errors on inspection quality and efficiency.
In addition, the use of intelligent robots is particularly important when labor intensity is high and the environment is harsh. For example, in container inspection, quarantine and fumigation processing, the intelligent mobile robot platform can replace manpower to complete the delivery, concentration detection, environmental residue detection and other tasks of fumigants such as methyl bromide, phosphine, and ethyl acetate, freeing workers from toxic and harmful risks and Freed from harsh environment.
Based on the combination of artificial intelligence and the inspection and testing industry, people use VR, AR, MR and other technologies to form a new inspection and testing training and certification system. The inspection and testing training and certification model based on the new model of artificial intelligence will bring development opportunities to the inspection and testing industry, and has broad application prospects in observational learning, operational learning, social learning and research learning. The broad prospects of the inspection and testing market further highlight the necessity of leading the industry towards intelligence, improving inspection accuracy and efficiency through intelligent collaborative robot operation, extending the value chain of third-party inspection with the help of intelligence, and providing first-hand production for relevant industry decisions. Information will effectively promote the reform and rise of the inspection industry. In the future era of Internet big data for inspection and testing, if you want to be a trendsetter of the era, you must create the core competitiveness of "I have what others don't have, and I am one step ahead, and I have expertise and skills that are superior to others" in order to remain invincible.
Today, there are roughly three options and paths for intelligent testing laboratories:
A. The task is single and the types of instruments and equipment used are not many. There are related instrument and equipment manufacturers that provide a variety of optional integrated system solutions to build integrated experiments. The laboratory is intelligent;
B, the laboratory intelligent robot/system replaces the staff, and according to intelligent testing methods, procedures, and processes, the robot realizes the operation of instruments and equipment to form an intelligent laboratory;
C, AI technology has been integrated, Empowering the instruments and equipment used, an artificial intelligence robot/system can completely replace the staff, or even replace researchers and experts, to form and achieve a completely artificial intelligence laboratory.
Robots are generally divided into service robots and industrial robots. Service robots mostly refer to robots used to serve human life needs, while industrial robots are generally used for production needs. The robots in this article refer to industrial robots. Although they have different shapes and appearances, they are all very important tools for realizing laboratory automation. Usually we use degrees of freedom/joints to label robots. Similar to human arms, the more degrees of freedom/joints, the better the flexibility. In domestic laboratories, we can often see robots. In the field of scientific instruments, many companies have launched robots with different functions. We will introduce them with examples and conduct a brief analysis.
The liquid handling robotic arm used in Note 2 of Tecan’s fully automatic liquid handling workstation is a common three-degree-of-freedom robot form in clinical practice. Its advantage is high-throughput pipetting, which can process many samples at one time, and can even add 3 robots. Arm (mechanical gripper) is used to increase sample processing speed, which can greatly improve work efficiency and pipetting accuracy.

Thermofisher’s SCARA robot arm is different from the robot arm in the picture above which only has 3 degrees of freedom. This SCARA robot arm has 4 degrees of freedom Note 3. It is worth mentioning that the robotic arm is equipped with a visual part that can perform visual teaching, which is very friendly to the experimenter's operation.

In addition to a few manufacturers developing their own special manipulators, more companies choose to use general-purpose manipulators with very mature technology on the market. Like the robot researcher mentioned in the previous article, they use a 7-axis robot. Below the robot is a positionable control cabinet. The robot has 7 degrees of freedom, is very flexible, and is relatively expensive.
Shimadzu also recently launched a direct reading/fluorometer automation system using a general-purpose manipulator Note 4. The XYZ manipulator has three degrees of freedom, which is sufficient for some processes in the laboratory and is cost-effective. It can be used for handling and moving samples at a given location. The six-axis manipulator has 6 degrees of freedom, so it has good flexibility and speed. It has a wider range of applications and can complete more complex processes and work. The general reach speed is 2m/s.

In addition to analytical instrument companies, many equipment integrators are also actively deploying laboratory robots. For example, last year, Alfa Smith used a six-axis manipulator to complete the sample transfer process in the smart laboratory integrated by Conch Cement, and finally completed the sample testing.

Some robots have already shined in different fields. Although they are not yet used in laboratories, they have great application prospects for future smart laboratories. Let’s give a simple example below. introduce.
ABB's two-arm robot YuMi is a human-machine collaborative robotic arm. Different from ordinary robots, the robot has 14 degrees of freedom. It is very fast and flexible among collaborative robots. This will have advantages in handling some complex actions in future laboratories.

Parallel robots, commonly known as spider hands, are generally used to sort products on the assembly line. With the vision system, the spider hands are even more powerful and the sorting speed is very fast. This robot is suitable for future sorting in pipeline inspection by third-party inspection agencies, which can significantly reduce labor costs.

Hundreds of AGV cars running around in large logistics warehouses are also a hot type of robots at the moment. Similar transfer robots have been deployed in some third-party testing institutions. The entire process from warehousing, consumables, samples to testing can be completed by such robots, and the accuracy and efficiency will be greatly improved. Traditional specimen transfer within the laboratory is generally carried manually. This method is inefficient and requires manpower. For some laboratories with short TAT time requirements, frequent specimen transfer requirements, and relatively large space, intelligent robots are used. The transportation system can effectively solve such problems, help improve work efficiency, and ensure TAT. The intelligent robot specimen transportation system integrates sensor technology, mobile technology, operation control technology, artificial intelligence and other technologies. It has the visual sensors, auditory sensors and tactile sensors of human eyes, ears and skin. Through these systems, it can perceive the environment and make dynamic decisions. and planning, implementing behavioral control and task execution.
