Pipe inspection robot
As a master of high-tech, the development of special robots is accelerating the arrival of a new round of technological revolution. Recently, at the 5th China-Russia Expo where the Yekaterinburg International Exhibition Center just ended, the special robots array of the Harbin Institute of Technology Robotics (HRG) was shocked by the audience, attracting attention both at home and abroad.
Not long ago, Ministry of Public Security Police Equipment Procurement Center announcement shows, HRG-reported EOD robots, fire-fighting robots, security robots, underwater robots to detect and police unmanned vessels are all included in the acquisition list. What are the hard work of these special robots to achieve the tasks that humans cannot accomplish? The Science and Technology Daily reporter recently visited the special robots division of the Harbin Institute of Technology Robotics Group in the Beijing Economic and Technological Development Zone.
No fear of danger, fire detonation, one shoulder
In the business department, the crawler-type red "Fire Guardian" robot has a spout at the top and is flexible in movement.
"When a fire breaks out, the fire field spreads out with raging flames. This baby-sized intelligent fire-fighting (fire-extinguishing) robot can spray water columns of 60 meters to 80 meters long and cover three or four floors." Harbin Institute of Technology Robotics Special Robots The person in charge, Han Zhenfeng, told the reporter.
The track of this fire-fighting robot is made of special materials and can withstand up to 750 °C; it can be used for remote walking, climbing, climbing and crossing obstacles; adapting to various environments, high temperature resistance, heat radiation resistance, rain protection , anti-chemical turbidity, anti-electromagnetic interference, etc., can continue to work all day.
"Fire-fighting robot's unique fog-passing and precision recognition function can be used as an advance soldier in firefighting operations to accurately identify the remaining personnel and fire source locations in the fire field, making rescue more effective and extinguishing fire more quickly. It is equipped with self-spray cooling. The system can maintain the ability to work long hours in the fire, even through the fire belt." Han Zhenfeng said.
Dangerous ammunition and explosives disposal is a very dangerous task. Manual explosion has great safety hazards. According to incomplete statistics, in the past 10 years, there have been about 12,000 safety accidents due to ammunition waste disposal in the past 10 years, more than 30,000 rows. Explosive experts and engineers are killed or injured. Therefore, some countries are stepping up the development of explosive robots.
"Based on this, this robot also has a major ability to probe explosives and has the function of 'explosion'. Its mechanical arm is flexible, light, flexible, stable, and adaptable. This is exactly what we are doing during the development process. One of the difficulties in breakthrough. It can move quickly on various terrains such as muddy roads, urban ruins, coal mines and oil fields. It can detect, grab, transfer, transport and destroy dangerous materials. It can replace security personnel to chemical flammable and easy The explosion site is a real investigation of suspicious objects." Han Zhenfeng said.
In order to make the product closer to the actual demand, the R&D team visited the investigation site of the multi-site police and adopted the intelligent modular design idea. The robot can install different sensor modules. If a module is broken, it can be quickly replaced, which is not only easy to expand and maintain, but also To a multi-purpose machine, it also effectively controls product costs. By remotely controlling the terminal system, the operation requires only one button to enable the robot to complete the various tasks required for the application site.
In-depth pipeline network to explore the city "thrombus"
The underground pipe network is like the “blood vessel†and “neural†system of the city, which is related to the safety of electricity, drainage, communication, and even the development of society and people's livelihood. However, there is no regular inspection of the urban pipeline system in China, and often the problem is solved after the accident, resulting in economic losses and even casualties.
Han Zhenfeng said: "In fact, such a difficult environment and difficult testing can allow robots to replace human resources and undertake inspection and maintenance of urban pipelines."
“The pipe inspection robot is small in size and can be drilled into underground pipes with a diameter of less than 80 cm. It is waterproof, high temperature resistant and light weight. It works continuously at a speed of more than 0.5 m/s in a working environment of -30 ° C to 50 ° C. "Han Zhenfeng introduced.
It is understood that, with reference to military standards, pipeline inspection robots can accurately determine pipeline leakage points through multi-sensor fusion technology, and detect whether there are cracks, deformation, corrosion, foreign matter intrusion, sedimentation, scaling and root barriers in the pipeline. , maintenance, regular inspections play an important role.
"Technically, this robot consists of a crawler crawler, control system and electric take-up car system. The crawler is equipped with a front multi-dimensional rotary pan/tilt camera, 470 line resolution, 10x optical zoom and white light high power. Halogen illumination, for direct and side view in the pipeline, flexible viewing, providing clear imaging results. At the same time, real-time display of video information in the pipeline and sonar analysis images on a high-resolution color monitor, and The detected conditions are provided to the inspection staff at a glance, thus forming an accurate and professional test report, providing a reliable basis for the later pipeline repair work," said Han Zhenfeng.
Dive into the bottom of the water salvage search and rescue is the most
The underwater robot, also known as the unmanned remotely operated submersible, is an extreme working robot that works underwater.
Zhang Chuan, head of research and development of underwater robots of Harbin Institute of Technology Robotics Group, pointed out: "In underwater rescue work, these factors such as complex water environment, rapid water flow and limited physical strength of diving personnel are easy to form a search and rescue obstacle. Under 30 meters of water is more There is a great security risk. Underwater robots can assist most divers in the rescue work, such as underwater search, video observation and target positioning, without the need to launch water.
Zhang Chuan said: "In the lake to salvage the target, you can use the police unmanned ship to search through a wide range of sonar. When several suspicious points are found, immediately send the underwater robot to the bottom of the lake to confirm it, and then use special tools. The target is salvaged out of the water. If the robot is needed to assist the public security system in finding evidence that plays a key role in criminal cases, such as the detection and extraction of underwater firearms and other murderous tools, it can be carried by a small robotic arm carried by the underwater robot. In the range of the load, directly grab the heavy objects of about 5-10 kg."
It is understood that the underwater robot is composed of two parts in structure. The first part is the underwater part, that is, the body part, including the propeller, the camera, the sonar system, the lighting system, etc. The second part is the water part, and the upper power supply and the control terminal are interconnected with the underwater robot through the umbilical cable to provide energy and control signals. The video signal and sensor signal collected by the robot body are also transmitted back to the control terminal through the umbilical cable.
“The great thing about underwater robots is that the underwater environment is more complex than in the air, so it requires a more capable ability to complete normal work. The complex intelligent control system and monitoring and identification system are underwater. The key technology of the robot ensures that the underwater robot can move normally and see the surrounding environment. Our self-developed hydrophobic imaging technology can increase the clarity of the image by more than two times." Zhang Chuan stressed.
Now some equipment that has been immersed in water for a long time, such as the gates of the reservoir, the dam body, and the bridge pier of the sea bridge, will have different degrees of surface corrosion, defects, cracks, and exposed ribs after several years of use. Processing will have huge hidden dangers.
“Special underwater robots will be used as a tool to carry appropriate observation and testing equipment into the bottom of the water, to check related problems one by one, and to transmit the obtained information back to the control terminal in time to provide first-hand information for the later maintenance program.†Zhang Chuan said.
