The Russian army is trying out rescue robots to rescue the wounded on the battlefield

Rescue robots are special robots used in the field of post-disaster rescue . Recently, the Russian army used rescue robots in military exercises, which attracted attention. Robots go to the battlefield to rescue the wounded by themselves. This is the most common rescue robot. As early as the beginning of the 21st century, China started the research and development of earthquake rescue robots, especially after the Wenchuan earthquake.

Rescue robots can be divided into many categories. Some can travel through the narrow gaps in the ruins after an earthquake, search for trapped people, and convey information to rescue workers for treatment; those with the ability to dig, crush, shear, expand, and saw off can assist in rescuing trapped people; rescue robots with the ability to carry and load can assist in transporting trapped people.

The rescue robot used this time is a multifunctional rescue robot. The equipment weighs 3-4.5 tons and integrates the rescue functions of various machines such as excavators, loaders, cranes, forklifts, aerial work vehicles, and various forms of life detection equipment functions.

It has six major functions: 1. Innovative structural design of multifunctional search and rescue equipment; 2. Lightweight design and manufacturing of key components; 3. Analysis technology of whole machine kinematics, dynamics and structural stability; 4. Bus management technology of multi-electromechanical system; 5. Electromechanical and hydraulic joint simulation technology of emergency rescue equipment control system; 6. Intelligent control of multifunctional rescue equipment;

The robot adopts a lightweight design, with double arms in front and folding arms in the rear. It has multiple hydraulic output interfaces that can be connected to generators, air compressors, oxygen generators, water pumps, various manual hydraulic tools and equipment, lighting, and charging.

It also has search and rescue functions, is equipped with a variety of auxiliary tools, and has long-distance, large-scale scanning search and almost all the functions of rescue machinery such as digging, crushing, shearing, expanding, sawing, grabbing, fork loading, lifting, lifting, pushing and pulling, supporting, and high-altitude operations. A single machine can replace more than 20 manual operations.

The robot is hydraulically driven, and its control system is based on the electro-hydraulic proportional system modeling, working arm motion analysis, and is developed based on the electro-hydraulic proportional control technology of the CAN bus. Equipped with a wireless remote control module, the robot has simplified operation and remote control functions. In addition, the control system has high reliability to ensure the safety of the robot during the rescue process.

Multiple cameras and sensors are installed at the end of each working arm, the vehicle body, the aerial work fence, the legs, etc. The end of the search arm is equipped with a microphone, a loudspeaker, a CCD camera, a life detector, a lighting lamp, etc., which can realize wireless communication between operators, rescue equipment, rescuers, victims and multiple rescue equipment.

my country's vigorous development of rescue robots is a microcosm of the continuous application of new technologies and equipment to rescue practice in recent years. Guided by rescue command, the national command cabin was independently developed. Through the four cabins of the on-site command center, rescue command center, communication control center and comprehensive office center, comprehensive functions such as consultation, decision-making and command, action management, information collection, analysis and judgment are realized. Through the public network, private network and satellite communication methods complement each other, and integrate high-point relay and other technologies, the network can still be connected and command can be smooth in the case of "power outage, circuit breakage and network disconnection".
