As a "smart weapon" for dealing with complex disaster scenarios, demolition robots play an irreplaceable role in disaster rescue such as earthquakes, collapses, and fires due to their intelligence and high adaptability. It deeply integrates mechanical operations with intelligent technology, which can not only break through the limitations of harsh environments, but also accurately and effectively complete demolition tasks, buying valuable time for rescue.

　　1、 The 'wisdom' core of dismantling robots: technology empowers rescue

　　The "intelligence" of dismantling robots is mainly reflected in the collaborative operation of perception, decision-making, and execution, relying on various technologies to adapt to complex scenarios:

　　Environmental perception technology: By equipped with infrared thermal imagers, high-definition cameras, gas sensors and other devices, real-time temperature, image, gas composition (such as methane, carbon monoxide) and other information of the disaster site can be captured. It can even penetrate smoke, debris gaps, locate trapped personnel or identify potential hazards (such as flammable gas leaks, structurally unstable areas).

　　Intelligent decision-making system: Based on perceptual data, combined with preset rescue rules and algorithms (such as "obstacle avoidance path planning" and "demolition force adaptation"), it autonomously or remotely determines the operation plan. For example, when facing concrete debris, the system will automatically adjust the breaking force of the robotic arm based on the structural hardness feedback from sensors (to avoid excessive force causing secondary collapse); When encountering narrow passages, autonomously plan the extension angle of the robotic arm to avoid collision with obstacles.

　　Accurate execution technology: relying on high-precision hydraulic drive and multi degree of freedom robotic arms (usually 6-8 degrees of freedom, with flexibility similar to human arms), to achieve various breaking and dismantling actions such as "cutting, slicing, colliding, and pulling". Some high-end robots are also equipped with a "force feedback device" - when the robotic arm comes into contact with a soft object (such as a suspected human body), it can immediately sense and stop working, avoiding accidental injury to trapped personnel.

　　2、 Coping with complex disaster scenarios: targeted solutions to rescue pain points

　　Complex disaster scenarios, such as earthquake collapses, chemical plant explosions, and high-rise building fires, often involve environmental hazards (high temperatures, toxic gases), narrow spaces, and complex structures. Traditional manual demolition not only has low efficiency, but may also put rescue personnel in danger. Demolition robots can target and overcome these pain points:

　　High risk environment replacement operation: At the scene of a fire, robots can withstand high temperatures above 800 ℃, enter areas with dense smoke, use hydraulic cutting to break burnt steel bars, break doors to open up passages, and avoid firefighters being unable to work up close due to high temperatures and suffocation risks; In chemical plant leakage accidents, it can continue to operate in toxic gas environments, dismantle damaged pipelines, transport hazardous materials, and reduce personnel exposure risks.

　　Accurate demolition of narrow spaces: After earthquakes, the ruins often form "gaps only tens of centimeters wide" that cannot be entered manually. Small demolition robots (such as tracked robots weighing only 200-500kg) can flexibly shuttle through the tracks. After folding, the robotic arm can penetrate deep into the gaps and use a micro hydraulic pick to peel off debris layer by layer, or use a cutting saw to cut through obstacles, opening up a survival passage for trapped people.

　　Complex structural safety operations: Faced with "unstable building structures" (such as tilted floors, broken bridges), robots monitor the vibration and displacement data of the work area in real time through structural sensors, and adjust the work rhythm in combination with intelligent decision-making systems - for example, first reinforce and dismantle the "load-bearing columns" (remove redundant structures but retain load-bearing capacity), and then gradually clean up the surrounding debris to avoid overall collapse caused by blind demolition.

　　3、 Typical application case: from "laboratory" to "rescue site"

　　The value of the demolition robot has been verified in multiple actual disaster rescue operations

　　In the "7 · 20" rainstorm disaster in Zhengzhou, Henan Province in 2021, part of the underground garage was blocked due to ponding and collapse. The demolition robot waded through the crawler (some models have waterproof grade of IP67, and can operate in 1m deep water), entered the garage, cut the deformed garage door with hydraulic pliers, and opened drainage and rescue channels with pumping equipment.

　　In the rescue of building collapses, a certain "dual arm demolition robot" once used "dual robotic arms to work together" - one arm used a support device to fix an unstable crossbeam, and the other arm used a demolition hammer to clean up the debris below. In just 30 minutes, it opened a passage leading to trapped people, while traditional manual demolition of similar scenes usually takes 2-3 hours.

　　4、 Future trend: smarter and more collaborative rescue 'partners'

　　With technological iteration, dismantling robots are developing towards the direction of "more autonomy, multi machine collaboration, and functional integration":

　　Autonomous upgrade: Introducing AI big models and reinforcement learning technology, allowing robots to "autonomously learn" the operational experience of different disaster scenarios - for example, by analyzing thousands of collapse rescue case data, automatically optimizing the "priority order" of debris demolition (clearing non load bearing structures first, then processing load bearing components), reducing dependence on manual control.

　　Multi machine collaborative rescue: In the future, a collaborative team of "demolition robots+reconnaissance robots+transportation robots" may be formed - reconnaissance robots first go deep into the ruins to locate trapped personnel, and transmit real-time location information to the demolition robots; After the targeted opening of channels by the demolition robot, the transport robot carries emergency supplies into, achieving seamless integration of the entire process of "positioning demolition rescue".

　　Function integration and expansion: In addition to demolition, some robots have begun to integrate functions such as "fire extinguishing", "lifting", and "temporary support". For example, during demolition, fire extinguishing agents can be sprayed through the nozzles carried by the robotic arm, or inclined walls can be temporarily fixed with support arms to further improve rescue efficiency.

　　In short, the "intelligence" of the demolition robot lies not only in its advanced technology, but also in its ability to "tear open the gap of hope" in complex disaster scenarios that are difficult for humans to reach in a "safe and effective" way. With the continuous development of technology, it will become an indispensable "steel comrade" in disaster rescue, providing a more solid guarantee for life rescue.
