Special-Purpose Robots Take on High-Risk Missions, Withstanding 500°C and Pulling 6 Tons

Recently, a number of Chinese special-purpose robots have drawn widespread attention online. A 'robot wolf' that can withstand temperatures up to 500°C went deep into a fire scene and transmitted reconnaissance footage. A flying lifebuoy developed for Hangzhou police traveled autonomously to a drowning site at a speed of 14 meters per second to assist in the rescue. Many netizens commented that scenes once found only in science fiction have now entered reality.

On September 20, the Zhejiang leg of the first Intelligent Robot Application Skills Exhibition, under the theme 'Competing for the Intelligent Future,' opened in Yuhang District, Hangzhou. More than 300 robots gathered for the showcase. Besides the humanoid robots familiar to the public, the exhibits featured many robot 'new colleagues' with diverse forms.

They do not look like humans, but they are still robots. Their design puts the task first: wherever the environment is dangerous or difficult for humans to reach, they go. Their appearance is entirely subordinated to practical operational needs.

These special-purpose robots of various shapes are continuously taking on urgent, difficult, dangerous, and heavy tasks. They include a three-point balanced counterweight fork robot capable of lifting 1.5 tons, a powerful machine that can pull 6 tons, and a 'wildcat' robot that moves through complex environments and undertakes inspection and security missions.

A magnetic wall-climbing steel formwork cleaning robot weighs less than 23 kilograms, yet it can attach itself to walls, crawl autonomously, and complete tasks such as grinding and cleaning. It has already been applied in engineering projects including the Pinglu Canal and the Xiamen-Jinmen Bridge.

The firefighting version of the Andi robot once participated in support operations for the Beijing Winter Olympics and Winter Paralympics, and it was also deployed at the 5,200-meter base camp of Mount Everest. A water cannon robot has a maximum range of 60 meters and can switch between a straight water column and a wide-angle spray mode according to the needs of a fire scene. Hangzhou's Hangjing Zhixing wheeled robot can cruise efficiently on roads and identify violations such as running red lights and not wearing helmets.

The design logic of special-purpose robots is different from that of humanoid robots. The goal of humanoid robots is to adapt to human environments, use human tools, and perform tasks that humans can do. The goal of special-purpose robots is to go to places humans cannot go and do things humans cannot do.

In fire scenes, high temperatures, toxic gases, and collapse risks, as well as complex underwater and underground environments, are all places where humans cannot remain for long. Special-purpose robots do not need to look like humans. What they need is high-temperature resistance, corrosion resistance, waterproof and dustproof performance, wall-climbing ability, and obstacle-crossing ability.

These capabilities correspond to concrete physical indicators: 500°C tolerance, 6-ton traction, and 60-meter range. Each one directly corresponds to a type of operational scenario. Cool stunts do not mean immediate deployment. For a robot to truly enter real combat, it still needs continuous iteration and optimization based on actual working conditions. The value of a special-purpose robot does not lie in whether its shape resembles a human, but in whether it can work stably in real high-risk environments.
