Unitree has launched a modified model of its B2 quadruped aimed toward placing out fires. In a position to host numerous use-specific modules, the robodog hauls a strong water cannon high-flow and might function in excessive environments.
Although quadruped robots can tackle inspection, mapping and surveillance duties, they will additionally scout harmful environments in order that people do not should. Such is the case with the hearth rescue bots from Unitree, which might be geared up with surveillance modules to offer dwell video feeds to distant firefighters, permitting them to evaluate a state of affairs earlier than getting into.
Different modules mounted to its again can embrace a robotic arm, LiDAR sensors, comms gear and a water cannon with a spread of as much as 60 m (almost 200 ft) and a excessive circulation charge of 40 liters per second. The hose is hooked up to the rear whereas the enterprise finish might be angled as much as 85 levels to swimsuit the fire-quenching want. The system can use water or foam, and the quadruped can robotically uncouple the hose and probably transfer on to different duties with out lacking a beat.

This module additionally features a sprinkler system that is not designed to place out fires, however to maintain the robotic itself cool when throughout shouldn’t be. Which means the quadruped is dust- and waterproof, whereas composite metallic supplies for the physique additionally contribute to its excessive atmosphere readiness.
Yet one more module worthy of point out is an air-blower unit “to extinguish forest fires safely by reducing the connection between flames and combustibles.”

Unitree has additionally boosted joint efficiency over an ordinary B2 by 170%, giving the robodog additional climbing energy for tackling obstacles as excessive as 40 cm (15 in) and stairs with a 45-degree slant. And eventually, the hearth rescue bot advantages from a hot-swap battery system for prolonged use within the discipline with out compromising waterproofing.
Quite a few drills and demos have already taken place to show the robodog’s fire-fighting mettle, and a pair not too long ago joined the Qingdao Firefighting and Rescue Assist Staff in an official capability. Items are actually out there on the market, although we have no phrase on pricing. The video under has extra.
