Boston Dynamics Spot the dog robot has set the precedent for personal pets that are way smarter than your average robotic toy. Unitree B2 has somehow taken the idea of a dog robot to the next level, and it is much more affordable to own compared to Spot. It is almost half the price of the Boston Dynamics’ innovation. Designed by the Chinese company, Unitree Robotics, the four-legged robot is superior in speed, agility, and maximum payload capacity.
Both these robotic dog rivals have their own set of advantages, but from a sheer owning point of view, the better bet is Unitree B2. Given its performance and mobility attributes, the robot is ideal for emergency situations or operating in hazardous environments like a fire breakout. That’s the reason the Chinese robotic firm has created a firefighting version of the B2 robot to assist the tactical response team.
Designer:
To give the robotic dog a promotion from the monotonous daily tasks, there are a few upgrades in place. These add-ons and improvements to existing hardware make it capable of taking on nature’s fury head-on. Modular design is the key as it can adapt to real-life situations, giving first responders the option to tailor B2 for the mission at hand. The quadruped is equipped with a powerful cannon capable of spraying water or foam to a distance of 60 meters with an 85-degree freedom to direct the front hose. That at a flow speed of 40 liters per second, to doze off even the most raging fires. The hose can activate the sprinkler mode to shower the robot with water if things get too hot to handle. B2 can do this in urban scenarios as well as rugged terrain, thanks to a better robotic DNA.
B2 firefighting robot has upgraded joints that perform 170% better than the regular B2 model. This gives the liberty to climb obstacles of up to 15 inches or climb steep stairs with an inclined of 45 degrees. Thus making the firefighting B2 no match to a human in dangerous, crumbled buildings, places with toxic gases, or burning hot, rugged ground in a forest fire. The robot can autonomously detach the fire hose supplying the water or foam after the task at a designated site is finished. B2 is completely dust and waterproof, which makes complete sense as it has to operate in very hostile environments. It comes with an air-blower unit that can be attached to extinguish forest fires safely by cutting the connection between flames and combustibles.
The quadruped robot will have to operate for long durations in tough missions, hence, Unitree has loaded it with a hot-swap battery system. Firefighting B2 has already shown what it is capable of during the Qingdao Firefighting and Rescue Support Team drill. To enhance the bot’s capability, there are advanced attachments including robotic arms, LiDAR systems, communication gear, and video feed rigs.
