With the legality all sorted out. What's been making headlines this week is a Unitree Go2 quadruple robot equipped with a flamethrower. 

"Thermonator is the first-ever flamethrower-wielding robot dog. This quadruped is coupled with the ARC Flamethrower to deliver on-demand fire anywhere!" Throwflame, the company behind the robot flamethrower, wrote on its website. 

Called the "Thermonator," the flamethrowing robot retails for $9,420 and can shoot napalm upwards of 30 feet. 

Throwflame says Thermonator is mainly used for "wildfire control and prevention," "agricultural management," "ecological conservation," "snow and ice removal," and "entertainment and SFX." 

Over the years, we have covered the proliferation of this technology, from 'cute' dancing robo-dogs from (Japanese-owned) Boston Dynamics to the Chinese version of 'spot' with a machine gun strapped to its back. 

Even an armed robo-dog deployed by a drone.
