Looks extremely useless compared to humans doing the real work of keeping the test fire from getting out of control before realizing once that hose is full of water, that machine does not have the weight to control the hose and pull more out as it moves to put out the fire.
The electro motors and power pack are not there.
I wanted to see something that used the water pressure flowing through it to power itself to be able to control the heavy stiff hose, and drag it. These 'dogs' can run at beyond human speed, and deliver bad stuff in what I hope never happens.
