Sounds cool. :-)

Many inventions were created with the inspiration from works of science fiction...

Frankly, I was telling myself it would only be a matter of time before we see such devices roaming around...

Although from a practical standpoint, I could see why a quatruped, or even an octoped robot would be better-suited for combat/rough situations. You could blow up one of the legs from an octoped walker, and it could keep on going, provided it's designed to adapt from eight to seven (or less) legs... Blast off one of the mecha's legs, and it'll topple right onto the ground...
