This bot's name says it all: 'Chaos'

We've often fantasized of having a robot that could act as a personal bodyguard or bully, depending on what the situation called for. But most of our concepts had been on a relatively modest scale--until we saw the "Chaos."

This is the machine you call upon for duties that are beyond the abilities of mere humans. As Tech Digest says, the Chaos is equally adept at discarding bombs and handling hazardous materials, moving "silently over unstable ground" on its rubberized track treads. We imagine that it would be pretty effective against those pesky spy bots too.
