Wire Cutters

Two robotic devices are part of a mining operation. At first they butt their robotic heads, competing over what was available. The little guy, however, has a kind of infrared ability to discover the green minerals they are after. So when they work together, the big guy crushes the rock and the little one extracts the minerals. The problem is that even between machines, apparently there is greed; and that is what proves an undoing.
