Maybe the motion detectors could spin around the greeter in circular fashion? That could work. And as the motion detectors would move around the Greeter itself, it would kind of expand outwards and then retract inwards. Imagine a whole small army of these things surounding these big mine fields. Not only you have the mines to worry about but the Greeters that are moveing in batween them. Say these Greeters are programed to menuver inbatween mines sort of like smart Greeters. Sound hard? You betcha! Talk about a good Oddworld styal challenge for ya ya know? Because as soon as you move in the beam you not only get zaped but also set off a chain reaction of explosions killing say you and Mudokin Scrubs in the process. I like it! Saveing Mudokins out of that would be tricky.
