These Adaptable, Self-Replicating Robots Surely Won't Tear The World Apart ... Right?

•, By Mary Beth Griggs

Watching the University of Oslo's three-limbed robot squirm across the floor like a dismembered starfish brings to mind shudder-inducing flashbacks of Stargate SG-1. More particularly, visions of SG-1's creepy-crawly nemesis, the Replicators, spider-like robots capable of well...replicating themselves...but also able to learn from their surroundings, adapt and generally tear apart entire worlds (or spaceships).

But surely, the good folks at the University of Oslo wouldn't be doing anything like that. Right? RIGHT? Oh wait, that's exactly what they've figured out how to do, minus the whole tearing-apart-everything-in-it's-path thing.

So, we've got that going for us.

The robot in the video below is part of a third generation of robots capable of adapting to their environment. To build it, researchers used a computer program to design robots within selected parameters. They could tell the program they wanted a small robot capable of moving at a certain speed and able to climb over boulders, and the computer program would come up with designs. Those designs would then be pitted against each other in a virtual death match to see which ones would best meet the needs input by the researcher. The design that performed the best in the computer simulations would then be produced on a 3-D printer, and continue testing in real world simulations, trying to perfect itself even more. If the robot is damaged or figures out that it needs a new part, it can either print a new one, or figure out how to get along without it.
