A chainsaw-wielding industrial robot arm might be an unusual way to demonstrate modern design practices, but that’s what featured in the exhibition 7xStool by Tom Pawlofsky and Tibor Weissmahr.The piece demonstrated how a KUKA industrial robot can carve a stool and table in around 30 minutes from one piece of wood. Sure, it hasn’t quite got the delicate artistry of an exquisitely carved piece of furniture by a human hand, but for such an imposing piece of kit it’s pretty nimble and precise—so you’ll forgive the rough edges. After the robot showed off its carving abilities at the Passagen 2013 – Interior Design Week in Cologne, audience members could purchase the products.It’s an impressive display of how industrialized design processes can produce precision carving with minimal wastage, and you can’t deny its machine-skill at taking a hunk of tree and turning it into some furniture.[via Design Playgrounds]@stewart23rd
