Of all the things a robot armed with a chainsaw could carve, a log seems the most benign. Berlin, Germany based company Echtwald started a program with the Karlsruhe University of Arts and Design to create what is known as the 7xStool. Designed by Karlsruhe alumni Tibor Weissmahr and Tom Pawlofsky, the 7xStool is produced two at a time by the unnamed (but ever-powerful) chainsaw robot seen above.
The robot made an appearance in Cologne for the Passagen 2013 design week where it would publicly carve logs into stools twice daily. The 7xStool is part of a art collection called kkaarrlls, which highlights student work from the Karlsruhe University. Because of the robots millimeter precision and clever programming, the entire process leaves essentially no scrap parts. The stools carved in live performances at Passagen were auctioned off to audience members.
