a construction robot in switzerland has created a temporary pavilion using nothing more than loose stones and string. the structure, which is supported by a series of stable columns, is being presented by resear­chers at ETH zurich as part of an exhibition in the swiss city of winterthur. the scheme comprises 30 tonnes (30 tons) of loose stones, which the robot has bound together using 120 kilometers (75 miles) of string.

the ‘rock print pavilion’ is part of an exhibition titled ‘hello, robot. design between human and machine’, currently on view at winterthur’s gewerbemuseum. the construction robot, known as the ‘in situ fabricator’, worked for a total of four weeks to build 11 three-meter-high (10 ft) pillars. to support the pavilion’s eight-tonne (8.8 ton) steel roof, ETH zurich’s researchers implemented a technique known as ‘jamming’.

the ETH research project ‘design and robotic fabrication of jammed architectural structures’ focuses on the robot-based assembly of simple, loose, and granular base materials. when combined with the arrangement of string between the gravel layers — which is continuously calculated by the robot — the stones interlock together. this creates a stable, highly durable structure. recycling is also embedded into the project as the components can be easily dismantled and the material reused.

  • Was it four weeks because he had to load 8T of stone with a bucket …climbing the ladder? Is the dribble at the base where the string did not work? Many questions…
