swissnex San Francisco and Long Now would like to invite you to the unveiling of Jürg Lehni’s Chalk-Drawing Machine at The Interval for a reception with the artist featuring live demonstrations throughout the evening.

The Long Now Foundation commissioned Jürg and his team in Switzerland to build a custom version of Viktor, his chalk-drawing machine, for their space as well as the software to interface with it. Long Now will also be working with Jürg to develop content for the robot and figure out how to make it a platform for use by visiting speakers and artists.

The design of the chalk-drawing machine is extremely elegant, using an unconventional system of pulleys that is driven by high-quality Maxon Swiss servo motors to triangulate the drawing tool. The motors are coordinated by an open-source controller developed by Jürg himself.

In 2013, swissnex San Francisco invited Lehni to participate in the TYPO conference, and in early 2014 swissnex facilitated his inclusion in the SFMOMA A+D Forum design fair with his spray painting robot, Hektor. During the same period, an earlier version of  Viktor was featured in an exhibition at SOMArts called All Possible Futures, curated by Jon Sueda of the California College of the Arts (CCA).
