Uncanny Vallery in Richardson Texas

From the Visual Science blog, Life and Love in the Uncanny Valley:

David Hanson’s robots are by now somewhat familiar faces, including his Einstein robot currently being used as a research tool at Javier Movellan’s Machine Perception Lab at UCSD, and the punk rock conversationalist Joey Chaos. A less familiar face is that of Bina Rothblatt, the blonde at the end of the table in the above photograph. Bina is a robot commissioned by Sirius Satellite Radio inventor Martine Rothblatt to look like her beloved wife.

Hanson Robotics is in a house in the neighborhood where I grew up in Richardson, Texas. They’re doing some interesting work in robot aesthetics and materials, crafting convincing android-type replicants in a studio environment that’s busy around the clock. Flickr user steevithak has a nice photo set up of some of the robots they were tinkering with in 2009.

The GML Robotagger: Automated Calligraphy

GML (Graffiti Markup Language) drawings from are converted into DXF via a small Processing utility. Motion paths for a robot arm are developed from these DXF files using Rhino and MasterCam. The ABB IRB-4400 series arm is wielding a 2″ Montana Hardcore marker. Developed 11 January 2010 by Golan Levin and Jeremy Ficca in the CMU Digital Fabrication Laboratory (dFAB).

Concept: Evan Roth, F.A.T. Lab
Programming & Production: Golan Levin
Machining & Motion Planning: Jeremy Ficca

Co-produced by the CMU STUDIO for Creative Inquiry and the CMU Digital Fabrication Laboratory, in cooperation with FAT Lab and For more information please see
