Projecting a Human Face

Researchers at the Technische Universitaet Muenchen (TUM) Institute for Cognitive Systems are working with Japanese scientists to give robots a human face through the use of 3D projection technology.

They use a projector to beam the 3D image of a face onto the back of a plastic mask, and a computer to control voice and facial expressions. The result is what they have dubbed "Mask bot" which can reproduce basic dialogue and appears to be a tremendous step in the advancement of human-robot communication. The hardware includes a semi transparent mask, a portable LED projector mounted behind the mask, and a fish-eye conversion lens attached to the projector.
