3D-printable robot arm is a sign language interpreter

A team from the University of Antwerp is developing a robotic sign language interpreter. The first version of the robot hand, named Project Aslan, is mostly 3D-printed and can translate text into fingerspelling gestures, but the team's ultimate goal is to build a two-armed robot with an expressive face, to convey the full complexity of sign language.
There have been a number of technological attempts to bridge the gap between the hearing and deaf communities, including smart gloves and tablet-like devices that translate gestures into text or audio, and even a full size signing robot from Toshiba.
