Damien Gaudry never took a course in sign language, but that didn’t stop him from wanting to build an instructional tool that could lend a hand to children who want to learn.

Gaudry and two other Georgia Tech graduate students – Cindy Perreira and Russell Marzette – built an 18-inch tall robotic hand that could eventually sign the 26 letters of the English alphabet.

cool I wonder what has become of this since then.....
