I saw this robot at Kinetica. It was not very impressive. First of all, the hardware seemed poorly designed. It was incredibly shaky. When it drew a square around an image, the result were four wobbly lines that did not even connect.
The software, of course, is the more interesting part - and a complete mystery. They had a screen showing a program doing edge detection or something similar on a face. They had a camera that was supposed to capture visitors and draw their portraits. Other than that, nothing was written anywhere about how the software works.
They had some portraits hanging on the walls that looked really nice. But all the ones the robot drew live while I was there came out as a wobbly mess. Maybe it was broken or something... this was on the last day of the exhibition, it could have worn out I guess.
