I also wonder if it's a robot or just a short guy in a costume.
Here is your link.
According to the article it is named Soorena-2, after an ancient Persian warrior. At least it wasn't named "Muhammed Atta".
The article also quotes a press release in Iran:
"Such robots are designed and developed to be used in sensitive and difficult jobs on behalf of a person or as help."I guess that there are some parts of assembling atomic bombs that are dangerous and a robot would be perfect for that.
