Thanks for your interest in my article. Some readers were asking why the wireless/network would get jammed. The robot is a Hitachi robot being demonstrated at a Hitachi facility. And so the workers (who are working in sections other than the robot section) are all logging on and accessing the intranetwork server to look at email, surf the Net, etc. The problem was that the engineers had never tested the robot during lunchtime. In many Japanese companies, people often take breaks en masse. They weren't sure if the problem was wireless related or Network related, or both, but they said it was because there was too much traffic.
