Robovie: The Grocery Shopping Robot Assistant [video]
Robovie is a robot shopping assistant currently being testing in Japan. At home, shoppers build a shopping list on a mobile device, and once at the grocery store, the robot detects the mobile device and follows them around with a shopping basket, reminding them what's on their list and even making suggestions along the way. Also, it makes witty banter.
Mrs. Hasegawa, the 67-year old woman who shopped with the robot, said: "It's like being around the big shops with grandchildren. Lots of fun chatting with the robot." Robotwatch has a writeup (Google translation) and Quicktime videos, or here's a video from YouTube:
