Light Painting Art Done Using Swarms of Robot Vacuum Cleaners

This light painting photograph was created by a group of students over in Germany using a swarm of seven Roomba automated vacuum cleaners. Each one had a different colored LED light attached to the top, making the resulting photo look like some kind of robotic Jackson Pollock painting. There's actually an entire Flickr group dedicated to using Roombas for light painting -- check it out of you have one of these robot minions serving you in your home.

Paparazzi Bot Prowls for Smiling Faces

The Paparazzi Bots are a series of robots invented by Ken Rinaldo, a faculty member in the Department of Art at Ohio State University. Each bot is autonomous, and moves about on a wheeled platform, using infrared sensors to move towards humans. It's goal is to take single photographs of people, and it makes decisions on whether or not to capture the photograph based on facial expressions of the subject. If you happen to be smiling, the bot is more likely to photograph you.
