We saw some early attempts of "Feral Robots" sniffing out pollution
in a London park, but the project seems to have grown substantially since then, with Natalie Jeremijenko peddling her Feral wares to college students across the country. Most notably, the bots have advanced from simple RC cars to cute little refurbished dogbots, for maximum media exposure, minimal environmental impact, and a bit of fun. They're also working on getting the robots to work as "packs" for coordinated pollution patrol, and better mapping of the data they collect. Check out the video of a UCSD student's "ChemHound" after the break.
