 This robot was capable of operating within an enclosed environment for 7 days, by collecting its food and water from the arena environment, metabolising these through the collection of 48 small-scale Microbial Fuel Cells and excreting the waste by-products at the end of the day.This work was presented at the Artificial Life XII Conference that was held in Odense, Denmark between the 19–23 August 2010 and the scientific paper (Ieropoulos et al.2010) is published by the MIT Press.
