EcoBot is short for Ecological Robot and it refers to a class of energetically autonomous robots that can remain self-sustainable by collecting their energy from (mostly) waste in the environment. The only by-product from this process is carbon dioxide, which would have been produced from biodegradation in the first place. This carbon dioxide production belongs to the immediate carbon cycle of our planet and does not impose to the already increasing problem of the greenhouse effect.
Autonomy
So far autonomy in robotics has been directly linked with the ability of agents to compute and execute tasks, i.e. follow a set of rules given in an algorithm, with minimum human intervention. This is classified as computational autonomy, however it does not necessarily take into account the problem of energy collection and management. Energetic autonomy, therefore, refers to the ability of artificial agents to remain self-sustainable, with minimum or no human intervention.
EcoBot-III
EcoBot-III was developed in 2010, as part of a European FP-6 funded project, by Ieropoulos I., Greenman J., Melhuish C. and Horsfield I and was the world's first robot to exhibit true self-sustainability, albeit in primitive form. 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 (Please click here to watch it in action http://www.brl.ac.uk/projects/ecobot/ecobot%20III/index.html). 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.

EcoBot-II
EcoBot-II, developed in 2004, by Melhuish, Greenman, Ieropoulos and Horsfield at the Bristol Robotics Laboratory (BRL) UK, was the first robot in the world to perform sensing, information processing, communication and actuation phototaxis, by utilising unrefined biomass. In fact, it consumed dead flies, rotten fruits and crustacean shells as the fuel and oxygen from free air as the cathode. EcoBot-II operated continuously for 12 days after having been fed with 8 houseflies of the species Musca domestica [Ieropoulos et al. 2005a, b; Melhuish et al. 2006].
EcoBot-II is the first practical example of a Symbot (symbiotic robot) that exhibited artificial symbiosis – the beneficial integration between the live microbial part and the artificial mechatronic part.

EcoBot-I
EcoBot-I, developed in 2002, by the same group of workers at BRL, UK, utilised sugar as the fuel and ferricyanide in the cathode, to perform phototaxis (i.e. move towards the light) [Ieropoulos et al. 2003a, b; 2004].
The two EcoBots do not employ any other form of conventional power supply and do not require any form of initial charging from an external source. Instead, they are powered directly by the onboard microbial fuel cells (MFCs). This is in contrast with Gastrobot, which although it was the first example of a practical application that employed MFCs, it used onboard conventional batteries and required initial charging from the mains.
