What is "ecobot"

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 material, mostly waste matter, in the environment. The only by-product from this process is carbon dioxide, which would have been produced from the natural biodegradation of the fuel regardless. 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.
