| Ecological Robot (refers to a class of energetically autonomous robots that can remain self-sustainable by collecting their energy from (mostly) waste in the environment.

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. (from Wikipedia) LyuFi) | |||
