Although the Ecobot III is capable of eating and excreting, you wouldn't guess its capabilities solely by its appearance.

Developed by researchers based out of UK's Bristol Robotics Laboratory, the Ecobot III can actually run unsupervised for an entire week. The Ecobot III is especially remarkable because it employs microbial fuel cells that allow it literally eats, digests and excretes via a metabolic process that isn't energy intensive.
