Bristol University’s Robotics Laboratory has developed the ‘soft’ robot which feeds on living organisms, can digest them, and even ‘die’ at the end of its lifespan.

The robot, which is water-based, consumes algae through its soft polymer membrane mouth.

The mechanical being has a microbial fuel cell in its ‘stomach’ which can break down organic matter and convert it into energy to sustain itself.

The hope is the machine will be used for environmental clean-ups in the future.
