While many people are busy working on how to build robots capable of doing everything (and more) humans can do, few are considering the impact that creating a legion of robotic workers will have on the environment. Two university researchers aim to change this, by investigating how to build robots from biodegradable materials that will simply decompose at the end of their lives.
