Energy-Autonomous Robots Closer to Reality

Robots that inspect dikes and other sea defence structures are extremely useful — but require a large amount of energy. Researcher Douwe Dresscher, at the University of Twente in Enschede, Netherlands, has developed a smart gear box that stores energy in a mechanical rather than electrical way.

This controlled passive actuation stores energy in a spring instead a large battery pack. Future research may also enable these robots to obtain energy from other sources, such as wind and solar.
