[VIDEO] Developers create a phone case that crawls to charger on its own!

The scientists at Seoul National University call their invention the "case-crawler."

Researchers in Korea have developed a case that helps a smartphone crawl to a charger when the battery is low. The scientists at Seoul National University call their invention the “CaseCrawler.”

The crawler’s pins can not only walk but can also climb over tiny obstacles such as books in their path. Once it is done crawling, the pins retract and go flat against the case, making it no different from an ordinary phone case.

It can carry a total weight of 300g, which is 13 times its own weight. This feature makes it capable of carrying more than an ordinary smartphone.

The researchers examined the crawler on a 190g smartphone, and it successfully carried the device to a nearby wireless charger. The video below shows the CaseCrawler in action.

Currently, the crawler can only scamper forward in the direction of a charging pad if set up on your desk. In the future, developers believe the miniature robot would be capable of returning to the owner when fully charged.

The technology is far from mass production right now, but the prototype shows promise, and further progress does not appear to be far.
