Watch this crash-proof drone explore an ice cave

Heading into the abyss, the Gimbal is a drone that can venture where humans dare not go. Its makers recently partnered with a mountain rescue team to explore ice caves in the Swiss Alps. Protected by a shock-absorbing elastic frame, it bounces off obstacles as it navigates the narrow crevasse. The gyroscopic stabilisation system built in to the drone keeps it on course, despite the bumpy ride. Jan 27, 2016
