Drones With Claws Perch on Arctic Icebergs
AI-summarised brief · reviewed before publication
Canadian researchers have created the Ice Dart, a 2.65 kg drone equipped with retractable micro‑spine claws that can perch on icy slopes up to 58 degrees. Tested on Iceland’s Fjallsjökull glacier and nearby icebergs, the drone landed at speeds of three metres per second, maintained a 100 % success rate in 30 km/h winds, and held position using two spines per leg that penetrate the ice. The landing gear absorbs impact with friction‑torque disks, lowering the centre of mass and allowing passive engagement of uphill and downhill claws. The team, led by Université de Sherbrooke engineers, published the results in IEEE Transactions on Field Robotics, noting that perching reduces power use, noise and thermal/RF signatures, enabling multi‑day observation of remote ice features for scientific research.
💡 Why It Matters
- · By turning icebergs into stable platforms, the Ice Dart turns a fleeting aerial snapshot into continuous, low‑impact monitoring, a capability that could reshape Arctic data collection.
