Researchers at Canada’s Université de Sherbrooke have developed the Ice Dart, a multirotor drone designed to land on steep, slippery ice using retractable claws inspired by cats. This innovative landing gear allows the drone to maintain stability on slopes of up to 60 degrees and withstand winds exceeding 30 km/h, as demonstrated in tests conducted on natural icebergs and glaciers in Iceland.
The significance of the Ice Dart lies in its ability to expand the operational capabilities of multirotors in challenging environments. By employing friction-based landing gear and reverse thrust, the drone can absorb impact and secure its position on steep ice, making it suitable for various applications such as iceberg tracking, maritime safety, and environmental research. This advancement could enhance the utility of small drones for sensing missions, allowing them to conserve energy while remaining stationary.
Looking ahead, the Ice Dart represents a promising development in drone technology, particularly for operations in Arctic regions. The research team, consisting of Isaac Tunney, John Bass, and Alexis Lussier Desbiens, continues to explore innovative landing solutions for multirotors, potentially paving the way for further advancements in drone capabilities in extreme conditions. No further timeline was disclosed at the time of publication.
Editor's Note
The development of the Ice Dart drone highlights the increasing importance of specialized landing technologies in the robotics sector. As industries seek to utilize drones for more complex tasks in challenging environments, innovations like those from the Université de Sherbrooke will play a crucial role in expanding operational capabilities and applications in fields such as environmental monitoring and Arctic exploration.
