Scientists Develop Drone Technology to Pollinate Flowers Automatically
Key Takeaways
- Japanese scientists have built a drone that can pollinate lily flowers using horse hair and gel
- Future versions may use GPS and AI to autonomously navigate pollination paths
- The technology aims to offset the severe decline in global bee populations
The world’s bee populations are shrinking rapidly due to pesticide use, climate change, and habitat loss, putting pollination — a vital process for plant reproduction — at risk. In response, researchers at Japan’s National Institute of Advanced Industrial Science and Technology have developed a drone that can pollinate flowers. The device, purchased for around $100, was modified by attaching patches of horse hair to its body. This hair was coated in liquid gel to make it sticky, allowing pollen grains to cling to the drone during flight. Tests showed the drone could effectively pollinate lily flowers, mimicking the role of a bee.
The team envisions a future where robotic pollinators, guided by GPS and artificial intelligence, could autonomously follow predetermined paths to pollinate crops across fields. While the current prototype works with large flowers like lilies, experts note that scaling the technology for widespread agricultural use will require significant development. Katja Hogendoorn, a postdoctoral researcher at the University of Adelaide, described the work as an intriguing first step. If successful, drone pollinators might become an essential tool in sustaining plant reproduction as natural bee populations continue to decline.
