Researchers from TU Delft have developed an insect-inspired navigation strategy that allows tiny, lightweight robots to autonomously navigate long distances with minimal computation and memory.
Key insights from insect navigation: The researchers drew inspiration from how insects like ants visually recognize their environment and combine it with step counting (odometry) to find their way back home:
Enabling autonomous navigation in tiny robots: The insect-inspired approach addresses the challenges of making tiny, resource-constrained robots navigate autonomously without relying on external infrastructure:
Potential real-world applications: While not as full-featured as state-of-the-art navigation, the insect-inspired strategy could enable tiny robots to take on valuable real-world tasks:
Looking ahead: The researchers see their work as an important step towards practically deploying tiny autonomous robots in real-world scenarios where full mapping and navigation capabilities are not always required. By taking inspiration from nature, they were able to develop an efficient, minimal navigation strategy well-suited to the extreme size, weight, and power constraints of micro-robots. With further development, this approach could open the door to novel uses of swarms of tiny autonomous drones for sensing, monitoring, and search tasks in complex environments.
