This BionicBee Mimics the Flight Patterns and Behaviors of Actual Bees

Have you ever wondered how engineers can learn from nature to create innovative technology? The BionicBee is a fascinating example of this, developed by Festo’s Bionic Learning Network. This tiny, ultra-light flying robot mimics the flight patterns and behaviors of real bees, flying autonomously in a swarm.

Ultralight Design

The BionicBee is remarkably small and light. Weighing only about 34 grams, it measures 22 centimeters in length with a wingspan of 24 centimeters. The developers used a method called generative design, which allows the software to find the optimal structure using minimal material while maintaining stability. This design is crucial for the bee’s maneuverability and flight duration.

Function Integration

Despite its small size, the BionicBee houses several complex components. Inside the compact body are the beating wing mechanism, communication technology, and control components for wing beats and wing geometry adaptation.

It also includes a brushless motor, three servo motors, a battery, a gear unit, and various circuit boards. The coordination between these parts allows the bee to precisely adjust its wing beats for different maneuvers.

Natural Flight Maneuvers

The BionicBee can perform intricate flight maneuvers with four degrees of freedom: pitch, roll, yaw, and lift. It flies with a stroke frequency of 15 to 20 hertz, and its wings beat back and forth at a 180-degree angle.

The geometry of the wings can be adjusted to generate more lift in different positions, enabling forward, sideways, and rotational movements.

Autonomous Swarm Flight

An indoor localization system using ultra-wideband (UWB) technology enables the BionicBee to fly autonomously in a swarm. The room contains eight UWB anchors, allowing the bees to measure their distances from these anchors and calculate their positions.

They follow paths specified by a central computer, ensuring safe and collision-free flight. Each bee is built by hand, and even slight differences can affect their flight. To handle this, the bees have an automatic calibration function, optimizing their controller parameters for seamless swarm coordination.

Conclusion

The BionicBee showcases how advanced technology can draw inspiration from nature. It joins a series of bionic flying objects developed by Festo’s Bionic Learning Network over the past 15 years. This innovative project not only advances our understanding of autonomous flight but also opens up new possibilities for future technological applications.
