Researchers at Chiba University are developing advanced quadcopters that are capable of flying in formation using sophisticated image processing and motion capture technologies. Each of these mini quadcopters weighs in at 300g and they are capable of carrying a total payload of 500g, which includes a 250g battery pack. This innovative approach to drone technology could revolutionize various fields, from search and rescue missions to environmental monitoring.
The researchers are currently using four quadcopters together, but they have ambitious plans to use more at once. Increasing the number of quadcopters in formation would enable them to gather information faster and more efficiently. This scalability is crucial for applications that require rapid data collection over large areas, such as disaster response or agricultural monitoring.
Advanced Image Processing and Motion Capture
The quadcopters rely on a network of cameras that capture markers placed on each drone. These images are then sent to a host computer, which calculates the position and attitude of each quadcopter with remarkable precision. According to the researchers, positioning can be done to within 1 mm. This high level of accuracy is essential for maintaining formation and preventing collisions.
The control frequency of the system is 100 Hz, meaning that the position and attitude of each quadcopter are calculated every 10 milliseconds. This rapid processing ensures that the quadcopters can make real-time adjustments to their flight paths, maintaining formation even in dynamic environments.

Potential Applications and Future Developments
The potential applications for these quadcopters are vast. In search and rescue operations, a fleet of drones could quickly scan large areas for survivors, providing real-time data to rescue teams. In agriculture, these quadcopters could monitor crop health, identify pest infestations, and even assist in precision farming by delivering targeted treatments.
Environmental monitoring is another promising application. A formation of quadcopters could be used to track wildlife, monitor deforestation, or measure air and water quality. The ability to deploy multiple drones simultaneously would allow for comprehensive data collection over large and potentially inaccessible areas.
The researchers at Chiba University are also exploring ways to enhance the capabilities of these quadcopters. Future developments may include integrating advanced sensors, such as thermal cameras or LiDAR, to expand the range of data that can be collected. Additionally, improvements in battery technology could extend the flight time of these drones, making them even more versatile.
