Voices From the Community

"It quickly turned out that the Crazyflies, with their small size, open-source firmware, ROS compatibility, and, as we happily found out after hours upon hours of crashes, amazing durability, would be the perfect platform to test our controllers."

Dimitrios Chaikalis, New York University

"Crazyflies (and other drones in this weight class) are extremely fun to fly and prototype with!"

Suryansh Sharma, TU Delft

"With those [Crazyflies] we had many possibilities to learn about electrical engineering – from sensors, microcontrollers, timers, and motors to LEDs, batteries, embedded systems, FreeRTOS tasks, state estimation, and controller – and all this with a high fun potential and a low risk of accidents, as with their weight of only 30g they hardly ever do any damage."

Hanna Müller, ETH Zürich

"Drones like the Crazyflie are ideal for such tasks, since they are small enough to navigate in narrow spaces, safe, agile, and very inexpensive."

Bart Duisterhof & Prof. Guido de Croon, TU Delft MAVLab

"When it came time for hardware experiments, using the Crazyflie just made sense. A tiny solver deserves a tiny robot."

Sam Schoedel & Khai Nguyen, Carnegie Mellon University / TinyMPC
