Bitcraze Plans Live Autonomous Nano-Drone Swarm Demo at ERF 2026

Bitcraze is bringing a live swarm to the European Robotics Forum. The Swedish drone tech company will demonstrate multiple Crazyflie nano-drones flying autonomously in a controlled environment at booth #90 when ERF 2026 opens in Stuttgart from March 23-27, a public showcase of the kind of indoor testbed infrastructure that has quietly become foundational to autonomous flight research.

Fredrik Ehrenstråle laid out the plan in a February 23 blog post, writing that the demonstration "features multiple nano-drones flying autonomously in a controlled environment and reflects how the platform is used in research and applied robotics development." The Crazyflie platform will handle all flight autonomously, with no pilot input, making the demo a direct illustration of the scalable indoor testbed concept Bitcraze has championed across both academic and industrial R&D settings.

The company has also signaled that multi-drone choreography will be part of the ERF program, along with broader discussion of scalable indoor testbed design. Ehrenstråle framed the exercise as something larger than spectacle: "The purpose of the demonstration is not the flight itself, but the role such setups play in validating aerial robotics concepts."

That distinction matters for the drone community. Indoor, small-scale autonomous systems give researchers and engineers a way to stress-test autonomy, perception, control algorithms, and multi-robot coordination under repeatable conditions before committing resources to outdoor flights or larger platforms. As Ehrenstråle put it, the controlled setting makes it possible to "explore system behavior, test assumptions, and iterate rapidly before moving to larger platforms or less controlled environments." For FPV builders and racing teams increasingly experimenting with autonomous modes, that iterative validation loop is the same logic that separates a reliable flight controller tune from one that fails under pressure.

The Crazyflie platform carries significant research credentials into the ERF booth. Bitcraze says the platform has been referenced in hundreds of peer-reviewed papers worldwide, with academic applications spanning swarm robotics, learning-based control, and human-robot interaction. On the industrial side, similar indoor testbed setups are being used to de-risk development pipelines, validating ideas at small scale before the cost and complexity of outdoor or large-drone operations enter the picture.

Booth #90 will also be a venue for hands-on technical discussions, according to the blog post, though Bitcraze has not published a detailed demo schedule or named the engineers who will be staffing the exhibit. With ERF 2026 still two weeks out, the live flight setup represents the most visible public test yet of how the Crazyflie ecosystem performs as a swarm demonstration platform in front of a professional robotics audience.
