Vision

Our team applies deep expertise in motor control, embedded systems, and autonomous navigation to rethink drone architecture from first principles.

Open-source flight control software has reached a high level of maturity. Solutions such as BetaFlight, iNAV, ArduPilot, and PX4 serve the community well. Yet critical questions remain:

  • Platform Flexibility — Can flight controllers be more adaptable across diverse deployment scenarios?
  • Architectural Innovation — What alternative design paradigms lie between lightweight controllers like BetaFlight and full-featured systems like PX4?
  • Converged Architecture — Can we leverage the mature Raspberry Pi ecosystem to unify low-level PID control with high-level processing—computer vision, autonomous mission planning, and real-time decision-making—on a single, cohesive platform?

We are building toward that convergence.

Technology Stack

Low-Level Processing

  • RP2350 — Dual-core MCU for PID loops, motor control, and IMU feedback
  • Modular design — Add more RP2350 chips as I/O requirements grow

High-Level Processing

  • Raspberry Pi — From Zero 2 W to Pi 5 (CM5)
  • Vision processing, mission planning, ground station communication, and autonomous contingency handling

Software Foundation

  • Rebuilt from first principles: PID loops, motor control, IMU feedback
  • High-level sensor fusion: optical flow, GPS, LIDAR
  • MAVLink proxy for integration with ground station and mission planning tools
