📈 Executive Summary

In a major milestone for autonomous micro-robotics and closed-loop edge-processing, Tornyol Systems (co-founded by Alex Toussaint) has demonstrated the first successful air-to-air live target intercept (flying moth) using a custom 40-gram autonomous micro-drone.

This project, which initially debuted as a DIY proof-of-concept at Hackaday Supercon 2024 ("How to Detect (and Kill) Mosquitoes With Off-the-Shelf Electronics"), has been heavily refined and miniaturized into a commercial-grade, highly precise biological-threat interception system.

By utilizing off-the-shelf car parking sensors, phased-array acoustic radar, and localized FPGA-driven signal processing, Tornyol Systems has created an incredibly low-cost, high-frequency, and fully sovereign pest-eradication platform.

🏗️ Hardware Architecture & Sensor Fusion

The Tornyol System consists of two primary hardware nodes operating in a closed, high-speed telemetry loop:

1. The Micro-Drone Interceptor

• Form Factor & Weight: Extremely lightweight, weighing only 40 grams (1.4 ounces). This minimises kinetic risk, battery consumption, and safety hazards in domestic environments.
• Guidance System: Leverages cheap, highly available, off-the-shelf ultrasonic car park assist sensors combined with localized digital signal processing (DSP).
• Operating Range: Capable of seeking, locking, and neutralizing flying insect targets at up to 8 meters (~26 feet) away from the base station.

2. The LeSonar2 Phased-Array Sonar Base Station

Because a 40g drone has zero payload capacity for heavy on-board camera sensors, GPUS, or bulky radar, the spatial mapping and target-tracking are offloaded to a high-density acoustic base station:

• Microphone Array: Built with a phased-array of 380 commodity smartphone microphones.
• Acoustic Processing: Driven by a low-cost, high-speed Artix-7 FPGA which reconstructs the room in high-fidelity 3D acoustic space.
• Sub-Millimeter Resolution: Capable of measuring movements down to 0.1 mm in real-time.
• Signature Filtering: The base station identifies target mosquitoes specifically by filtering for their unique, high-frequency wingbeat signature (preventing false-positives on harmless insects or dust particles).
• Control Loop: Flight commands are calculated and transmitted to the drone in real-time. The system is currently driven by a local PC, but is migrating to fully embedded edge-hardware in the coming weeks, eliminating PC dependency.

💼 B2B & STEM Consulting Opportunities (Sentinel Integrations)

This project has enormous strategic value, particularly for our STEM/Robotics volunteering programs and corporate-sponsored academic consulting plays:

Playbook A: STEM Robotics Volunteering & Academic Outreach

• The Play: Michael's goal is to volunteer for university/college STEM robotics programs as a B2B consulting play targeting university researchers and program sponsors.
• The Execution:

* Use the Tornyol System as a benchmark masterclass curriculum. It perfectly demonstrates how high-end military concepts (phased-array radar, closed-loop telemetry, sensor fusion) can be built using cheap, commodity consumer electronics (smartphone mics, car park sensors, low-end FPGAs).

* Deliver workshops to college robotics groups on "Low-Cost Phased Array Sonar and Embedded DSP." This immediately builds Sentinel’s high-value authority among university research heads and corporate program sponsors.

Playbook B: Edge DSP & FPGA Pipeline Consulting

• The Play: Organizations struggle to deploy low-latency, real-time spatial processing because they rely on bulky, power-hungry GPU architectures.
• The Execution:

* Help clients refactor high-frequency, low-latency processing pipelines from Python/PyTorch onto low-cost Artix-7 FPGAs or microcontroller units (MCUs) using C/Verilog.

* Deliver massive cost, size, and weight reductions for industrial IoT, robotics, and environmental monitoring devices.

Playbook C: Agricultural & Environmental Pest Management

• The Play: Greenhouses, commercial organic farms, and research laboratories require highly targeted, chemical-free pest control to protect high-value crops.
• The Execution:

* Design and deploy custom-scoped "Acoustic Shield Zones" using scaled-down phased-array smartphone microphone detectors.

* Integrate automated alerts or coordinate with micro-interceptor fleets to eliminate targeted pests autonomously before they damage crops, keeping full compliance with organic regulatory frameworks.
