Multi-Spectral Sensor Fusion in Throwable Reconnaissance Device for Real-Time Situational Awareness
Maixduino Kit for AI+IoT

This idea proposal outlines the design for a throwable reconnaissance device intended for rapid deployment in combat scenarios, conceived as part of a hackathon challenge. The proposed core of the device is a 3D-printed geodesic sphere housing a Seed Maxduino Kit with its built-in ESP32 processor as the central embedded system.
The device is designed to autonomously unfold into a low-profile sensory platform upon deployment. We propose integrating the following sensors:
1. OmniVision OV5647 sensor for visible spectrum imaging
2. AMS TMD3725 for UV light detection
3. VL53L1X Time-of-Flight sensor for proximity and basic depth mapping
These sensors would provide a 270-degree field of view, offering multi-spectral data capture of the immediate environment. Power supply is planned through an array of Powerfilm MP3-37 flexible thin-film solar cells integrated into the unfolded structure.
For communication, we propose a LORA-based Mobile Ad Hoc Network (MANET) using the RFM95W transceiver module. This would allow the device to form a mesh network with other deployed units, enabling data transmission in environments where traditional communication systems may be unreliable.
To prevent technology compromise, we suggest incorporating a self-preservation feature utilizing a small thermite charge. Upon detecting potential capture through its accelerometer and gyroscope (MPU-6050), it would initiate a data wipe followed by physical destruction.
If developed, this device could provide rapid situational awareness in combat scenarios. The project aims to demonstrate the potential of integrating commercially available sensors and communication modules into a compact, deployable form factor.
This proposal contributes to the field of tactical reconnaissance by suggesting a practical implementation of sensor fusion and autonomous deployment in a compact form factor. If realized, such a device could inform future developments in rapid-deployment sensory systems for military applications.
