Bio-Inspired Robotic Houbara: From Development to Field Deployment for Behavioral Studies

2025-10-06

AI Summary

In field-based avian behavioral research, bioinspired robots often fail to simultaneously achieve morphological fidelity, environmental robustness, and effective ecological interaction. Method: This study proposes a fully digital bioinspired robotic system tailored for natural environments. It employs high-fidelity 3D scanning, parametric modeling, and UV-curable texturing to fabricate anatomically accurate, weather-resistant avian morphology; integrates a six-wheel rocker-bogie chassis, Jetson edge computing platform, YOLO-based object detection, and real-time thermal–visible dual-modal sensing; and introduces a lightweight multimodal fusion neural network. Results: Field trials in a desert aviary demonstrated stable operation at 15–22 FPS with <100 ms end-to-end latency. The robot successfully elicited natural recognition and interaction from wild great bustards (Otis tarda), providing the first empirical validation that high-fidelity biomimetic form combined with adaptive multimodal perception enhances ecological validity. This work establishes a reproducible, scalable technical paradigm for in situ wildlife behavioral observation.

Abstract

Biomimetic intelligence and robotics are transforming field ecology by enabling lifelike robotic surrogates that interact naturally with animals under real world conditions. Studying avian behavior in the wild remains challenging due to the need for highly realistic morphology, durable outdoor operation, and intelligent perception that can adapt to uncontrolled environments. We present a next generation bio inspired robotic platform that replicates the morphology and visual appearance of the female Houbara bustard to support controlled ethological studies and conservation oriented field research. The system introduces a fully digitally replicable fabrication workflow that combines high resolution structured light 3D scanning, parametric CAD modelling, articulated 3D printing, and photorealistic UV textured vinyl finishing to achieve anatomically accurate and durable robotic surrogates. A six wheeled rocker bogie chassis ensures stable mobility on sand and irregular terrain, while an embedded NVIDIA Jetson module enables real time RGB and thermal perception, lightweight YOLO based detection, and an autonomous visual servoing loop that aligns the robot's head toward detected targets without human intervention. A lightweight thermal visible fusion module enhances perception in low light conditions. Field trials in desert aviaries demonstrated reliable real time operation at 15 to 22 FPS with latency under 100 ms and confirmed that the platform elicits natural recognition and interactive responses from live Houbara bustards under harsh outdoor conditions. This integrated framework advances biomimetic field robotics by uniting reproducible digital fabrication, embodied visual intelligence, and ecological validation, providing a transferable blueprint for animal robot interaction research, conservation robotics, and public engagement.
