Multi-Purpose Amphibious UGV.
Raman Singh
This electronic document details the design methodology and fabrication process for a small-scale Unmanned Ground Vehicle (UGV) engineered for high resilience and robust remote operation in challenging, potentially amphibious environments. The platform integrates the Ai-Thinker ESP32-CAM System-on-Chip (SoC) to provide real-time, high-resolution visual feedback and Wi-Fi based remote control. Actuation is achieved using high-torque MG996R servo motors and L293D-controlled drive motors, managed using the Arduino environment. Crucially, the chassis utilizes Additive Manufacturing (AM), focusing on a water-resistant hull design and flexible wheels printed in Thermoplastic Polyurethane (TPU 95A). The material analysis shows the TPU offers exceptional elongation (>560%) and good chemical resistance, key factors for amphibious endurance and operational durability.
