DESIGN & DEVELOPMENT OF A MODULAR AUTOMATED PET FEEDER

ABSTRACT: The increasing demand for smart pet care solutions has led to the development of automated feeding systems capable of improving convenience and animal welfare. This paper presents the design, development, and prototyping of a modular automated pet feeder integrating an Arduino-based food dispensing mechanism and a gravity-fed water dispenser. The product was designed using CAD tools and validated through Fused Deposition Modeling (FDM) additive manufacturing. A modular architecture was adopted to simplify assembly, maintenance, and future upgrades. Multiple design iterations were evaluated to optimize assembly tolerances and improve functionality. The results demonstrate the feasibility of combining additive manufacturing and embedded electronics for the rapid development of smart pet care products
