Motivation

The motivation for developing a customized protein vending machine arises from the everyday challenges faced by fitness enthusiasts. While supplements such as protein powders, BCAAs, and pre-workouts are essential for muscle growth and recovery, they are often inconvenient to prepare, carry, and tailor to individual needs. Existing solutions, including ready-to-drink products or conventional vending machines, fail to provide true personalization, remain costly, and generate environmental concerns through single-use packaging. At the same time, gym-goers increasingly demand convenience, efficiency, and health-focused options that integrate seamlessly into their routines. Therefore, this work seeks to deliver an in-gym, automated dispensing system that provides personalized nutrition on demand—reducing preparation burdens, enhancing accessibility, and creating a foundation for broader smart healthcare applications.
