Created Roboista, a witty barista robot who serves coffee with a dash of humor and personality. Roboista uses computer vision to identify customers, machine learning to remember their coffee preferences, and natural language processing to engage in cheerful banter. Built on a Jetson Nano platform, Roboista combines TensorFlow Lite for real-time customer interaction and Arduino-driven robotics for precise brewing operations. The robot didn’t just improve the cafe’s efficiency—it became a beloved community figure, boosting both sales and smiles.
