• No-Coding Game Design: Developed the Unity game environment without traditional coding, ensuring accessibility and ease of use.

Story:

In creating "Rose: an AI Assistant Adapter, " I embarked on a journey to merge gaming technology with artificial intelligence. First, I developed an engaging Unity game environment where I integrated the API to breathe life into the character of Rose. Next, leveraging the Raspberry Pi 4 as an IoT and embedded system hub, I connected a push button to automate the launch of the Unity game upon startup. The Raspberry Pi 4 served as the central processing unit, managing data flow and interactions with Rose seamlessly. To facilitate robust communication, I integrated a Bluetooth speaker via USB, which acted both as a microphone for user commands and a speaker for Rose's responses. As a final touch, I incorporated two LED indicators on Rose's head, offering visual feedback on power status and operational readiness. This project not only transforms any Bluetooth speaker into a versatile AI assistant but also showcases the potential of Raspberry Pi in IoT and embedded systems, enhancing user interaction through immersive gaming dynamics and intelligent conversational capabilities.
