Dopamiini: Real-Time Interaction to Combating Loneliness with Smart Wheelchair Integrated Chatbot Support Model

The “Dopamiini” wheelchair, which integrates four control systems and a personalized AI chatbot to help older people overcome their obstacles and loneliness, was developed in this paper. This prototype was constructed using the GPT-3 API for chatbot functionality and the Python library pyttsx3 for offline text-to-speech conversion. When it comes to obstacle recognition, our proposed wheelchair shows an error of no more than ± 0.4 cm up to a distance of 400 cm. It takes an average of 5.6 seconds to reach the maximum speed. In order to monitor and regulate its performance in real time, this is equipped with a dashboard and a GPS navigation system. To make the prototype portable and effective, its weight is close to 2.7 kg.
