NutriPepper: Building a Robot That Cannot Lie

A developer series documenting the end-to-end build of NutriPepper; a RAG-powered nutrition education system deployed on the Pepper humanoid robot at JKUAT. Seven articles covering the real engineering decisions, honest evaluation results, and lessons learned from building an AI system that grounds every response in verified WHO, FAO, and Kenya Ministry of Health guidelines. Because in health education, a confident wrong answer isn't just unhelpful, it's dangerous.
