The term digital twin in robotics is one of the most overused — and misunderstood — concepts in modern engineering. Digital twins are used to create dynamic digital replicas of physical products and their physical counterparts, not just in robotics but also in construction, manufacturing, and other industries.

Artificial intelligence in robotics is often associated with large language models, vision systems, or reinforcement learning. But one of the most transformative concepts emerging in modern AI — especially for robots and cyber-physical systems (CPS) — is the world model.

Containers Are Tools, Not Religion in Cyber Physical Systems

Containerization has become almost ideological in modern software engineering. In web infrastructure, “just Dockerize it” is often the correct answer. In robotics, that mindset can either save you months of pain — or create subtle, catastrophic problems that only appear under load, in the field, or during a live demo.

Artificial intelligence (AI) has rapidly evolved from a field focused on abstract problem-solving and digital environments to one that increasingly shapes our interactions with the physical world. At its core, AI refers to the development of intelligent systems capable of analyzing data, learning from experience, and making decisions—often with minimal human intervention. Traditional AI systems excelled in software domains, such as natural language processing, computer vision, and data analytics, operating primarily within virtual environments.

Scope of this article (important)
This article covers only the Docker container setup: persistence, audio, GPIO, Whisper server access, and Isaac ROS integration on JetPack 6.x.
LLMs, VLMs, dialog logic, and intelligence layers (VAD → Whisper → LLM → TTS) will be covered in future articles.

Think of this as building the body and nervous system of your Jarvis-like runtime — not the brain yet.

A deliberately long, deeply technical, experience‑driven guide. Written both for my future self (who will have forgotten all the painful details) and for readers who want to install and actually understand ROS 2 + Isaac ROS on Jetson Orin Nano Super — without wasting weeks on unclear or misleading documentation.

A practical, low-level guide from theory to production on Jetson

Text-to-Speech (TTS) looks simple on paper: you provide text, you get audio.

In practice, especially on embedded hardware, inside containers, and integrated into a ROS 2 system, achieving low latency, stable audio, and reproducible behavior is surprisingly difficult.

If you’ve ever watched a robot arm pick up a part, a drone gimbal stabilize a camera, or a humanoid place its foot precisely on the ground, you’ve seen kinematics in action. Kinematics is the branch of mechanics that describes motion without talking about forces.

This article is written for anyone who wants a beginner-friendly but technically correct explanation of UART, plus a practical, step-by-step tutorial on Jetson Orin Nano (JetPack 6.x) using:
