Android + ROS 2: Building a Robot Control App with Kotlin

Physical AI systems integrate Android, NVIDIA Jetson, and ROS 2 to separate user interfaces, edge AI compute, and robotics middleware. Android applications developed in Kotlin provide operator interfaces for telemetry, camera streams, and movement commands. Advanced architectures incorporate LLMs for voice-controlled natural-language interfaces, converting speech into structured robot actions via a safety validator. This modular approach allows individual component upgrades, utilizing ROS 2 to coordinate workloads between the Android gateway and robot hardware for efficient control.
