I’ve been learning ROS, but I don’t have a robot at hand. My idea: use the iPad I already have as a ROS node and receive data on my Mac — sensor data like IMU, Camera, Battery, etc. — to understand how ROS nodes collect and publish data.

In this article, we’ll:

Set up the MacBook as a ROS node (using Docker)
Turn the iPad into a ROS node (using Conduit)
Receive the iPad’s sensor data on the MacBook

The ROS documentation mentions installing ROS2 natively on macOS, but in practice this runs into many deprecated packages and version dependency issues. After a few rounds of debugging with Claude Code, I decided to skip native installation — my goal at this stage was to see the data format ROS2 produces, not fight with the toolchain.
