New Free Tool Builds Robot Software for Raspberry Pi in Minutes, Not Hours

Most small robots — the kind hobbyists, students and startups build — run on tiny, cheap computers like the Raspberry Pi or the Kria. The software that makes them move, see and decide is called ROS 2 (basically the operating system for robots). The annoying part: to get that software onto a small board, you usually have to build it on the board itself, and that can chew up hours of waiting. Some boards are so poorly supported that the official pre-made packages simply don't exist.

Enter colcon-buildx. Think of it like cooking a big meal in a professional kitchen instead of your cramped apartment: you do the heavy work on a powerful machine, then deliver the finished dish to the tiny board. The tool builds everything inside a ready-made software container (a sealed box that has the right ingredients), so what you build matches exactly what the board expects. When it's done, a single command copies the result over.

It comes with prebuilt packages for several popular boards: the Kria K26, the Pynq-Z1 and Pynq-Z2, and Raspberry Pi models running Debian 12 or 13, in both 64-bit and 32-bit versions. For boards where nothing official existed before, the project also publishes installable bundles you can drop in directly. That matters most for the older 32-bit boards, which the official robot software community had essentially stopped supporting.

Nobody should be surprised by rough edges. The author is upfront: the older 32-bit versions are slow to build from scratch, the included package list is opinionated (a lean set without graphics extras), and one advanced feature is still experimental. This is a community project, not an official release, and the developer is openly asking for bug reports and requests to add more boards. For anyone who has ever stared at a tiny computer compiling for three hours, that's a welcome trade.
