Fraeno

Built first for ROS 2 Humble

Update robot software without breaking the robot.

Fraeno automatically manages and updates robot software dependencies, and tests the complete robotic system before changes are deployed.

essentially, dependabot for robots + integration testing.

The code built successfully. Fraeno still blocked the change because the running robot system stopped communicating.

Why Fraeno exists

A green build does not mean the robot still works.

Robot software crosses ROS packages, operating system libraries, containers, hardware drivers, and launch files. A small update in one layer can quietly change the whole system.

How it works

One update becomes one controlled test.

  1. 1

    Fraeno finds a dependency update

    It opens a focused pull request so the change is easy to review and reverse.

  2. 2

    The old and new systems both run

    Your trusted test plan starts each version in a clean environment.

  3. 3

    Fraeno compares real behavior

    It checks the interfaces and signals that matter to the robot.

  4. 4

    The change passes or stops

    The pull request shows what changed and why Fraeno accepted or blocked it.

A real failure caught

The build passed. The robot stopped communicating.

A test update changed how a ROS 2 sensor published messages. The controller still required reliable delivery, so it received nothing. The command topic fell silent and diagnostics worsened.

Fraeno saw the running system change and blocked the pull request.

Before the update Healthy

After the update Blocked

Ready now

A working vertical prototype with a narrow first target.

Fraeno has already run a complete check through its production GitHub App. A safe update passed. A buildable ROS 2 communication regression was blocked.

First target
ROS 2 Humble on Ubuntu 22.04 and amd64
Current proof
A separate ROS 2 repository using the production GitHub App
Next proof
A design partner running Fraeno on a real robot repository

A passing result means the configured target and declared probes passed. It does not claim that every possible robot behavior is safe.

Fraeno is opening its first pilot

We will help turn that failure risk into a repeatable integration test.
