Robot software updates tested before deployment
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.

Why Fraeno exists
A green build can still leave a robot standing still.
Robot software depends on packages, drivers, containers, launch files, and operating system libraries working together. A small update can compile cleanly and still stop messages, sensors, or commands at runtime.
How it works
Fraeno tests the old system against the new one.
Every update becomes a controlled comparison before it can reach the robot.
Current system
Healthy
Controller
receiving data
Sensor
20.6 Hz
Commands
20.6 Hz
The trusted version runs first and records the behavior that matters.
Updated system

The new version builds, but the live comparison catches the broken message flow.
-
01
Fraeno finds an update
It opens a focused pull request with one reversible change.
-
02
Both robot systems run
The trusted version and the update start in clean, isolated environments.
-
03
Real behavior is compared
Fraeno checks the nodes, messages, services, diagnostics, and rates you declare.
-
04
The pull request gets a clear answer
The update passes or stops with the exact behavior that changed.
A real failure caught
The code built. The robot stopped communicating.
A ROS 2 update changed how a sensor sent messages. The controller still expected the old delivery behavior, so it received nothing. The command output dropped from 20.6 Hz to 0 Hz.
Fraeno saw the running system change and blocked the pull request.

Fraeno decision
Do not merge
Ready now
Narrow enough to trust. Useful enough to run today.
Fraeno is working first for ROS 2 Humble projects on Ubuntu 22.04 and amd64. The production GitHub App has passed a safe update, blocked a communication regression, and completed a fresh external repository test.
- What it watches
- Nodes, topics, services, actions, transforms, diagnostics, and message rates
- Where it reports
- On the pull request your team already reviews
- What comes next
- 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.

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