Try the example robot

Goal: exercise training, checkpoint export and inference using the included diffbot. You need Linux x86-64 and pixi.

1. Select the example

git clone https://github.com/nobleo/dwarl.git
cd dwarl
pixi run setup --example

Pixi installs the environment on first use. Setup selects the example robot; this path needs no robot repository or ROS build.

2. Run a small training check

pixi run train --preset smoke

Expect a tiny dataset, two training iterations and a completed checkpoint. The command prints the exact run-specific test command. You can also use:

pixi run test --case doorway --set test.max_cases=1

A smoke policy is deliberately untrained. Navigation failure (exit code 1) is expected; an infrastructure failure (exit code 2) needs investigation.

3. See what happened

pixi run dwarl report --open
pixi run dwarl next

The report includes individual trajectories and motion traces. On a headless machine, the command prints the local report path.

Next: integrate your robot, or train a navigation policy.
