# RoboLens > The Inspect AI for robotics — an evaluation framework for physical AI and VLA (vision-language-action) models. RoboLens is the open-source evaluation framework for physical AI and VLA (vision-language-action) models — the "Inspect AI for robotics". A benchmark is a Task (dataset of Scenes + scorers) run against two swappable inputs: a Policy (the VLA) and an Embodiment (a real robot or simulator). ## Guide - [Home](https://robocurve.github.io/robolens/index.md) - [Quickstart](https://robocurve.github.io/robolens/guide/quickstart/index.md) - [Concepts](https://robocurve.github.io/robolens/guide/concepts/index.md) - [Writing a benchmark](https://robocurve.github.io/robolens/guide/writing-a-benchmark/index.md) - [Policies and embodiments](https://robocurve.github.io/robolens/guide/policies-and-embodiments/index.md) - [Scoring](https://robocurve.github.io/robolens/guide/scoring/index.md) - [Logging & Rerun](https://robocurve.github.io/robolens/guide/logging-and-rerun/index.md) - [Plugins & the registry](https://robocurve.github.io/robolens/guide/plugins/index.md) - [Command-line interface](https://robocurve.github.io/robolens/guide/cli/index.md)
