EmbodiedSWE studies how frontier coding agents can help robotics. It has four parts:
- **EmbodiedSWE-Bench**, an agent-native benchmark of long-horizon, dexterous everyday tasks, built on Isaac Lab.
- **Evaluation** of frontier coding agents on these tasks: task performance, completion time, and inference cost.
- **EmbodiedSWE-Gen**, which diversifies one verified agent solution into a large trajectory dataset for training general robot policies.
- **Agent improvement**, which generates new tasks from existing ones and improves the coding agent with RL on verified outcomes.
See the [paper](https://arxiv.org/abs/2609.27308) for the full benchmark, evaluation, and data-generation details.
> **Note:** this repository is under active development. Folder layouts, interfaces, and settings
> may change as the codebase evolves.
## Installation
Requirements: Linux, an NVIDIA GPU with a CUDA 12.x driver, and [`uv`](https://docs.astral.sh/uv/).
```bash
git clone <this repo> && cd <this repo>
./scripts/bootstrap_isaaclab_5_1.sh # Isaac Sim 5.1 + Isaac Lab 2.3.2 + robobench into ./.venv
source .venv/bin/activate
export OMNI_KIT_ACCEPT_EULA=YES # Isaac Sim asks interactively otherwise (hangs headless runs)
# Optional: prefetch every task and room (~3.4 GB); otherwise env.build() fetches what it needs.
python -m robobench.scripts.fetch_assets
uv pip install "pin==2.7.0" "pin-pink==3.1.0" "daqp==0.8.5" "numpy==1.26.0" # whole-body IK (pink_ik)
```
Task assets and shared rooms live in the Hugging Face dataset `EmbodiedSWE/robobench-assets`.
Building an environment automatically downloads its required asset groups and verifies their SHA-256
checksums against `robobench/assets_manifest.json`. Verified local copies are reused, including offline.
Listing tasks does not download anything. `fetch_assets --check` verifies the whole local collection.
Every built-in registered task configuration declares its default room in its suite's
`configs/envs.py`, including alternate robots and control modes. Shared loading code lives in
`robobench/core/rooms.py`; downloaded rooms live in the ignored `robobench/assets/rooms/` directory.
Use `--room none` with the smoke launcher or `cfg.build(room=None)` to disable scenery explicitly.
Set `COSIGEN_ASSET_DIR` before starting Python to use a writable cache outside the checkout.
See [task rooms and asset downloads](docs/rooms.md) for the room assignments and maintainer commands.
The `deformable` suite runs on the Newton physics backend and needs a separate venv; see
[`robobench/suites/deformable/README.md`](robobench/suites/deformable/README.md).
## Quick start
Preview a task:
```bash
python -m robobench.scripts.smoke --list # all registered tasks
python -m robobench.scripts.smoke --env assembly.bulb.franka.osc --livestream 2 # random actions, live view
```
Tasks are named `suite.scene[.robot[.control_mode]]`. The environment API and design are described
in [`robobench/README.md`](robobench/README.md).

## Solving a task
The easy way: open the repo in a coding agent such as Claude Code or Codex, point it at
`robobench/README.md`, and ask it to solve a task, e.g. `assembly.bulb.franka.osc`. A solution is a
Python program exposing `solve(env)`; the contract the agents see is
[`eval/prompts/_contract.md`](eval/prompts/_contract.md).
For rigorous, large-scale evaluation, `eval/` runs the agent in an isolated Docker container under a
time budget and grades its solutions afterwards in fresh containers on independently randomized episodes.
```bash
python eval/scripts/build_env.py --name bulb_e2e --stage bulb:franka # build the world once
python eval/scripts/run_agent.py experiments/bulb_e2e --agent claude # one agent run in Docker
python eval/scripts/run_grade.py experiments/bulb_e2e --run <run> # grade the delivery
```
Prompt conditions (hints, rules, blocked features) are authored yaml files in `eval/configs/` and
`eval/prompts/`. Docker images and the container contract are documented in
[`eval/docker/README.md`](eval/docker/README.md).
## Data engine
Once a task is solved, `data_engine/` turns that one verified solution into a large, diverse,
per-episode-verified demonstration dataset. Coding agents author the diversity at five independent
levels: scene, strategy, phase, dynamics, and visual.
A generic launcher then mass-produces batched episodes, the scene's grader stamps a verdict on each
one, and the verified episodes are rendered and baked into a LeRobot dataset for policy training.
```bash
python data_engine/scripts/init_gen.py experiments/bulb_e2e/runs/<run> # start a campaign from a solved run
python data_engine/scripts/diversify.py <gen_root> data_engine/configs/scene_default.yaml # agent session that adds diversity
python data_engine/scripts/generate.py --headless <gen_root> --scene scene_1 --num_envs 8 # generate + verify a batch
python data_engine/scripts/render.py --headless <gen_root> --batches <batch> # render episodes to video
.venv-lerobot/bin/python vla/convert/convert.py <gen_root> --repo-id <name> # bake a LeRobot dataset
```
Training and closed-loop evaluation of VLA policies live in [`vla/`](vla/README.md).
