| # Atech SimReady modules and boards | |
| 3-D simulation assets for the Atech boards and modules on [atech.dev](https://atech.dev): | |
| every module in the [Atech SDK](https://pypi.org/project/atech/) catalog, the products | |
| the SDK has no firmware for yet (USB-C, Power Jack, Micro-SD Card, Big Screen, Camera, | |
| Soil Sensor, Load Cell), and the 8-, 10- and 14-port boards. | |
| ## Build with the real hardware | |
| - **Firmware and drivers: the `atech` Python library.** `pip install atech` gives you | |
| the module catalog, Atech's module drivers, and the commands that turn a small | |
| `project.yaml` into firmware, build it, flash the board and talk to it from your | |
| laptop (`atech new`, `atech build`, `atech upload`, `atech monitor`). It can also | |
| run that firmware on an emulated board (`atech emulate`) and export these assets | |
| (`atech sim-assets`). Source: [github.com/atechdotdev/python-sdk](https://github.com/atechdotdev/python-sdk). | |
| - **Building on the Atech platform: [atech.dev](https://atech.dev).** The boards and | |
| modules these assets model, and the platform to build projects with them. | |
| ## Layout | |
| Each top-level folder is one SimReady asset package, in three formats: | |
| ``` | |
| atech_<asset>/ | |
| ├── com.nvidia.simready.packaging.json package marker (license, BOM hash) | |
| ├── .metadata/ root USD list, bill of materials (sha256 per file) | |
| ├── simready_usd/<asset>.usd USD (crate), following NVIDIA SimReady: Isaac Sim / Omniverse | |
| │ └── .thumbs/256x256/<asset>.usd{,_light,_transparent}.png | |
| ├── mjcf/<asset>.xml + mjcf/meshes/<asset>/*.stl MuJoCo | |
| └── urdf/<asset>.urdf + urdf/meshes/<asset>/*.stl ROS / Gazebo | |
| ``` | |
| Asset names are `atech_<module id>` (e.g. `atech_distance_sensor`) and | |
| `atech_board_<board id>` (e.g. `atech_board_14port`); the robot-arm module is | |
| `atech_robot_arm_integrator`, its product name. | |
| Generated with `atech sim-assets --all --board 8port,10port,14port` | |
| (`pip install "atech[sim]"`) on the SDK's development version, then repackaged one | |
| folder per asset. The thumbnails | |
| are MuJoCo renders of the MJCF, so they show the CAD's flat material colours, not | |
| the USD's PBR shading or the display's screen texture. | |
| ## What is real and what is not | |
| - **Visuals** are Atech's production CAD (module-renders release v1.7), with the | |
| GLB's own PBR materials. **Colliders are boxes**: the bounds of that CAD. | |
| - **The 8-port board** is Atech's CAD of it ("Node 8 Position Motherboard", from | |
| Atech's website models), not yet in the module-renders release; its source says so. | |
| - **Derived models.** The PIR, CO₂ (SCD40), robot-arm, stepper, power-jack, soil-sensor | |
| and load-cell modules have no model in the CAD release. Theirs are built from the CAD that | |
| exists plus placeholder parts, and say `derived:` in every format | |
| (`atech:visual:source` in USD, the MJCF text, the URDF comment). They are not Atech CAD. | |
| The CO₂, robot-arm, power-jack, soil-sensor and load-cell modules follow Atech's | |
| product renders; the PIR is drawn as its | |
| AM312 sensor. The Robot Arm Integrator (`atech_robot_arm_integrator`, catalog id `robot_arm`) plugs into one port, but its housing is two cells | |
| long: its `connector` frame is the centre of the -x cell. | |
| - **Masses and inertias are placeholders.** Atech has not published them. | |
| - With real CAD, NVIDIA's SimReady validator reports VG.007 warnings: the CAD | |
| tessellation has non-manifold vertices. | |
| `atech guide sim` (in the SDK) documents every attribute and the full layout. | |
