This package provides a simulator for vision-based tactile sensors, such as [DIGIT](https://digit.ml).
It provides models for the integration with PyBullet, as well as a renderer of touch readings.

NOTE: the simulator is not meant to provide a physically accurate dynamics of the contacts (e.g., deformation, friction), but rather relies on existing physics engines.

**For updates and discussions please join the #TACTO channel at the [www.touch-sensing.org](https://www.touch-sensing.org/) community.**


## Installation

The preferred way of installation is through PyPi:

```bash
pip install tacto
```

Alternatively, you can manually clone the repository and install the package using:

```bash
git clone https://github.com/facebookresearch/tacto.git
cd tacto
pip install -e .
```

## Content
This package contain several components:
1) A renderer to simulate readings from vision-based tactile sensors.
2) An API to simulate vision-based tactile sensors in PyBullet.
3) Mesh models and configuration files for the [DIGIT](https://digit.ml) and Omnitact sensors.

## Usage

Additional packages ([torch](https://github.com/pytorch/pytorch), [gym](https://github.com/openai/gym), [pybulletX](https://github.com/facebookresearch/pybulletX)) are required to run the following examples.
You can install them by `pip install -r requirements/examples.txt`.

For a basic example on how to use TACTO in conjunction with PyBullet look at [TBD],

For an example of how to use just the renderer engine look at [examples/demo_render.py](examples/demo_render.py).

For advanced examples of how to use the simulator with PyBullet look at the [examples folder](examples).

* [examples/demo_pybullet_omnitact.py](examples/demo_pybullet_omnitact.py): rendering RGB and Depth readings with a [OmniTact](https://arxiv.org/pdf/2003.06965.pdf) sensor.

* [examples/demo_pybullet_grasp.py](examples/demo_grasp.py): mounted on parallel-jaw grippers and grasping objects with different configurations.

* [examples/demo_pybullet_rolling.py](examples/demo_rolling.py): rolling a marble with two DIGIT sensors.

* [examples/demo_pybullet_digit_shadow.py](examples/demo_pybullet_digit_shadow.py): enable shadow rendering.

NOTE: the renderer requires a screen. For rendering headless, use the "EGL" mode with GPU and CUDA driver or "OSMESA" with CPU. 
See [PyRender](https://pyrender.readthedocs.io/en/latest/install/index.html) for more details.

## Operating System
We recommend to conduct experiments on **Ubuntu**.

For **macOS**, there exists some visualization problem between pybullet.GUI and pyrender as we know of. Please let us know if it can be resolved, and we will share the information at the repo!
