# differentiable robot model
[](https://circleci.com/gh/facebookresearch/differentiable-robot-model/tree/main)
[](https://github.com/psf/black)
Differentiable and learnable robot model. Our differentiable robot model implements computations such as
forward kinematics and inverse dynamics, in a fully differentiable way. We also allow to specify
parameters (kinematics or dynamics parameters), which can then be identified from data (see examples folder).
Currently, our code should work with any kinematic trees. This package comes with wrappers specifically for:
* TriFinger Edu
* Kuka iiwa
* Franka Panda
* Allegro Hand
* Fetch Arm
* a 2-link toy robot
You can find the documentation here: [Differentiable-Robot-Model Documentation](https://fmeier.github.io/differentiable-robot-model-docs/)
## Installation
Requirements: python>= 3.7
clone this repo and install from source:
```
git clone git@github.com:facebookresearch/differentiable-robot-model.git
cd differentiable-robot-model
python setup.py develop
```
## Examples
2 examples scripts show the learning of kinematics parameters
```
python examples/learn_kinematics_of_iiwa.py
```
and the learning of dynamics parameters
```
python examples/learn_dynamics_of_iiwa.py
```
## L4DC paper and experiments
the notebook `experiments/l4dc-sim-experiments` shows a set of experiments that are similar to what we presented
in our L4DC paper

}
```
## Testing
running `pytest` in the top-level folder will run our differentiable robot model tests,
which compare computations against pybullet.
## Code Contribution
We enforce linters for our code. The `formatting` test will not pass if your code does not conform.
To make this easy for yourself, you can either
- Add the formattings to your IDE
- Install the git [pre-commit](https://pre-commit.com/) hooks by running
```bash
pip install pre-commit
pre-commit install
```
For Python code, use [black](https://github.com/psf/black).
To enforce this in VSCode, install [black](https://github.com/psf/black), [set your Python formatter to black](https://code.visualstudio.com/docs/python/editing#_formatting) and [set Format On Save to true](https://code.visualstudio.com/updates/v1_6#_format-on-save).
To format manually, run: `black .`
