This code has been updated since the Arxiv paper was published. The code used to run the examples in that paper can be found under the arxiv_paper_version tag. That version was tested to work with Drake version 1.3 (although version up to 1.8 should work with some deprecation warnings).
Most of the examples and reproductions can be run on Deepnote.
After duplicating the project into your own account, be sure to run the MosekLicenseUpload.ipynb notebook to make your Mosek License available for solving the optimization problems.
Note: The PRM and Bimanual reproductions do not yet work on Deepnote and the UAV and Maze reproductions have been shrunk in size to avoid hitting memory limits on Deepnote.
This code depends on Drake, specifically its Python bindings. To install Drake bindings follow the instruction on Drake's Installation Page. Any of the installation methods listed should work. You can check that the installation was sucessful by following the instruction here.
We have used Mosek to solve most of the examples. To solve using Mosek, you'll need to give Drake access to a Mosek license file as described here. Mosek provides a personal academic license for free.
You will also need to install gcs and its dependencies. You can do this by running
pip install -r requirements.txt
Once all the dependencies have been installed, you can run the examples with jupyter notebooks which can be launched by calling
jupyter-notebook
from inside this repository.
If you want to compare GCS to sampling based planners (such as PRM), you'll need to install a custom fork of drake that includes bindings for sampling based planners. To do this run the following, including any of the proprietary solvers you have access to.
git clone -b gcs_paper [email protected]:wrangelvid/drake.git
mkdir drake-build
cd drake-build
cmake -DWITH_MOSEK=ON [-DWITH_GUROBI=ON -DWITH_ROBOTLOCOMOTION_SNOPT=ON] ../drake
make -j
Then add the built bindings to your Python Path using
For Ubuntu 20.04:
cd drake-build
export PYTHONPATH=${PWD}/install/lib/python3.8/site-packages:$PYTHONPATH
For macOS:
cd drake-build
export PYTHONPATH=${PWD}/install/lib/python3.9/site-packages:$PYTHONPATH
