Reproducing the experiments

We support running the experiments via the provided Docker image.

1. Pull the docker image:

   docker pull ghcr.io/ami-iit/dcc-planner-docker:latest

2. Launch the container:

   xhost +
   docker run -it --rm  \
              --device=/dev/dri:/dev/dri \
              --user user \
              --env="DISPLAY=$DISPLAY"  \
              --net=host \
              ghcr.io/ami-iit/dcc-planner-docker:latest

3. The application will start automatically

The videos and the data from the experiments will be saved in the folder ../SavedVideos.

It is possible to run tests with different parameters by running the following command

OMP_NUM_THREADS=1 cpp_ws/build/dynamical-planner/bin/SolverForComparisonsUnitTest [options]

with [options] being:

  -s, --solver                                Linear solver to use with ipopt (string [=mumps])
  -c, --complementarity                       Type of complementairity condition (string [=dynamical])
  -v, --velocity                              Linear walking velocity (d [=0.05])
      --normalForceDissipationRatio           Normal Force Dissipation Ratio (one of the two parameters of the hyperbolic complementarity method). (d [=250])
      --normalForceHyperbolicSecantScaling    Normal Force Hyperbolic Secant Scaling (one of the two parameters of the hyperbolic complementarity method). (d [=500])
      --complementarityDissipation            The rate of dissipation for the complementarity (one of the two parameters of the dynamical complementarity method). (d [=20])
      --dynamicComplementarityUpperBound      The upper-bound for the dynamic complementairty (one of the two parameters of the dynamical complementarity method). (d [=0.05])
      --classicalComplementarityTolerance     The upper bound for the classical complementarity. (d [=0.004])
  -?, --help                                  print this message

⚠️ In the docker image provided, only the linear solver mumps is supported.

⚠️ If you want to replicate the installation on your PC please follow the Docker recipe.
