Robot soccer simulator based on FiraSim and GrSim.
Simulates games from LARC Very Small Size and RoboCup Small Size leagues.
$pip install rc-robosimCurrently wheels are distributed to manylinux2010 for python 3.7-3.10. If your environment does not have available wheels it will download from source and attempt to build it, which will require having ODE version 0.16.2 library installed with libccd collisions
$git clone [this repo]
$cd rSim
$pip install .This will also require having ODE 0.16.2 with libccd installed
