Hello;
i am trying to simulate robot like explained in readme.So i typed followings:
mkdir -p test_ws/src
cd test_ws/src
catkin_init_workspace
git clone --recursive https://github.com/stack-of-tasks/talos_integration_tests.git
cd ..
catkin config --install
Untill here everything went well.After that i typed like here and get some errors:
