example_anymal_contacts
example_anymal_contacts creates a raisim::World, adds ground, loads
rsc/anymal/urdf/anymal.urdf, applies PD gains to the leg joints, and
publishes the simulation through raisim::RaisimServer.
Run rayrai_raisim_tcp_viewer in one terminal, then run the example in another:
<raisim-install>/bin/rayrai_raisim_tcp_viewer
<raisim-install>/bin/example_anymal_contacts
The example runs for 20 seconds and focuses the viewer on the ANYmal model.
