not a full answer, but you might check the SDFormat code, or possible the gazebo_ros_pkgs code

2020-01-15 13:41:29 -0500 marked best answer How to rebuild ign-msgs for gazebo9?

I've install gazebo9 on a Bionic machine which has more up to date versions of protobuf than gazebo is expecting. Specifically, the apt package for ign-msgs1 was compiled with something before protobuf 3. So naturally, I'm trying to rebuild ign-msgs1 so that it will be up to date. However, this fails because there are macros in ign-msgs1 Utils.cmake which are defined by ign-cmake0 in IgnUtils.cmake. This conflict makes it impossible to rebuild ign-msgs1 on Bionic.

I can't upgrade from ign-msgs1 without recompiling everything else, so I'm wondering if there's a way to make ign-msgs use its own macros instead of getting them stomped on by ign-cmake0

The collision the bump sensor is checking for is state to be sensor_collision, but I don't see that collision anywhere.
