My environment is Ubuntu 20.04 with ROS Noetic. As the standard Kobuki packages (ros-noetic-kobuki, and ros-noetic-kobuki-gazebo) are not be readily available, I use source installation through:
git clone https://github.com/yujinrobot/kobuki.git
git clone https://github.com/yujinrobot/kobuki_desktop.git # For kobuki-gazebo
But when I try to test rrt_exploration_tutorials, the above errors occurred and Gazebo cannot be loaded.
