 The cache size can be controlled with an absolute cap (`max_cache_size`) or with a distance threshold on the end effector pose (`min_pose_distance`) or robot joint state (`min_joint_config_distance`). Normally, the cache files are saved to the current working directory (which is usually `${HOME}/.ros`, not the directory where you ran `roslaunch`), in a subdirectory for each robot. Possible values for `kinematics_solver` are:
