Hi, I'm running your project, I used Xtion since it don't need the extra battery to drive it. It showed as follows: [ WARN] [1556805443.821747525]: Wait for tf: Kinect frame Writing 0 nodes to output stream...[ WARN] [1556805443.922125934]: Rotate... Writing 0 nodes to output stream...[ WARN] [1556805446.978718578]: Rotate... And when it turned around for a circle,it stopped and showed the error as the title.How should I fix this problem? Thanks in advance.

It seems you don't have depth image going into the exploration node. First check the Xtion sensor data is publishing, second do a remap for the depth topic (you might want to check in the source code to change it if you alway use Xtion sensor.)
