I have been trying to get Explorer Lite on my robot that works with movebase but keep running into issues where the node returns "found 0 frontiers" and stops exploration. The following is sample cost map that I saved in the searchFrom(...) function using costmap->saveMap(std::string("~/costmap.pgm"));
Up on further investigation I found that isNewFrontierCell(...) never gets called. I have attached a small bag file from my robot, along with the yaml files we used. Any advice on how to resolve this bug would be helpful.
