I publish my occupancy_grid on /local_grid topic from the grid_construction_node and then I want to use this occupancy grid to start at current robot location and to go to /global_goal which is set as 5,0 by my obs_husky node.

The elements of mapData are not integers but they are of the form:\r\n0x7f8ad8002990\r\n0x7f8ad8002f30\r\n0x7f8ad8000c10\r\n0x7f8ad8003aa0\r\n0x7f8ad8003570\r\n0x7f8ad80044b0\r\n0x7f8ad8003f80\r\n0x7f8ad8004f10\r\n0x7f8ad80049e0\r\n\r\nSo mapData[curY][curX]==100 is never true.
