Robot is not moving to goal

I have a simulation in gazebo with two husky robots. I launch move_base_mapless_demo.launch file so i can send goals to a robot. When I'm using simulation with one husky robot, it moves to correct spot, but when there are two husky robots then the robot never reaches its goal and it never stops. I don't use any map although i thought that is causing the problem... I use this command to move robot to a goal rostopic pub /husky2/move_base_simple/goal geometry_msgs/PoseStamped '{header: {stamp: now, frame_id: "/husky1_tf/odom"}, pose: {position: {x: 1.0, y: 0.0, z: 0.0}, orientation: {w: 1.0}}}' this is my move_base launch file i believe the problem is in frames but I don't quiet understand what should I do to fix the problem. Basically, I want husky2 to go to a goal when there's other robot. frames.pdf looks good to me. map -> husky1_tf/odom -> husky1_tf/base_link map -> husky2_tf/odom -> husky2_tf/base_link
