| 2015-09-03 08:04:08 -0500 | asked a question | How can I remap enitre roslaunch file? Hello, I have 2 real turtlebots (for now.. I'll have more in the near future) and I want them to run on one ros-master, since they have identical topics if I launch in one turtlebot the other get it also. for example if I launch turtlebot_bringup minimal.launch in one and afterwards in the other it will shutdown the first and open in the last. since that I've thought to create groups and remap the topics but since all the topics are the same it seems like allot of work. can I remap entire launch file without remapping every topic one by one? |

| 2015-08-05 04:25:22 -0500 | answered a question | Waiting on transform from base_footprint to map to become available I had the same problem because when i've saved my map I did it in the tmp directory (like in the tutorial) and then manually transfer it to other directory. If you did it too i advise you to copy the files again to tmp load it , and save it in other location by: rosrun map_sever map_saver -f /...your directory goes here.../you_map_name |
| 2015-08-05 04:18:16 -0500 | answered a question | Problem connect turtlebot and workstation So I've found a way to make it work, apprently the problew was in " what(): locale::facet::_S_create_c_locale name not valid process" the solution is by : " export LC_ALL="C" " in my understanding it means that the code is written in C (language). if anybody can tell otherwise i will be happy to learn. |
| 2015-08-03 04:47:08 -0500 | asked a question | Problem connect turtlebot and workstation Hello,
After I have followed the tutorials , the connection between my turtlebot2 and the workstation still doesn't work,
I have set ROS_MASTER_URI , ROS_HOSTNAME in both the workstation and the turtlebot netbook.
when I'm trying to do :
roslaunch turtlebot_bringup minimal.launch I get these errors: core service [/rosout] found process[robot_state_publisher-1]: started with pid [2978] terminate called after throwing an instance of 'std::runtime_error' what(): locale::facet::_S_create_c_locale name not valid process[diagnostic_aggregator-2]: started with pid [2980] terminate called after throwing an instance of 'std::runtime_error' what(): locale::facet::_S_create_c_locale name not valid process[mobile_base_nodelet_manager-3]: started with pid [2982] terminate called after throwing an instance of 'std::runtime_error' what(): locale::facet::_S_create_c_locale name not valid process[mobile_base-4]: started with pid [2984] terminate called after throwing an instance of 'std::runtime_error' what(): locale::facet::_S_create_c_locale name not valid [robot_state_publisher-1] process has died [pid 2978, exit code -6, cmd /opt/ros/hydro/lib/robot_state_publisher/robot_state_publisher __name:=robot_state_publisher __log:=/home/turtlebot/.ros/log/ed2507e6-39c0-11e5-9712-c4d987c9f05e/robot_state_publisher-1.log]. log file: /home/turtlebot/.ros/log/ed2507e6-39c0-11e5-9712-c4d987c9f05e/robot_state_publisher-1.log [diagnostic_aggregator-2] process has died [pid 2980, exit code -6, cmd /opt/ros/hydro/lib/diagnostic_aggregator/aggregator_node __name:=diagnostic_aggregator __log:=/home/turtlebot/.ros/log/ed2507e6-39c0-11e5-9712-c4d987c9f05e/diagnostic_aggregator-2.log]. log file: /home/turtlebot/.ros/log/ed2507e6-39c0-11e5-9712-c4d987c9f05e/diagnostic_aggregator-2.log process[cmd_vel_mux-5]: started with pid [2986] terminate called after throwing an instance of 'std::runtime_error' what(): locale::facet::_S_create_c_locale name not valid process[bumper2pointcloud-6]: started with pid [2988] [mobile_base_nodelet_manager-3] process has died [pid 2982, exit code -6, cmd /opt/ros/hydro/lib/nodelet/nodelet manager __name:=mobile_base_nodelet_manager __log:=/home/turtlebot/.ros/log/ed2507e6-39c0-11e5-9712-c4d987c9f05e/mobile_base_nodelet_manager-3.log]. log file: /home/turtlebot/.ros/log/ed2507e6-39c0-11e5-9712-c4d987c9f05e/mobile_base_nodelet_manager-3.log terminate called after throwing an instance of 'std::runtime_error' what(): locale::facet::_S_create_c_locale name not valid process[turtlebot_laptop_battery-7]: started with pid [2990] [mobile_base-4] process has died [pid 2984, exit code -6, cmd /opt/ros/hydro/lib/nodelet/nodelet load kobuki_node/KobukiNodelet mobile_base_nodelet_manager mobile_base/odom:=odom mobile_base/enable:=enable mobile_base/disable:=disable mobile_base/joint_states:=joint_states __name:=mobile_base __log:=/home/turtlebot/.ros/log/ed2507e6-39c0-11e5-9712-c4d987c9f05e/mobile_base-4.log]. log file: /home/turtlebot/.ros/log/ed2507e6-39c0-11e5-9712-c4d987c9f05e/mobile_base-4.log [cmd_vel_mux-5] process has died [pid 2986, exit code -6, cmd /opt/ros/hydro/lib/nodelet/nodelet load yocs_cmd_vel_mux/CmdVelMuxNodelet mobile_base_nodelet_manager cmd_vel_mux/output:=mobile_base/commands/velocity __name:=cmd_vel_mux __log:=/home/turtlebot/.ros/log/ed2507e6-39c0-11e5-9712-c4d987c9f05e/cmd_vel_mux-5.log]. log file: /home/turtlebot/.ros/log/ed2507e6-39c0-11e5-9712-c4d987c9f05e/cmd_vel_mux-5.log [bumper2pointcloud-6] process has died [pid 2988, exit code -6, cmd /opt/ros/hydro/lib/nodelet/nodelet load kobuki_bumper2pc/Bumper2PcNodelet mobile_base_nodelet_manager bumper2pointcloud/pointcloud:=mobile_base/sensors/bumper_pointcloud bumper2pointcloud/core_sensors:=mobile_base/sensors/core __name:=bumper2pointcloud __log:=/home/turtlebot/.ros/log/ed2507e6-39c0-11e5-9712-c4d987c9f05e/bumper2pointcloud-6.log]. log file: /home/turtlebot/.ros/log/ed2507e6-39c0-11e5-9712-c4d987c9f05e/bumper2pointcloud-6.log [WARN] [WallTime: 1438594577.419304] Battery : unable to check laptop battery info [global name 'exceptions' is not defined] [WARN] [WallTime: 1438594577.422830] Battery : unable to check laptop battery state [global name 'exceptions' is not defined] [turtlebot_laptop_battery-7] process has finished cleanly log file: /home/turtlebot/.ros/log/ed2507e6-39c0-11e5-9712-c4d987c9f05e/turtlebot_laptop_battery-7*.log all processes on machine have ... |
