rubber bread's profile - activity

I learnt ROS By Example recently,and I have some problem with keyboard_teleop.launch

roslaunch rbx1_nav keyboard_teleop.launch

The launch file:

    <launch>

  <node pkg="turtlebot_teleop" type="turtlebot_teleop_key" name="turtlebot_teleop_keyboard" output="screen">
    <param name="scale_linear" value="0.1" type="double"/>
    <param name="scale_angular" value="0.4" type="double"/>
    <remap from="turtlebot_teleop_keyboard/cmd_vel" to="cmd_vel" />
  </node>

</launch>

However , I run this launch ,the terminal shows

ERROR: cannot launch node of type [turtlebot_teleop/turtlebot_teleop_key]: can't locate node [turtlebot_teleop_key] in package [turtlebot_teleop]

Before I run this launch ,I run

roslaunch rbx1_bringup fake_turtlebot.launch
rosrun rviz rviz -d `rospack find rbx1_nav`/sim.rviz

How to fix it?

Thanks

Hi,all I use kobuki robot. Recently I have a problem. I read ros-by-example recently , and I found that the .launch file that connect robot(roslaunch rbx1_bringup turtlebot_minimal_create.launch) can't connect my kobuki robot. I don't know how to fix it.Any one can help me ? following is the file turtlebot_minimal_create.launch script

  <launch>
  <arg name="base"       default="create"/>  <!-- create, rhoomba -->
  <arg name="battery"    default="$(optenv TURTLEBOT_BATTERY /proc/acpi/battery/BAT0)"/>  <!-- /proc/acpi/battery/BAT0 -->
  <arg name="stacks"     default="circles"/>  <!-- circles, hexagons -->
  <arg name="3d_sensor"  default="asus_xtion_pro"/>  <!-- kinect, asus_xtion_pro -->
  <arg name="simulation" default="$(optenv TURTLEBOT_SIMULATION false)"/>

  <param name="/use_sim_time" value="$(arg simulation)"/>

  <include file="$(find turtlebot_bringup)/launch/includes/robot.launch.xml">
    <arg name="base" value="$(arg base)" />
    <arg name="stacks" value="$(arg stacks)" />
    <arg name="3d_sensor" value="$(arg 3d_sensor)" />
  </include>

  <include file="$(find rbx1_bringup)/launch/includes/tb_create_mobile_base.launch.xml" />

  <include file="$(find turtlebot_bringup)/launch/includes/netbook.launch.xml">
    <arg name="battery" value="$(arg battery)" />
  </include>
</launch>

This is my own kobuki connect launch file script

  <launch>
  <arg name="mobile_base" default="$(optenv MOBILE_BASE create)"/>
  <!-- create, kobuki -->
  <arg name="base_port" default="$(optenv BASE_PORT /dev/ttyUSB0)"/>
  <!-- /dev/ttyUSB0, /dev/ttyS0 -->

  <param name="/use_sim_time" value="false"/>

  <!-- mobile base setting -->
  <include file="$(find aicroboxi_bringup)/launch/includes/$(arg mobile_base)/mobile_base.launch.xml">
    <arg name="base_port" value="$(arg base_port)" />
  </include>

  <!-- aicroboxi_description -->
  <include file="$(find aicroboxi_description)/launch/robot_description.launch.xml">
    <arg name="mobile_base" value="$(arg mobile_base)" />
  </include>
</launch>

Thanks again!

OK, I'll try.Thanks

I have already finished reading the beginning tutorials. I can teleop my turtlebot now.

Hi,all. I have two Yujin Kobuki robots. And I came up an idea today,but I don't know how to make it realize. The idea is that:I want a kobuki robot follow another kobuki robot. I can use keyboard to control the front robot , and the robot behind will follow the front robot automatic. How can I make it realize? I learn ROS only 3 months. And I don't know how to write a package, how to use others package on my own robot. I hope some one could give me some idea, or send me a package which will work correctly on my kobuki, so that I can learn from it.Thanks a lot. My email address is huangshiw@126.com . I would appreciate it if you can send the package by email. △the package: turtlebot_follower doesn't work on my kobuki :(

Hi,all I install ros-by-exanple-indigo code on my computer.And I prepare to test fake robot simulator.However,Once I run the .launch file there will be a mistake in rviz.See follow.

run command:

 roslaunch rbx1_bringup fake_turtlebot.launch

then run

rosrun rviz rviz -d 'rospack find rbx1_nav' /sim.rviz

then there's a mistake in rviz, Global Status ：error

fixed frame :fixed frame [map] do not exist

Thanks a lot.After I runsudo apt-get install gstreamer0.10-gconf it worked

sorry,there're some mistakes with my Firefox.I can't upload the question (However, it has already uploaded) So ,the question uploaded like repost.

Hi,all I install ros-by-exanple-indigo code on my computer.And I prepare to test pocketsphinx for speech recognition.However,Once I run the .launch file there will be a mistake which will kill the program.Steps and mistakes as follow.

Hi,all I install ros-by-exanple-indigo code on my computer.And I prepare to test pocketsphinx for speech recognition.However,Once I run the .launch file there will be a mistake which will kill the program.Steps and mistakes as follow.

run command:

 roslaunch pocketsphinx robocup.launch

terminal display:
