Could you please explain how you changed format from mjped to yuyu?

I am having exactly the same problem. How did you ping from robot side? Did you use Touch Panel i.e. PolyScope ?

I am facing very unusual problems. I have been using ROS-Indigo under Ubuntu 14.04 on my Virtual Machine and ROS-Indgio under Ubuntu 14.04 on my laptop. Surprisingly, I am seeing totally different kinds of errors on all of these machines while I am using the same tutorials.

Coming to the point, I am trying to run PR2 moveit tutorials given here. On my laptop, I am seeing the following error

PluginlibFactory: The plugin for class 'moveit_rviz_plugin/MotionPlanning' failed to load.  Error: According to the loaded plugin descriptions the class moveit_rviz_plugin/MotionPlanning with base class type rviz::Display does not exist.

and the following error

Exception while loading planner 'ompl_interface/OMPLPlanner': According to the loaded plugin descriptions the class ompl_interface/OMPLPlanner with base class type planning_interface::PlannerManager does not exist.

It is really very frustrating. So, I tried to run it on my virtual machine as well. Please help me, how can I handle this. I have been spending a lot of time on it and it is not working.

Hi,

I am trying to use a package Youbot Simulation. The problem is that it asks me for brics_actuator. I have tried using this link and this link.

I shall be very thankful to you if someone could give me some clue to help me resolve this.

I am using ROS Kinetic.

Thank You in advanced.

=========== Edit 1 ==============

After using this link, I got the following error,

I believe that I have to enable C++11. Could you please tell me how did you do it? I think the error which I was receiving previously has been removed.

Please excuse me if my question is too basic. I have gone through ROS control package and moveit etc. But, I want to test my own controller. My question is simple. How can I do this? For example, I want to write my controller like

M(q)q_ddot + C(q,q_dot)q_dot +G(q) = tau

and so I design my control law "tau" as

tau = M^-1(a_q) + C(q,q_dot)q_dot + G(q)

Can anyone guide me for the steps I should take? I have modeled my robot in ROS using URDF etc. Now, I want to evaluate my own control law.

I have been following book Learning ROS for robotics programming and Mastering ROS for robotics programming but I could not understand this. Your words will be highly appreciable. Thanks.

I guess turtlebot3 simulation has been released for melodic.

Hi,

I am facing a problem in running tutorials given in the book: Mastering ROS in Robotic Programming, Chapter 2.

I am using Ubuntu 16.04 with ROS Kinetic. In particular, when I run my launch file as

khan@khan:~/catkin_ws/src/mastering_ros_robot_description_pkg/launch$ roslaunch mastering_ros_robot_description_pkg view_arm.launch

The following error occurs.

unknown macro name: xacro:base 
XacroException(u'unknown macro name: xacro:base',)

I have checked the file again and again and there is nothing I changed. It is the tutorial files. I don't know why it is not running. Please, suggest any help. Thank you so much.

You don't need to do that. Just go into your source file like cd ~/catkin_ws cd src in source file clone pr2 like t

I am using ROS-Kinetic under Ubuntu 16.06. I am constantly seeing this error in my screen.

ERROR: cannot launch node of type [interactive_marker_twist_server/marker_server]: interactive_marker_twist_server

I have gone through this Link and it shows this package is available for indigo and jade only. I tried but it does not work with Kinetic. I don't want to develop my expertise for indigo. Please, help. Thanks in advance

Hello, I am studying the book for beginners to understand ROS. When I compile chapter 5 tutorials, I face this problem.

/home/khan/catkin_ws/src/chapter5_tutorials/src/homography.cpp:16:39: fatal error: opencv2/nonfree/nonfree.hpp: No such file or directory

To resolve this problem, I have already gone through the following method mentioned herelink text

sudo apt-get update
sudo add-apt-repository --yes ppa:xqms/opencv-nonfree
sudo apt-get update
sudo apt-get install libopencv-nonfree-dev

but in following that method, I got another error such as

  E: Unable to locate package libopencv-nonfree-dev

to resolve this problem, I followed the method mentioned here as

sudo gedit /etc/apt/sources.list

and then make its backup and further change by adding these lines into the source.list file

deb http://kr.archive.ubuntu.com/ubuntu precise main restricted universe
deb-src http://kr.archive.ubuntu.com/ubuntu precise restricted main multiverse universe
deb http://kr.archive.ubuntu.com/ubuntu precise-updates main restricted universe
deb-src http://kr.archive.ubuntu.com/ubuntu precise-updates restricted main multiverse universe

and then finally updating it with

sudo apt-get update

After going through this whole method, still I am seeing this error

W: Failed to fetch http://ppa.launchpad.net/xqms/opencv-nonfree/ubuntu/dists/vivid/main/binary-amd64/Packages  404  Not Found

Please, help me in it, I have spent plenty of time in figuring it out and still my chapter5 tutorials are not being compiled. I shall buy cookies for you. :)

After going through the method explained by Dear Jarvis Schultz, I followed this problem further and I am getting this message. @Jarvisschults. i.e. undo the changes I made in source.list and run the following.

sudo add-apt-repository ppa:xqms/opencv-nonfree

I am getting this message. 

Please be aware of potential patent issues when using this PPA. For a list of included algorithms see:

I guess it is worth mentioning that I am using Linux 15.04 under ROS Jade with graphic card NVIDIA GeForce GT630. I feel there might be some issue with it as I read it from this link in which the message is,

please do not advise users to add the Proprietary GPU Drivers PPA when it is not necessary, the nvidia-352 drivers are available in the official Ubuntu repositories. Adding this PPA is an option when these drivers don't work properly and you want to install the latest official stable NVIDIA drivers from the NVIDIA short-lived branch.

I am using Ubuntu 15.04 and jade version of ROS. I am trying to use the usb camera by the method given in the book on page 187. My camera is already good and I checked it by the "cheese" method explained in there. Here is what I am doing

$ sudo apt-get install ros-jade-usb-cam

$ roslaunch chapter5_tutorials usb_cam.launch view:=true

here is what I am getting after doing this

[ERROR] [1453172400.684518103]: Webcam: expected picture but didn't get it...


[ERROR] [1453172400.684518103]: Webcam: expected picture but didn't get it...

Can any please tell me, how can I solve this problem? After getting Stefan Kohlbrecher; I am going to add the steps I took. Thank you so much Stefan Kohlbrecher for your kind response. Here is what I followed from your prescribed solution from here and here and also from here.

rosparam set usb_cam/pixel_format yuyv
roslaunch chapter5_tutorials usb_cam.launch view:=true

and here is what I got,

[ERROR] [1453352737.003836186]: Webcam: expected picture but didn't get it...
[mjpeg @ 0x1ffd7c0] mjpeg: unsupported coding type (cd)
[ERROR] [1453352737.043623383]: Webcam: expected picture but didn't get it...

I don't know why the code, commands and method shown in book is still not working.

I thoroughly followed all the instructions given on chapter 4 of the book (Learning ROS for Robotics Programming 2nd edition) on Jade. That's the error I am seeing ![image description]. I have also followed all the instructions given in ROS tutorials ( http://wiki.ros.org/joy/Tutorials/Wri... ) but doing this giving me another type of error i.e. dynamaximal driver not installed. If possible please help me for any of it.

I am using ubuntu 15.04 on Jade. Thanks in advance.

No. Please let me know if you solve this problem.
