In the tutorial:

wiki.ros.org/urdf/Tutorials/Create your own urdf file

In which directory do I have to create my_robot.urdf file?

I created in my home directory (mudassar) and it did not successfully execute following commands:

rosmake urdfdom_model

check_urdf my_robot.urdf # hydro

Could you please guide the possible reason?

MY ros is hydro and I am using ubuntu 12.04LTS.

Could you please guide what necessary steps do I need (in general) to convert a MS Visual Studio 2010 code of C++ into ROS node in Hydro? Any reference?

Can I control the speed of ros running on my PC? I have ros hydro installed on ubuntu 12.04 LTS. For some reason, I wish to change the speed of ros running on my system (say i wish to speed up or speed down the code-running at the back end of my ros package, i.e; controlling the ros running speed). Is that possible?

A solution without modification of package code is highly desirable.

Please note that my answer is valid only for ROS Hydro on Ubuntu 12.04. I did not claim the answer for ROS indigo on Ubuntu 12.04.

In your Ubuntu Desktop page, goto (in left vertical bar of icons):

Ubuntu Software Center -> Edit -> Software Sources -> (Here Select in Download from:) Server for United States.

After doing this and saving, follow the installation procedure given here:

http://wiki.ros.org/hydro/Installatio...

This should install without any errors now. The reason why your ROS didn't install initially may be due to 'Software Sources' which did not contain updated repository for Hydro. I hope this works now. Best Wishes!

PS: It is not necessary that you only select Server for United States all the times. It depends on which server the complete package is available. Right now, it is available at Server for United States.

How can I change packages when they are already installed in my Ubuntu 12.04 LTS? I am using ROS Hydro. I had installed http://wiki.ros.org/rl-texplore-ros-pkg . It is working fine. But I need to change the package for some reason. I tried by changing src files only in installation path but this did not work for me. How can I change the installed package then? Please guide in detail.

Thanks!

I want to install the ros-pioneer3at in ROS. I downloaded the file from the URL

https://github.com/dawonn/ros-pioneer3at

but I don't know where to put it and how to install the package. I followed the procedure of

https://github.com/tu-darmstadt-ros-p...

for my package ros-pioneer3at but at wstool merge ros-pioneer3at_catkin.rosinstall it gives an error

ERROR in config: Yaml for each element must be in YAML dict form

I tried to install the hector_slam package in the similar manner, but again same error at the same point. Kindly guide how to resolve the issue.

Many thanks in advance!

When I run: wstool merge hector_slam_catkin.rosinstall

There is an error: ERROR in config: Yaml for each element must be in YAML dict form

Kindly help me to resolve!

I have installed ros hydro and have been using it correctly. BUt after some days, I got a problem. Now whenever I open a terminal, it says:

bash: /home/mudassar/ros/setup.sh: No such file or directory bash: /opt/ros/electric/setup.bash: No such file or directory bash: /opt/ros/electric/setup.bash: No such file or directory bash: /opt/ros/electric/setup.bash: No such file or directory bash: /opt/ros/electric/setup.bash: No such file or directory

Could anyone help to resolve my issue? Is there some problem in my .bashrc file? Please be detailed as I am very new to ubuntu and ros. Thanks!

Creating a ROS package by hand.(ROS Tutorial 1-Intermediate level)

catkin_ws_top $ mkdir -p src/foobar

The Error is:

catkin_ws_top: command not found

Kindly help!

Dear dnth, I myself need to use texplore package to implement it on some simple robot in gazebosim. Please guide how should I start. It would be highly appreciated if you can send me your email address as well as I hope to be using texplore (rather learning to use it) for next 5 to 6 months! My email address: mctncontrol@gmail.com

There is a dot missing in the second tutorial.

From your catkin workspace, run: ./devel/lib/testbot_description/parser ./src/testbot_description/urdf/my_robot.urdf

It worked for me.

I have Ubuntu 12.04 LTS and ROS Hydro. I installed Gazebo 1.9 and executed initial mobile robot tutorials with SDF. But my system gets very slow while running Gazebo. I have 1GB RAM with Intel Pentium (R) Dual CPU E2200@ 2.20 GHz*2. My motherboard is: ASUS P5KPL-AM EPU. Is there a minimum requirement for CPU and RAM while running Gazebo? What is that? Should I increase my RAM?

Still not working for me. An error of more or less the same type appears!

In tutorial :

http://wiki.ros.org/urdf/Tutorials/Pa...

When I run:

~/catkin_ws$ ./devel/lib/testbot_description/parser /src/testbot_description/urdf/my_robot.urdf

I get:

[ERROR] [1391452425.205963339]: Could not open file [/src/testbot_description/urdf/my_robot.urdf] for parsing.
[ERROR] [1391452425.206094879]: Failed to parse urdf file

I checked in the directories, both files are already present but still error! Kindly help!
