Hey kartik,after going through your instaruction ,gazebo was installed but with certain warning regarding dependencies,

WARNING: Rosdep did not detect the following system dependencies as installed: libqt4-dev, yaml, libqt4-opengl-dev, libtool, tbb, fltk Consider using --rosdep-install option or rosdep install gazebo.

now to install there dependencies i should write a command like sudo apt-get install libqt4-dev.

Am i right?

hey kartik,

hey kartik, after going through your instruction to instal gazebo,it was being installed but with a warning.

Hello Kartik, Thats what i am doing till now,but things get a bit complicated when we had to deal with certain other things.I am going through the tutorials provided in ROS wiki.

Hello kartik, I am new webbie to both ROS and LINUX.I think i hadnt installed ros-electric-desktop-full,and even i dont know how to find the current version of installed ROS version.But i am very sure that Gazebo dosent come with my installed version because after following the instruction given to launch Gazebo,it dosent work and there come some errors declaring that i hadnt installed Gazebo.

Secondaly after going through the instruction provided in the http://www.ros.org/wiki/gazebo,its quite tough for me to install gazebo.If you can help me by exlaning it a bit than that will be helpfull for me.

Thanks for the reply.

while installing Gazebo simulator in ROS electric,this statement is given on Gazebo wiki page,ROS Users: Never install gazebo from here. Use these instructions. ,and when we click on the folowing link,it direct us to ROS installation page where no information is being given for the installation of Gazebo simulator,Kindly help me to overcome this situation.........

Hello all, i am done with installing and making turtle sim package,but i am geting no idea,how to move further,can any body help me.How this turtle sim can be helpfull in learning things about robotics.?

hey Lorenz, thanks for the reply,i think i was doing certain mistake,or i think due to some reasons i wasnt able to navigate from my home directory to ros_workspace,problem is solved now,thanks for the reply and sorry for that silly question as i am very new to ros as well as linux

I am trying to go through tutorial to create a new package in current directory which is i think ROS, but getting following mistake,can someone help me out in this

Hey everybody, Can any body tell me where to find the link for Gazebo simulator or any other simulator and its related documentation?

@joq:- Well i do have electric installed to in my UBUNTU10.10.But i am not getting what to do next,because there are many confusing tutorials in that.Means after that how should i continue with simulators as obiviousaly i dont have harware to work with,what about the coding to be done for simulation

so if someone can help us to understand thing in a proper manner,like which package to be installed,then where to do coding,then where to see simulation,then i will be obliged.

@sam:- yup you are right,like in easy to understand way,we do install a software,we do have a editor,we write code,we compile code and if we had simulator we can see the compiled code simulation in the simulator ,you can take example of ANDROID sdk

hey michikarg, Thanks a lot for your reply.But in that website where we had to install ROS diamondback,everything is given,what to do after installing diamond back where as in ROS tutorials given on ROS website,i didnt find anything clearly,so its a bit dificult.Can you help me how to get started with that? Means what i asked,how can we simulate any of the robot,bcz i think its all regarding getting everything done related to actual robot as a simulation rather than doing it in real time using hardware.

Hello everybody, This is Shailendra singh from India.I am very new to ROS+LINUX.Till now i was working with windows,embedded system and simple manual robotics using AVR series 8 bit micrcontrollers.But to get myself updated according to the latest trends of RObotics,i started learning ROS.I started with installing ubuntu10.10.Then i installed ROS using command $ sudo apt-get install ros-fuerte-desktop.this installed ros of 728 mb in my system.Than i started working with the help of https://wiki.nps.edu/display/~thchung/Setting+Up+a+Clean+Installation+of+ROS but i find that i am not getting anything.Is there any tutorial availiable with the help of which i can start step by step.I know i am asking very silly question,but need help in that.Its quite confusing. i) I understand the use of ROS,its basically used to simulate robots rather than testing them in real time. ii) Wheres the coding part? iii) And how should we start?

if someone can give those answers i think it will be too great for new webbies to understand things too easily.
