New to ROS as well as LINUX.

asked 2012-05-04 01:20:20 -0500

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.

You can find everything you need to know in the form of tutorials on the official ROS site here:

http://www.ros.org/wiki/ROS/Tutorials

I don't actually know why you started with website you mentioned on your question, but this is apparently about how to configure ROS Diamondback with the Ganzebo simulator and several other packages and NOT about how to get started with ROS. I also recommend you to install the newest ROS release Fuerte like it is explained here:

Maverick (Ubuntu 10.10) is not supported in Fuerte. If @srj0408 really wants to stick with Maverick, Electric is the newest compatible ROS distribution.

@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

You should first go through the tutorials ( http://www.ros.org/wiki/ROS/Tutorials ) to know how ROS works. After completing those, you can go to the ROS package of the Gazebo simulator and start working. Having done the tutorials, you will know how to get this started...

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.

@srj0408 If you want to run simulations of robot,maybe you can see this pages(http://www.ros.org/wiki/Robots) and find tutorials to follow~

I agree with your view.I lead 9 people writing some applications with ROS and I found it is really not easy to follow tutorials and really found what to do can really understand ROS and use the full power of ROS. When I just look,I found that ROS doc seems provide everything,but hard for self learn.

@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

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.

I have no way to add info to ROS docs. So if you have questions, you just feel free to open a thread to ask. It is better to ask the questions(with text and keyword) when you really read the ROS tutorials you don't understand. If you ask good questions, maybe can make ROS tutorials more clearly.
