2014-01-23 23:13:22 -0500 answered a question What must I do to use my code on a turtlebot?

Hello again, so now I finished all the tutorials and I want to start writing my own code for the turtlebot. First thing I want do is to give it a value for the forward speed with a certain time, before I was going to start coding. I tried this:

roscore

In a new terminal ssh turtlebo@tb1 roslaunch turtlebot_bringup minimal.launch

Neither on my Laptop nor on the turtlebot this was working, the turtlebot wasn't moving at all

rostopic pub /mobile_base/commands/velocity geometry_msgs/Twist -r -- '[2.0, 0.0, 0.0]' '[0.0, 0.0, 2.0]

Where is my mistake, what did I do wrong?

Thank you, that was the problem I did not know how to program in ROS. Luckily I did find it ^^

Ok I might have found something, I am doing the catkin tutorial, I guess that how I can use my own codes can't I?

Well I did the installation, follower, mapping and so on tutorials. And then I wanted to use my own code for those things, but I did not see andy tutorials, that explain how to do it or at least I haven't seen any

I had got the same problem, the kinect was mounted in a wrong way. I just changed it and all was fine ;-)

Hello,

I want to write some code for my turtlebots and I am an absolute beginner I did some of the tutorials but I haven't found anything (or my English is not good enough), that describes what I need to do if I have got an own code? What do I need to do if I have a my code, what is the next step? Are there any tutorials for that I haven't seen yet?

Thanks for your help ;-)

'[x, 0.0, 0.0]' '[0.0, 0.0, z]' I did solve it, I do not know why, but it works if x < 1.7

Does anybody know why?

I tried this http://wiki.ros.org/Robots/NXT/electric , but 1.4 Setup your sources.list there is only mentioned Ubuntu 11.10 (Oneiric), so how can I install it on 13.04?
