So I ran: roslaunch gazebo_ros empty_world.launch

to start Gazebo in an empty world. The gazebo window pops up but the terminal stops at this: gazebo/set_physics_properties] has not been advertised, waiting...

Msg Connected to gazebo master @ http://127.0.0.1:11345 Msg Publicized address: 10.0.0.9 Msg Connected to gazebo master @ http://127.0.0.1:11345 Msg Publicized address: 10.0.0.9

Even after waiting for awhile, the terminal seems to be stuck at this point and does not allow me to type any commands. I've tried redoing the command multiple but it keeps stopping at the same point.

Can you install the PR2 robot simulator on ROS Indigo?

So I was trying to install ROS Indigo on ubuntu 13.1 but I keep getting the following error:

Reading package lists... Done
Building dependency tree       
Reading state information... Done
Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created

The following information may help to resolve the situation:

The following packages have unmet dependencies:
 ros-indigo-desktop-full : Depends: ros-indigo-desktop but it is not going to be installed
                           Depends: ros-indigo-perception but it is not going to be installed
                           Depends: ros-indigo-simulators but it is not going to be installed

Any help would be appreciated.

Hi all,

I was wondering if there were any tutorials online that would help me move the arm for the PR2 robot in Gazebo. I tried a lot of tutorials already but all of them seemed outdated with the code and all. Any help at all would be appreciated.

I am trying to proceed with this tutorial but when I run sudo apt-get install ros-electric-pr2-arm-navigation I get the following error:

Reading package lists... Done
Building dependency tree       
Reading state information... Done
E: Unable to locate package ros-electric-pr2-arm-navigation

Help would be appreciated. :)

So I am trying to control the Pr2 arms with this tutorial.

After I run the very last command, I get the following error:

[ rosmake ] rosmake starting...

Help would be appreciated.

So I ran the line roslaunch gazebo_ros empty_world.launch

So now I have an empty world and spawned a pr2 robot. How would I go about making the robot do something? For example waving? Do I just type commands in a new terminal? Very new to ROS :(

Thanks

Hello,

I'm a complete newbie to ubuntu, ros, and the pr2 robot simulator. How can I write a simple program to make the pr2 robot do something in simulation? An example with an explanation of the code/how to run it maybe?

Thanks.

I have ubuntu 13.04 and ros hydro. I mean how do you run code on the pr2 in the simulation? This link gave me a list of commands you can run for example pr2.openGripper(side) will open one of the grippers. I was wondering where you type these commands in.

Where is the command interface for the pr2 robot simulator?

The tutorials don't seem to help.

Help would be appreciated. Thanks :)

So at this link: http://wiki.ros.org/robot_script , commands for making the pr2 robot simulator perform certain actions are given. Where would I write this code and how would I run it so that the pr2 robot on the gazebo simulator performed these tasks?

Detailed instructions would be appreciated :)

when I run rostopic echo /base_controller/command it says "WARNING: no messages received and simulated time is active.Is /clock being published?"

when I run rostopic echo /cmd_vel it says "WARNING: topic [/cmd_vel] does not appear to be published yet". There also seems to be no "/base_controller/command" topic.

This may sound like a dumb question, but how do you check that? Certain lines of code that I run?

Yea I am not sure what is going on. The keyboard controls are still not working.

I was looking at this tutorial:http://wiki.ros.org/pr2_simulator/Tutorials/BasicPR2Controls And it said: "(You need to keep the window in which you launch this node in focus while you drive the robot around)."

What does it mean by keep the terminal in focus?
