hiro64's profile - activity

Can't you copy the openni launch file to your own folder and pass that argument inside it?

Hi there, When you pair the devices and make sure the Internet Access profile is enabled on Android, do you just connect to the PC as usual by inputting the ROS_MASTER_URI in the android app? When I do this, the android topics still don't appear when using rostopic list in the PC.

So I ended up connecting them through a hotspot created by another Android device, without any data connection involved, which finally did work. However, this is not an answer to my question, which was about USB or Bluetooth, so I'll just keep it here as an alternative solution.

Through USB I couldn't get it working any way, either through tethering or reverse tethering. WIth Bluetooth, I tried to use the Bluetooth Manager to share a connection from the PC, but also to no avail.

Hi,

Lately I have been trying to use the catkin_make command, with no luck. It seems some of the packages in the stacks folder have been given the same name, and so I cannot compile correctly. Now, I can't remove these, as they are shared with some co-workers, and I do not know if they are using them. So, is there some other choice for me to be able to compile on my catkin_workspace?

This is the message from catkin_make:

Using ROS Groovy and Ubuntu 12.10.

Thanks for your attention.

Are you sure your computer has that version of python installed? Maybe the problem lies with your python installation then.

Have you tried manually installing the listed packages through apt-get?

So, reverse tethering only worked when the notebook was connected to the internet. Otherwise, the topics simply don't appear to the master, even though the ROS android app does connect normally.

Have you followed the beginner tutorials? They are quite good and well-built, and cover catkin as well: http://wiki.ros.org/ROS/Tutorials

Haven't you asked the same thing in here?

It seems you do not have any C++ compilers installed. You must first install one to use catkin like this. Try opening up a terminal and then typing:

sudo apt-get install build-essential -y

Then the g++ compiler should be installed.

Yes. When I try to tether the tablet with the laptop (Ubuntu), it appears as a Wired Connection. Then I disconnect from the other connections and connect only with this Wired Connection.

The connection does show up in ifconfig. I should try your other suggestions, thank you.

I tried both ways, but it still didn't work. They connect to each other and even show up in the connected devices list, but no nodes or topics from the android device appear to the master at the laptop.

Hello,

I have been trying lately to connect a ROS core in my laptop with a ROS android app on my Galaxy Tab 2. Wi-fi is not possible because we do not have internet in the places where we need to move the robot. So I have tried to connect via USB, as I read that through USB tethering one could confirm this connection. However, I could not succeed in this, as the tablet does connect to the core, but does not appear to the master at the laptop (the topics and nodes from the android app do not appear as they do when using wi-fi).

Is there any more information about how to do this connection via USB? Or maybe through bluetooth, which I didn't find any at all.

Thanks.

If anyone gets into this situation, I have solved it by taking the headers (sound_play.h and SoundRequest.h) directly from the sound_play package and using them as part of the src of my package. This way, one is able to use their functions and the SoundClient class.

Hello,

So, I have been trying for a moment to compile a catkin package written in C++ which would use the sound_play package API, but it seems never to find the header <sound_play sound_play.h="">, even though the sound_play package is installed and works normally through rosrun. I have tried to use rosmake in the sound_play package, and can see that the header is indeed in the right place, but still catkin can't find it. Maybe I am forgetting to add an include somewhere? This is ROS groovy I am using.

Thanks for any suggestions.

Oh, how sad for me haha But thanks. Would you happen to know any other way for me to either synthesize voice or play sound files using catkin on groovy?
