2016-05-11 07:06:19 -0500 commented question package 'openni-dev' not found

Hi,

I disagree that this is a pcl question - my pcl is linked and running just fine. But when running catkin_make I get this error. Completely related to ROS.

2016-05-11 02:12:04 -0500 asked a question What is the correct way to commit clean a workspace before commiting?

Hi,

I work with svn and git and instead of committing my whole catkin workspace with built binaries etc, what is the best way to clean the worskpace before committing it. So that when someone else checks it out they just source devel/setup.bash and catkin_make?

Thx

EDIT: So far just not including the "build" file seems to do the trick - is this the best way?

2015-05-21 08:00:54 -0500 asked a question To be or not to be Catkin?

Hi,

I really need help sorting a rather large question.

As ROS continues are you going to be sticking with Catkin or moving to something else? And what would that something else be? I happen to like Catkin so I would prefer the former. But someone said to someone at some conference that you will be moving away from Catkin, which is why I can't upgrade all of our packages, in our project, to be Catkin (which is what I was really hoping to do).

Much appreciated.

2015-01-30 02:59:00 -0500 asked a question Launch into two machines only with access to one

Hi,

This is my setup:

Operator: Hydro Bot: Hydro Manipulator: Hydro

I am on Operator, I need to ssh into Bot and from there ssh into Manipulator, launch a script by cd'ing into its directory and running ./script_launch. Then exit Manipulator and launch node on Bot. Then exit Bot and launch script on Operator. I wrote a bash script that does this - but its not working so now I am looking at using a launch file.

i.e.

ssh bot
ssh Manipulator
cd /path/to/file
./script
exit Manipulator
launch node launch_file.launch
exit Bot
launch nodeOperator launch_fileOperator.launch

any help is much appreciated

or upgrade.. I found this error went away with hydro..

2014-06-02 08:24:53 -0500 answered a question EV3 not NTX

Hi - this is a great question - and one that I am trying to work the answer out for.. I found this: https://github.com/mindboards/ev3dev its a linux distro for the EV3 that should work if you have a microSD and follow the instructions - take a look at this error first though: https://github.com/mindboards/ev3dev/... - which helped - but I haven’t gotten past the boot screen yet, you may have more luck.. The next step for me would be then to get a wifi dongle working and see how I can send commands to the EV3 real time.. I was thinking of trying to install a light version of ROS on the SD card - but I am now sure if that is a good idea either.. Will definitely follow up as soon as I have anything more to offer.

2012-10-16 21:29:45 -0500 commented answer openni_launch not working in fuerte + ubuntu precise 12.04

Thanks - that works for me - but it still doesnt sort out the warnings encountered to correctly set up the yaml files (I will have to look further in to this) and there are times when I still have to kill all and reboot - not the most elegant of solutions hoping OpenNi sorts it out for Fuerte

2012-10-15 03:22:08 -0500 answered a question How to setup pointcloud_to_laserscan?

Thank you >> just as an update (and after a bit of head bashing) the final launch file is: (note the changes to the include launch file and the name of the nodelet required)

<launch> <include file="$(find openni_launch)/launch/openni.launch"/>

<node pkg="nodelet" type="nodelet" name="openni_manager" output="screen" respawn="true" args="manager"/>

<node pkg="nodelet" type="nodelet" name="pointcloud_throttle" args="load pointcloud_to_laserscan/CloudThrottle openni_manager"> <remap from="cloud_in" to="/camera/depth/points"/> <remap from="cloud_out" to="cloud_throttled"/> </node>

<node pkg="nodelet" type="nodelet" name="kinect_laser" args="load pointcloud_to_laserscan/CloudToScan openni_manager"> <remap from="cloud" to="cloud_throttled"/> </node> </launch>

Hi, thank you so much!! I just wanted to highlight below @Bart - for fuerte with precise you need to add the mods that are in that launch file i.e:

2012-10-11 03:54:16 -0500 answered a question openni_launch works only the first time

The only answer I found that worked for this was to run:

killall -s 9 XnSensorServer

before you rerun the openni_launch - this still does not solve all the other warnings but it does help not having to restart your entire system to get it running again..

aaaah! I have the same problem but there are no answers :( did you manage to sort it out?

2012-05-21 23:20:31 -0500 answered a question openkinnect : build error (Fuerte version)

Hi, I am having a similar problem - but it seams like the kinect openni drivers etc are already in the kinect package and that manually installing the drivers like you mention is over doing it - but how to get it running I dont know..
