Subject: customizing the navigation stack
Hey all,
I have a rookie question.. I have a C-Turtle installation (installed with the "sudo apt-get install ros-cturtle-base" command) on a Ubuntu 10.04 machine and want to make some customizations to the ROS navigation stack. How do I proceed? A "rosmake" does not build this stack with the changes that I made to "move_base.cpp", probably due to the presence of "ROS_NOBUILD"? I am quite not sure about the next steps...
Please suggest.
Thanks and regards,
Debjyoti Bera.

Thanks Sachin,
I commented that out since I didn't know what value to set here. I guess
50.0 is a little too pessimistic...;-)
Also, I opened a ticket:
https://code.ros.org/trac/ros-pkg/ticket/4787

Felix

Hello Rodrigo,
I've been working with Kinect for sometime so forgot about the SR4000,
Anyways, i run the following
roslaunch swissranger_camera sr_usb.launch
and I get
[ INFO] [1297720701.371263065]: [SwissRanger device::open] Number of images
available: 3
[ INFO] [1297720701.371430408]: [] Connected to device with ID: 3D-SR4000
[ INFO] [1297720701.371476069]: [] libmesasr version: 1.0.14.653
Then I run rosrun rviz rviz, then changing some settings gives me the
PointCloud data and intensity image.
Thank you. That was helpful.
Best,
CV

Hi everyone,
Do you know any ros-package including an omni-wheel urdf? Or does anyone
happen to design an omniwheel in urdf? I just don't want to re-invent the
wheel :)
By the way, what I mean by omni-wheel is the one having a main wheel and
several roller wheels -mostly perpendicularly aligned-. Like the ones on the
robotino platform. I don't prefer using two motors for each wheel that can
imitate an omniwheel (=omni-drive) or changing the friction properties of
the surfaces in gazebo. These are some of the tricks that I'm aware of.
Thanks...

Hey Joe-
I recently moved turtle_teleop_key from the turtle_teleop package to
turtlesim which is probably the problem you're seeing.. you found the
correct solution, the debs were just out of date.

So I have been working on using IRI's segway library to implement a segway
driver for ROS, and I have run into a situation where I don't know how to
proceed.
IRI is setting up a port of their stuff for ROS, so at this point it is more
educational for me.
So, the IRI segway library relies on some of their other libraries.
My ROS Node depends on iri_segway_rmp200.
iri_segway_rmp200 depends on iricomms and iriutils.
iricomms depends on iriutils.
All of the IRI stuff is in SVN and is LGPL licensed, my stuff can be
considered MIT. They are setup to build dynamically linked libraries (.so
on linux and .dylib on osx).
The way I see it there are a few ways to approach this setup in ROS: (Maybe
there is a 4th, correct setup)
1. Put a script in rosdep.yaml to (svn co; make; sudo make install) each
of the libraries from IRI.
- This is good because the libraries are installed and no further
configuration is required, but requires root access
- Also, they install Find<lib>.cmake files in the cmake shared Modules
folder, which is nice
2. Create a ROS pkg for each library and use rosmake to build them, using
the svn_checkout.mk make script and patches to build and install them to
the pkg dir
- This is nice because the libraries are contained in the ros pkg
- But, you need to export cpp flags to include and link directories
- How do you handle runtime dynamic linking?
3. Download/Distribute and build the libraries in your ROS pkg and
statically link your node to the libraries
- Doesn't allow multiple nodes to link to a single source for the
libraries (build the libs for each node that uses them)
So here are my questions:
1. What is the preferred method of build architecture?
2. How do you handle dynamic linking at runtime? (the .so file is in
package A, and how does a binary in package B find it at runtime?)
3. How can you handle installing and referencing Find<lib>.cmake files
that libraries have? (use manifext.xml's <depend .../> instead, is my guess)
4. What if any licensing concerns are there? (patches and static linking,
etc)
Sorry if some of these questions are silly, I am still learning these more
complicated build systems (rosmake/cmake).
Thanks,

The documentation:

I would use pkg-config to get the build flags for Player. Assuming
that you're trying to build a client program against libplayerc++, do
something like:
include(FindPkgConfig)
pkg_check_modules(PLAYERCPP REQUIRED playerc++)
include_directories(${PLAYERCPP_INCLUDE_DIRS})
link_directories(${PLAYERCPP_LIBRARY_DIRS})
# Assuming that you're building an executable named foo
target_link_libraries(foo ${PLAYERCPP_LIBRARIES})
Note that you may have to add /usr/local/lib/pkgconfig to your PKG_CONFIG_PATH.

hi William,
Thanks for the patch! Can you put it in a ticket, so we don't lose track of it?

We're still in an exploratory phase as the project really only started
in late December. We do have a prototype infrastructure up and we
plan on iterating quickly using our "turtle bots" (Create + Kinect
platform).
We're open to collaboration, especially to enable other's to drive
their own priorities. The project page defines some of the basic
infrastructure elements, though there is further breakdown necessary
on the ROS infrastructure side, e.g. the wifi comm issues, etc...

The filter is active, which means that at some point one or more of
your sensors were active too. The robot pose ekf automatically enables
sensors when new data is received, and disables them when not data is
received in a time interval specified by the "sensor_timeout"
parameter. I think your sensors are getting activated and deactivated
all the time. You should get lots of useful information in rxconsole,
just try to run the robot pose ekf with rxconsole on.
Hope this helps,
Wim

Hello, everyone!
My video card is ATI radeon 4350, and the driver is working very well.
When I "launch gazebo_worlds empty_world.launch" the problem come out. There
are not error even warning. The world display area of gazebo is flickering.
So what is the problem and how can I fix it?
Thanks for your time!

Hi Shujun,
This is a common problem when running compiz. Try turning it off (on
Ubuntu: System -> Preferences -> Appearance -> Visual Effects ->
None). Others have recommended running "unset
LIBGL_ALWAYS_INDIRECT" before starting rviz, but I haven't tested this.
Hope this helps,

Thanks for the advice.
I tried to edit the Move_base.launch by replacing this statement from
<node name="map_server" pkg="map_server" type="map_server" args="$(find
my_2dnav)/map/map.yaml"/>
to
<node name="slam_gmapping" pkg="gmapping" type="slam_gmapping"/>
The program works very well initally but over time the system just crash.
I was wondering whether it's because of the laptop limitation ?
My current laptop spec is
core2 Duo with 2G ram and 128mb dedicated graphic card
with thanks,
Zhiping

Hey
Yesterday I figured out how to use target_link_libraries to add libraries,
but only one library at the time. A great thanks to Brian's CMake style
approach, just what I seeked, also thanks to Rich for the links, nice with
additional information of the use of CMake.

Cool, that's a nice overview page that I haven't seen before!
In fact, I was just looking for diamondback instructions yesterday to
find the recommended .deb variants and couldn't find it on the default
installation instructions (http://www.ros.org/wiki/ROS/Installation).
Maybe it's time to put a cturtle / diamondback switch there, as it
reached RC1 now?

Hi,
I setup a pair of prosilica camera, in mode 640x480 in two exposure rates 5 and 0.5 ,
When I subscribe to their topics by either "rostopic hz /stereo/left/image_rect_color" or "rostopic hz /stereo/left/image_raw"
In exposure rate 0.5, receive all messages without missing any and then it repeats again
In exposure rate 5, receive just 1 message and miss other 4 messages then it repeats again
I tried this in different rates and found out that I just can receive two messages (one left and one right) per second (or per ROS refresh rate), and any more messages would be missed by ROS.
The other point is that when I run stereo_image_proc it crashes as soon as starting to subscribe to it by either stereo_view or face_detector.
Anyone can help, please?
Reza,

.
there are 55 packages need to be installed, with one falls.
But when I installed it in my desktop computer a few days ago, only 54
packages is needed, and it is correctly installed.
I find that eigen package caused the error. I don't know how to deal with
it.

After upgrading to Debian 6.0 the rosinstall script works fine.
The new problem is that nothing would compile: "gcc fails to compile
simple program"
gcc was linked to gcc-4.3 so I had to do a rm /usr/bin/gcc and ln -s /
usr/bin/gcc-4.3 /usr/bin/gcc
Is there a more correct way of doing this?
Now things seem to be moving along.
This happened with both cturtle and diamondback by the way.

Hi,
Been a while since I used the asctec_autopilot node for communication
with the Pelican. I build the master branch and tried to launch it,
but somehow communication is not setup properly - it gives me some
error about 'insufficient data' when I try to read from the Pelican. I
switched back to the code I was working on last year (somewhere mid
august) which works fine (/origin/sbellens).
Checking the diff I see a lot of the low-level communication commands
have been rewritten and header fields are added to the ROS messages.
Can someone confirm whether the current code works with the Pelican
helicopter? Do I have to add something in my client code to get
up-to-date? I'm still using the XBee communication interface.
regards,
Steven

Correction, it was initially linked to gcc 4.4.
Also, the Debian Squeeze dependencies for boost and log4cxx should be
set to libboost1.42-all-dev liblog4cxx10-dev

Hello,
i want to convert PointCloud to LaserScan.
I have a Topic wich publishs point cloud.
if i try to make a map like this:
rosrun gmapping slam_gmapping scan:=point_cloud
i become a warning:
[WARN] 1297772305.065463: Could not process inbound connection: topic types do not match: [sensor_msgs/LaserScan] vs. [sensor_msgs/PointCloud]{'topic': '/point_cloud', 'tcp_nodelay': '0', 'md5sum': '90c7ef2dc6895d81024acba2ac42f369', 'type': 'sensor_msgs/LaserScan', 'callerid': '/slam_gmapping'}
So now i want convert pointcloud to laserscan.
Or if there is another way to make a map, with pointcloud?

Hi,
I think you can use this to convert from pointcloud to laserscan

I agree with boost,
I don't know what is stated for log4cxx but what you suggest seems correct.
I'll post a patch for it tonight

It's maybe a noobish question but do I need to do something special to
switch from a Beta installation to RC1 ?
I tried a rosinstall ~/ros and it didn't seem to have changed anything

Hi,
I am new to ROS.
I have a 4 camera stereo set using 4 synchronized cameras that are not
supported by ROS.
This is not unlike what PR2 uses.
I would like to use these camera with ROS.
What is the best way to do this?
1. Do I need to write my own "driver"? That is code that interfaces with
the camera APIs and publishes to ROS?
2. In that case, what do I publish? Do I give only raw image output or is
there a way to publish a stereo pair?
3. Are there any examples for how to do this, e.g. from some other stereo
cameras?
4. What is the easiest way to do this? As I said I am new to ROS.
Thanks,
Adi

Hello Wouter,
since nobody picked up on your email, I'll try to answer it, although
there are probably more qualified people on this list.
I'm not quite clear what you are planning to do. I'll assume that you
have some kind of gripper mounted on your Delta Robot, and that you
want to be able to grasp arbitrary objects in an unstructured
environment while avoiding collisions with other objects.
The tutorial you mentioned assumes the following:
- you have some kind of sensor that gives you a 3D point cloud of the
environment (a tilting laser scanner, a Kinect, ...)
- you have an URDF description of the robot
After you have implemented all the stuff in the tutorial, the typical
workflow is the following:
- you send a joint goal (vector of desired joint positions) or position
goal (in cartesian space) to move_arm
- move_arm will call a motion planner, such as ompl, to plan a
joint trajectory that will bring your end effector to the desired goal
- the resulting trajectory will be smoothed using splines
- the smoothed trajectory will be sent to the
joint_trajectory_action_controller that you have to implement, to be
executed on the robot.
During all those steps, the information from your 3D sensor will be
used to check the environment to make sure that the final trajectory
will not collide with any objects in the environment (or lead to
self-collisions, but that will probably not be a problem for a Delta
Robot).
Move_arm is commonly used to bring your end effector to a position near
the object to be grasped. Next, you will have to get the grasping
pipeline [1] going to actually plan and execute a grasp.
Arm navigation was designed for use with a 6+ degree of freedom
robotic arm, and I'm not sure how well it works for a 3 DoF Delta Robot.
Perhaps somebody else could chime in on that.
Regarding where to start: I would recommend developing the code for
communication with your controller first. Better post a separate
question for opinions on how to do that. Keep in mind that in the end,
you want to pass in joint trajectories [2], and the joints should move
along this trajectory. Before getting started on all the motion
planning stuff, you can just generate a simple joint trajectory, for
example using sin(t), to debug and test your code.
In parallel, you can develop an URDF model of your robot [3]. One
problem I can imagine you will run into is that a Delta Robot is a
3 DoF closed kinematic chain consisting of 9 joints, and I am not sure
how well URDF can represent this at the moment; perhaps OpenRave can
handle these things better [4].
Best wishes,
Martin

Hi everyone,
I've finished the first draft on the Roomba page
http://www.ros.org/wiki/Robots/Roomba
It still needs some stuff, I'll add some more content during the next days.
Thanks for the heads up on the URDF Jeff, I'll most certainly use that!

Look at the launch files, its fairly simple to use. My only problem with it
is that having a point cloud can generate multiple laser scans (I have one
from a kinect for example) but this stack only supports one. I'm working on
one for my own purposes at this point, I will post it to github or something
when I am done.

Hi Adi,
What type of camera's do you use? We just included a patch in
camera_drivers to allow for synchronized use of
prosilica_cameras. My idea is also to expand my implementation to
allow for a 'stereo' setup with multiple camera's.
My setup typically has a larger baseline than PR2's.

I'm not at the lab at the moment, but as far as I know the master branch
should be working. You may also want to look at the experimental branch
which is getting closer to release. Also, I should have debian packages
out by Friday.
One thing to watch out for with the XBee interface is that the maximum
polling frequency is lower.

Dear Friend,
I hope and pray that I have the right person who will help me. I have interest of investing in your country as such I am making contact with you for assistance.
Before the war in my country (Iraq) I deposited some funds with a Bank for safe keeping which I am looking for a partner that will help me retrieve the funds from the Bank as I cannot travel out at the moment because of my present predicaments /conditions which I will explain to you as we progress. My name is Raheem Mubarak Ali from Iraq. Late Saddam Hussein totally brought destruction / Hell and political instability to our great country and everything is practically difficult now. Please if you accept this offer of assistance you are required to give me your Name, age, occupation, country and address.
I will send to you detailed information of this business if you indicate your seriousness to do the business, and also enclosing your telephone fax numbers. I promise you that this deal is valid, real and risk free. What I now need from you are as follows:
1. You should make contact with the Bank to secure the funds as I will be entrusting the business into your care.
2. You will be entitled to 30% of the total sum involved for your assistance.
3. As soon as you have the funds in your custody, we will enter a new arrangement on which sector you will invest my share of the funds in on my behalf to generate enough money for the up keep of my family in your country.
4. This project is 100% risk free, but you must keep it very secret and confidential with strong assurance that you will never let me down at all.
Please note that my aim to transfer the funds to you for investment is because I want my wife and 4 kids to join you and stay under your care, hope my family will find comfort, peace and happiness once again in your country.
I want to clear you about this, the funds is not from drug deal, its not from arms deals, its not government money and its not for any terrorist or illegal activity, why I am emphasizing on the confidentiality is because I don't want you to be bordered over above issues. Can you help me? Are you trustworthy? Are you capable of handling this money? Can we partner? If yes, please contact me immediately so that I will give you more details about the funds. All you need to do is to claim this money from the Company for our mutual benefits. For your assistance, you will be entitled to 30% of the total sum. You are also obliged to help/advise on the proper and most convenient way of investing this money in your country, hopefully, You will consider this request and respond positively.
I expect your prompt reply and let our communication be by email as it is the safest means of communication for now because I suspect telephone lines in Iraq been connected to the US Telecommunication Network for monitoring.
Regards,
Raheem Mubarak Ali.

That depends on what kind of cameras they are.

Yes.

There are standard ROS ways to publish stereo data.
http://www.ros.org/wiki/stereo_image_proc
http://www.ros.org/wiki/camera_calibration
http://www.ros.org/wiki/image_pipeline

The extra ROS wrapping for publishing camera data does not involve
much additional code, but does require a basic understanding of the
image pipeline. So, study the interfaces and look at examples of other
drivers, then ask more questions.

What do you mean that you get one message out of 5? Do you mean that
you see messages on the image_raw topic but not on the output of
stereo_image_proc, or does it mean that the images aren't even
arriving on the image_raw topic?
In any case, resource limitations of various types can cause a lower
than expected frame rate:
- CPU overload can cause frames to be dropped.
- Insufficient lighting can cause the exposure time to be long, and
the frame rate to be lower than requested.
- Insufficient network bandwidth can limit how many frames get over
the network (seems unlikely in your case).
Hard to say more without knowing more about your system.

I'm trying to install vslam with cturtle via the instructions here:
http://www.ros.org/wiki/vslam
and I ran into a few problems.
First, the unstable version of pcl is not compiling. text here:
http://people.csail.mit.edu/garratt/makelogs/pclmakelog.txt
Anyway, I switched to using
tags/perception_pcl-0.8.0/
Then sba fails, also complaining about eigen.
So I switched it to tags/vslam-0.2.2
and it compiles.
It seems as though we need to start creating cturtle/diamondback install
pages, which give the appropriately tagged versions.
I just had to do this for my packages:
http://www.ros.org/wiki/mit-ros-pkg/KinectDemos#Software_Setup
I even nabbed the appropriate pictures...

Hi Koen,
These are the cameras I have VRMagic Multisensor Intelligent
Cameras<http://www.vrmagic.com/imaging/cameras-framegrabber/multi-sensor-cameras/>
.
How would you suggest I proceed?
Thanks,
Adi

Thank you, I will.
BTW, is there a "mock" camera module, that I can feed AVIs or other video to
simulate a camera?
This will help me with debugging and also with understanding the whole
pipeline.
Thanks,
Adi

Hi Adi,
my group is working on a driver. Last time I checked (2 days ago ;) )
it was possible to retrieve images from 2 sensors (we only have a
two-sensor system) and perform stereo calibration for the first time.
It's really very basic at this point, but I'll look into getting it
into some publicly accessible Repo.
regards,
Stefan

Hi Stefan,
You mean you are working on a driver for the VRMagic camera?
If so that's great. I'd be grateful if you let me know when it's ready.
I'll be happy to run tests for debugging if you like.
Warm regards,
Adi

Hi Ugo,
To see what the current state of the environment server is you have to run
an another program in the planning environment package. Here's the contents
of the launch file in
planning_environment/launch/display_planner_collision_model.launch:
<launch>
<node pkg="planning_environment"
name="display_planner_collision_model_environment_server"
type="display_planner_collision_model" respawn="false" output="screen">
<param name="skip_collision_map" type="bool" value="false" />
<param name="prefix" type="string" value="/environment_server" />
</node>
</launch>
This node calls services in the environment_server and broadcasts markers
with the objects. You should see a marker topic after you launch this, and
a collision map topic showing the state of the collision map the environment
server uses.
Are you sure you are processing the kinect data through the appropriate set
of self filters? You need to be filtering the robot and the attached objects
out of the point cloud in order for the grasping pipeline to function. I'm
attaching a couple very experimental launch files that should process the
kinect data through the required pipeline to produce robot-free collision
maps.
Let me know how it goes.
-Gil
