2014-01-28 17:30:17 -0500 marked best answer rosjava groovy install help

Hey all

Am looking to install ROS java and have been going through the external documentation here http://docs.rosjava.googlecode.com/hg/rosjava_core/html/installing.html

However it is for older versions of ROS that do not use catkin. Is there anything different I need to do in order to correctly install ROSJava into my catkin workspace?

Also "rosws merge http://rosjava.googlecode.com/hg/.rosinstall" is giving me a 404 error and using the links from "https://github.com/rosjava/rosjava_core" are giving me a 406 Not acceptable error.

Any help from someone who has installed ROSJava on Groovy?

Cheers

SOLVED

Had to clean my update list on my ubunutu install, somehow it had become corrupted. Cleaning that up and attempting "sudo apt-get install ros-groovy-joystick-drivers" again worked perfectly fine

Hey

I am trying to install ROS joy for ROS Groovy

After saying yes to install the package it fails to fetch the files "Failed to fetch http:\... 404 not found error".

I am using "sudo apt-get install ros-groovy-joystick-drivers" to install.

Is their an updated wiki about how to install ROS joy on groovy that I have missed?

Thanks heaps

2014-01-28 17:27:44 -0500 marked best answer Single board PC for ROS

Hey

Which Single board computers are recommended/better suited for running ROS (Fuerte and Ubunutu 12.04 or other recommendation)?

This has been asked a few times before, but not recently as far as I could find anwyays, sorry if double up though.

My application will be running with a Hokuyo URG LIDAR (http://www.hokuyo-aut.jp/02sensor/07scanner/download/products/urg-04lx-ug01/) and using an Arduino to do all the motor/servo controls.

All low level control such as SLAM will done on board so will need to be capable of processing everything.

It will also be sending and receiving high level information from a main computer so will need to be network capable as well, we do currently have a Wireless modem on the robot itself so the SBC does not need built in wireless.

Cheers for any advice

2014-01-28 17:27:35 -0500 marked best answer rosserial Fuerte install help [Solved]

EDIT: Managed to download from source and install without issue. Had to restart as updates were preventing connections.

Hey

I am currently trying to install rosserial for ROS Fuerte, and I keep getting that rosserial can not be found.

From everything I have seen it should exist, however following instructions from http://www.ros.org/wiki/rosserial_arduino/Tutorials/Arduino%20IDE%20Setup do not seem to be working.

Trying to download from debs I get the following.

robot@robot:~$ sudo apt-get install ros-diamondback-rosserial

Reading package lists... Done Building dependency tree
Reading state information... Done E: Unable to locate package ros-diamondback-rosserial

Trying to install from source, I am new'ish to Ubunutu so this error I think is as simple as me missing something.

robot@robot:~$ hg clone https://kforge.ros.org/rosserial/hg rosserial abort: error: no host given

What steps am I missing to download rosserial correctly?

2013-09-15 16:24:47 -0500 answered a question How to run a different roscore in different robots?

Hey,

You will want to run a single roscore that both robots use. The instructions on running ROS multiple machines should be a good place to start looking into this: http://wiki.ros.org/ROS/Tutorials/MultipleMachines

It is very easy to do once you can get an ssh connection between the robots.

Hope that helps

2013-07-17 18:20:14 -0500 commented answer how does the odometry (imu+encoder) publish its data to gmapping?

Yes sorry Weiin is correct, Gmapping does not need it itself :D

2013-07-16 14:50:21 -0500 commented question rosserial_arduino: lost sync with device when handling interruptions

OK, one difference I can see.

Do you really want to set an interrupt on change? Rising would make more sense as you only want a interrupt when the hall effect goes high, not both rising and falling edges.

Other than that, can't see any problems sorry.

2013-07-16 14:44:04 -0500 commented question rosserial_arduino: lost sync with device when handling interruptions

Hey, I do exactly as you have described with my robot to get wheel speeds. Have not encountered this issue myself however. What version of ROS are you using?

I will look at my code and see if I spot anything overly different

2013-07-16 14:42:21 -0500 answered a question how does the odometry (imu+encoder) publish its data to gmapping?

Hey,

Basically as Weiin said the Gmapping link shows that Gmapping is subscribed to tf/tfMessage to get its odometer information.

You need to publish the odometer information as both a nav_msgs/Odometry and a tf/tfMessage. A good tutorial explaining this can be found here

As far as I am aware, you can use standard Python methods for getting input from the keyboard when making your program.

other potential bugs when it does start compiling for you, usually solved by setting JAVA_HOME, I ran into the same problem as this link and the second answer solved the issue for me

2013-05-28 12:05:03 -0500 answered a question rosjava installation

Hey,

First do not use rosws, that was what I was told. Install from source and run catkin_make.

ROSjava has been catkinized. Basically what I did to install was to download into my work space from source https://github.com/rosjava/rosjava_core

cd into my work_space and run "catkin_make". It then nicely compile everything for me. I did run into an error at one point but it has been resolved here https://github.com/rosjava/rosjava_core/issues/156

If catkin_make does not work, you can cd into ROSjava package and just run ./gradlew as well. Or at least I could about a month ago.

Hope that helps :D

Are you installing for ROS groovy?

will test that tomorrow, I know I can roscd in rosjava_core quite happily. The test_ros "pakcage" is stored within a subdirectory of rosjava_core. Would assume it would be able to see it, but will check tomorrow, cause you are probably right

2013-05-08 14:17:49 -0500 commented answer Pioneer3-dx - ROSARIA or p2os? rosws or catkin?

Hey, I am in the same boat as you Gershon, before I start on Derecks commands, what hiccoughs did you have? and how did you get around them? Edit: Further question, has the wiki been updated and can ROSaria now be smoothly installed based on the wiki?

2013-05-02 14:09:12 -0500 answered a question rosjava groovy install fail

Ok, found a solution however it is not a proper fix, although works.

First I found test_ros was not being generated inside "rosjava_core/rosjava_messages/build/generated-src".

Taking test_ros from a previous compilation of rosjava (different computer running fuerte), I placed this folder inside the generated-src folder.

Running ./gradlew or catkin_make, then ran a successful build.

This is not a proper fix, and I have put a issue under the git repo for rosjava, hopefully someone who knows the system a bit better than I do can solve it.

Feedback so far: When running either "catkin_make" or "./gradlew install" rosjava is unable to find rosjava_test package. I put a report on the git stie here https://github.com/rosjava/rosjava_core/issues/156

2013-04-30 15:02:31 -0500 asked a question rosjava groovy install fail

Hey

I have downloaded rosjava_core into "~/catkin_ws/src/rosjava_core".

I am using Java version: OpenJDK Runtime Environment (IcedTea6 1.12.3) (6b27-1.12.3-0ubuntu1~12.04.1) OpenJDK 64-Bit Server VM (build 20.0-b12, mixed mode)

Although trying with JDK 7 still produces the same error.

Installing rosjava in groovy after the catkin update and receiving an error when running catkin make from "~/catkin_ws"(see below for print out).

Error message in print out

19 errors :rosjava_test:compileJava FAILED

FAILURE: Build failed with an exception.

  • What went wrong: Execution failed for task ':rosjava_test:compileJava'.

    Compilation failed; see the compiler error output for details.

  • Try: Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output.

BUILD FAILED

Has anyone encountered this error in groovy or previous versions? Searching has found some results but no solution to the problem as far as I can find.

EDIT: After a bit more debugging it saying "Pakcage test_ros does not exist"
