I want to test a lot of topics with hztest ros.org/wiki/rostest/Nodes (no Karma no Link) Since all tests are launched in their own environment, it takes more than one hour to complete the testing, and nobody can use the robot. Because of that, I created a modified hztests to check all given topics in one bringup. But when I check more than about 6 topics the time limit is hit and the test fails:

File "/opt/ros/electric/stacks/ros_comm/tools/roslaunch/src/roslaunch/launch.py", line 669, in run_test raise RLTestTimeoutException("test max time allotted")

I successfully changed line 664: timeout_t= time.time()+test.time_limit to timeout_t= time.time()+1000.0

But is there a way to change the time_limit without manipluating ros_comm?

I tried 'rostest mypckg mytest --bare-limit=1000' and also setting a parameter time_limit on the parameter server, but both without success.

Very Old, sorry. but is there a filter for that purpose?

@mdtobi How far are you? can I see it somewhere? Keeping the NXT up-to-date sounds great. But, as already said, I have Exams and also regular work, so don't rely on me if it's for a Thesis. maybe we should start a SIG as IsaacSaito suggested in the other discussion

which lib ?

I did not look at the issues, my nxt-python version problem is also a Issue(15) there. It should work on the RPi. I only modified sensor car for my needs. Tell me if it works, or what your errors are.

@boog I don’t have a compass, also no Gyro IR or Color for further Testing :-( You could try to build your compass like the AccelerometerSensor(DigitalSensor) and by looking in a newer version of nxt-python. If it works, Send me a Pull Request plz

I will add my repo to the wiki soon. As my modifications where very minor, I dont think we a need a SIG. I started a related Question here: http://answers.ros.org/question/67831/is-there-a-newer-nxt_ros-stack-using-nxt-python-222-instead-of-120-on-raspberry-pi/

same here http://answers.ros.org/question/52836/lego-nxt-ros-working-on-groovy-galapagos/?comment=69874#comment-69874 never heard of ev3

same question dont know osx http://answers.ros.org/question/52836/lego-nxt-ros-working-on-groovy-galapagos/?comment=69874#comment-69874

I want to write a ROS Service that receives a Question and then shows a Qt Pop-up Dialog with the Question and a yes or no Button. The service should return the Answer as a Boolean. I have it with wx but since it is depreciated in ROS, I want to use Qt now. This is how it looked like with wx:

    rospy.init_node('dialog_server')
    s = rospy.Service('dialog', Dialog, self.handle_dialog)
    rospy.spin()
    def handle_dialog(self, req):
        ex = wx.App()
        dial = wx.MessageDialog(None, req.message, 'Question',
                        wx.YES_NO | wx.ICON_QUESTION)
        ret = dial.ShowModal()
        if ret == wx.ID_YES:
                answer = True
        else:
                answer = False
        return DialogResponse(answer)

I tried simply replacing wx with the equivalent qt (like wx.MessageDialog -> QtGui.QMessageBox.question) but it's not working because ros is another Thread. Error: "It is not safe to use pixmaps outside the GUI thread". I am not familiar with Qt, rqt python_qt_binding and plug-ins at all.

What do I need to achieve this? Do I have to use Slots and Signals between GUI and ROS, or even write it as a plug-in? How should it look like?

Since I would like to have the same Performance of the Linefollwer.rxe for teleop, I will start porting the nxt-python 2.2.2 to nxt_ros (based on 1.2.0) to have the complete MotorControl, and also setting the I2C Bus faster on the NXT. But don,t have time till mid of October for doing this. :-(

I added a execute "Sensor" to nxt_ros, to Start a NXT .rxe Program configured by the robot.yaml.

Old, but just saw it. Here I modified NXT for Groovy

https://github.com/maxsieber

I have a Raspberry Pi running ROS Groovy on a Lego NXT with a Webcam and Wifi.

Youtube: Pictures and complete Visualization.

The nxt_ros package is using the old nxt-python 1.2.0 and the performance of the Motors is good enough for teleop, but not for controlling. Therefore, I rewrote my controller: linefollower in NXC, and I am starting the .rxe Machinecode with ROS directly on the NXT.

Then I found a MotorControl for NXT, and that it is already included in the new nxt-python 2.2.2 version.

Before rewriting, the complete nxt_ros Package from nxt-python 1.2.0 to 2.2.2, does anyone knows, if this already exists somewhere?

Or maybe someone has experience with the new nxt-pythons 2.2.2 Motor-sync, and ideas for a new nxt base controller?

The parameter is time-limit not time_limit. So it's <test test-name="foo" pkg="foo" type="foo" name="foo" time-limit="1000.0"/>
