2014-01-28 17:22:34 -0500 marked best answer Text to speech voices

I see this has been asked in the past but I have not seen an answer that works. Text to speech uses a very slow hard to understand voice. I followed http://ubuntuforums.org/showthread.ph... and installed the enhanced Nitech HTS voices. I ran festival from the command line and can hear the new voices. i tried editing the festival usr/share/festival/festival.scm file and added (set! voice_default 'voice_nitech_us_rms_arctic_hts) but when I do that and then try to get it to speak form my python program I get no speech out whatsoever. If I comment out that line my python program works just with the nasty voice. I also added the festival.scm file to /etc (there was not one there) like mentioned in another answer but when I do that again my sound disappears. I also tried modifying voices.scm and changing KAL to don but that still does not help. I think I have tried everything mentioned here. Has anyone figured out how to fix this? I'm using diamondback on ubunto 10.10.

I've done the soundplay tutorial and can do text-to-speech from the command line, but can someone explain how to do it from inside a python program?

2014-01-28 17:22:31 -0500 marked best answer navigation tutorial dependencies

I have done the URDF tutorial and have a model of my robot. I also have a neato lidar sensor publishing data using http://www.ros.org/wiki/xv_11_laser_d... . Odometry is being published by the Serializer package.

My question is in the Navigation tutorial it says to do a "roscreate-pkg my_robot_name_2dnav move_base my_tf_configuration_dep my_odom_configuration_dep my_sensor_configuration_dep"

What do I put in for "my_tf_configuration_dep" "my_odom_configuration_dep" and "my_sensor_configuration_dep"

Thanks in advance

2014-01-28 17:22:30 -0500 marked best answer odometry Tutorial and Rviz

I'm working through the http://www.ros.org/wiki/navigation/Tu... tutorial. I have the code running so it is publishing odometry info. I have also done the URDF_tutorial so I have a model of my robot that I can see in Rviz. If I run both of these at the same time should I see the robot running around in circles in Rviz? Is it not that simple or does Rviz not work that way?

2014-01-28 17:22:23 -0500 marked best answer How much horsepower is needed to run the kinect stack

I have the kinect installed but RVIZ is really slow, a frame every few seconds I'm assuming it is my graphics card that is causing it.I have a Dell Inspiron 9400 and it has an ATI Mobility Radeon X1400. Any idea if this is good enough? Is there any way to spec a computer/video card combo or a way to test a computer? My pc is a dual core 1.8Mhz with 2 gigs of ram. That is close to the specs for the netbook that comes with the turtlebot. Could it be something else in my system causing the slowness. The CPU's are running at 98% when the kinect is running.

Thanks

2014-01-28 17:22:22 -0500 marked best answer installing XV-11 driver git error

I'm following the directions from here, http://www.ros.org/wiki/xv_11_laser_d... I installed Cturtle and then when I try to install the driver I get this.

linux$ rosinstall ~/cwru-ros-pkg /opt/ros/cturtle 'http://www.ros.org/wiki/xv_11_laser_driver/Tutorials/Running%20the%20XV-11%20Node?action=AttachFile&do=get&target=cwru-ros-pkg.rosinstall' rosinstall operating on /home/ringo/cwru-ros-pkg from specifications in rosinstall files /opt/ros/cturtle, http://www.ros.org/wiki/xv_11_laser_d... processing config_uri /opt/ros/cturtle ERROR: woah, unknown installation method git not installed, cannot create a git vcs client

So do I need to install GIT or is there another way?

2014-01-28 17:22:22 -0500 marked best answer error installing openni_kinnect

I'm using ubunto 10.10 and trying to install the kinect drivers. I got as far as sudo apt-get install ros-diamondback-openni-kinect hg clone https://kforge.ros.org/openni/drivers cd drivers make make install

but make install runs for a while then fails. Here are the last few linessudo cp -f ./openni/lib/.so /usr/lib/ sudo cp -f ./openni/lib/.xml /etc/primesense/ sudo cp -r ./openni/include/ni/* /usr/include/openni/ sudo cp -f ./openni/bin/ni* /usr/bin/ sudo /bin/bash ./CONTROL/openni_postinst postinst called with unknown argument `' make: * [install_openni] Error 1

how do I fix it? Thanks

2014-01-28 17:22:11 -0500 marked best answer How to display sonar readings in Rviz

I have a custom robot and have a URDF model of it set up in rviz. I have several Sonars and Sharp IR sensors mounted on it. I'm working my way toward using the navigation tools, how do I show my sensor readings in Rviz? Or am I heading in the wrong direction?
