2016-04-21 13:47:43 -0500 answered a question Is mrpt_ro_slam deprecated?

mrpt_ro_slam is now working for range only slam.

2016-03-02 14:51:49 -0500 answered a question how to create package in jade?

If you were referencing this tutorial, http://wiki.ros.org/ROS/Tutorials/Cre... , then you have to make sure you have 'catkin' selected, rather than 'rosbuild' (this option is located right below 'Next Tutorial: Building a ROS package').

2016-02-23 18:16:45 -0500 asked a question Is mrpt_ro_slam deprecated?

I would like to use the mrpt_slam package so that I can run mrpt_ro_slam (range only slam). It looks like the package ended at Hydro ( http://wiki.ros.org/mrpt_ro_slam ) and I have Indigo. Is the mrpt_navigation package the continuation of the mrpt_slam package? It is on Indigo and Jade ( http://wiki.ros.org/mrpt_navigation ) and contains mrpt_localization, but it is unclear to me if it has some version of range only slam.

Basically, my question is if there is a range only slam package that has not been deprecated?

Yes, in the end it was actually a value something slightly less than max that allowed for clearing.

To customize the filter take the LaserScanRangeFilter from laser_filters and modify the header file (range_filter.h) so that instead of filtered_scan.ranges[i] = quiet_NaN(), make it filtered_scan.ranges[i] = max_value; where max_value is within your laser range max.

Looks like there is access to the bag file here: http://answers.ros.org/question/21136...

The tutorial page has been updated.

2015-06-24 20:59:03 -0500 answered a question Apply Joint Effort to Gazebo Model

I think I found out from the Gazebo board that that service call did not use physics and so was not relevant to me. Instead I was advised to use a plugin so the ROS side of things would have to involve the plugin. Closing this out.

2015-04-06 15:47:18 -0500 asked a question "You don't have permission to access" laser.bag

Hello,

I was trying to follow the laser_pipeline tutorial: http://wiki.ros.org/laser_pipeline/Tu...

I saved the link for laser.bag (located here: http://vault.willowgarage.com/wgdata1... ) but it said that I didn't have permission to access it. From the bag file: "You don't have permission to access /wgdata1/vol1/wiki_docs/laser_pipeline/laser.bag on this server." Is this just an outdated link?

Thanks

Hello,

I found that when following the command "sudo apt-get install ros-hydro-ros-tutorials ros-hydro-geometry-tutorials rviz", I got an error. I resolved this by changing "rviz" to "ros-hydro-rviz". Is this the correct way to do this or should it be working with just "rviz"? http://wiki.ros.org/action/login/tf/T...

couldn't you also just separate into two launch files: 1st one launches world, 2nd one launches robot+sensor

is this question more suited for the Gazebo forum?

2014-08-28 20:22:46 -0500 asked a question Apply Joint Effort to Gazebo Model

Hello,

I am using Gazebo with ROS. I created a model in Gazebo that I was able to successfully send service calls to (to get a joint to spin for example). Specifically, I used the srv file gazebo_msgs/ApplyJointEffort (with a serviceClient node). What I'm trying to do now is get the nodes to be publisher/subscription-based to match another structure I am working with. Is it possible to create my own msg file based off of the gazebo_msgs/ApplyJointEffort srv in order to make a publisher node and still an effort on a joint? I tried doing just that and the publishing happens but there is no response to the model in gazebo. I'm obviously uncertain as to how the gazebo_ros package communication exactly works so any help would be appreciated.

Thank you

2014-07-01 20:11:14 -0500 asked a question Update to tutorial, ROS/Tutorials/Recording and playing back data

At the Recording and playing back data tutorial (I wasn't allowed to post the link because of low karma) in the section "Recording a subset of the data" the old form of command velocity is used and I just thought there should be a note reminding new users to change to the new form of command velocity. I am specifically referring to the following command line: $rosbag record -O subset /turtle1/command_velocity /turtle1/pose It should be noted that you can use cmd_vel instead of command_velocity.
