Did you find a fix for this? This file has some related code. I am curious if there is an easier route.

I am thinking of buying the parrot mini drone to do some flight by sending twist messages from ROS. I want to know if someone has a working package.

I am converting laser Scan points from laser frame to map frame(occupancy grid).The tf between them changes as the robot moves so I need to listen to TF every time the laser callback is called. But the tf doesn't get called every time.It is only listened to once.the code is here. the waitforTransform doesnt get called at all.

2016-02-12 16:02:05 -0500 marked best answer How to create OccupancyGrid from Laser scan data and Pose (odometry)?

I am working on a laser scan matching algorithm and I have got the pose of the robot during laser scans. How do I generate a map with this data? I do not want to use gmapping. I just want to use laser and pose data and create map_server topic to visualize in rviz.I figured out that occupancy grid has to be generated and it would be published as /map but there is no tutorial as to how to generate a occupancy grid.

It works! Thanks.

Am I missing something or is its a work in progress? If its a work in progress I could try to fix this and push the fix.

Thanks, but I get this error: ROS get_physics_properties service call does not yet support physics engine [dart].

2016-01-26 15:33:21 -0500 asked a question How to start gazebo_ros gazebo with DART Physics engine?

I am trying to spawn a manipulator with urdf in gazebo and control using ros_control. How do I set the physics engine to be dart? I can get gazebo to run on its own by running: gazebo -e dart. How would I do the same with rosrun gazebo_ros gazebo?

2015-10-31 14:01:10 -0500 marked best answer How to publish transform from odom to base_link?

I am running a p3at in a gazebo with ros plugins. I need to subscribe to the odometry pose and update broadcast the tf between odom and base_link.How do I do it? Should I define a "odom" link in the .xacro file used for simulation? What about the joint type?

2015-09-11 15:20:09 -0500 marked best answer What are the current challenges in Mobile robotics?

I was working on a slam algorithm but found there was already a very efficient one(hector_slam) so stopped that work. I am out of problems to work on. I want to work on some problem but could not know where to start.

Did you figure out a way to deliver noisy data in Gazebo?
