Hello again 😃

I want to use Velodyne Lidar. The urdf file has it's tags. But rostopic echo /points command returns none. I changed parameters and tried but cant do it. How can I use 3d lidar?

Thanks for your interest

here is the warning

[ WARN] [1690287699.820079586, 2168.940000000]: Interactive marker 'robot_twist_marker' contains unnormalized quaternions. This warning will only be output once but may be true for others; enable DEBUG messages for ros.rviz.quaternions to see more details.

i can fix the warning to change top_plate.stl from gazebo husky stl files. but i couldnt fix the error

here is the error

sometimes its opening but there is no image or map or etc :( do you know why and how to fix.

Hello,

I want to use depth camera and suppose the intel_realsense.urdf.xacro file is for depth camera. But I cannot see topics for this and depth camera images. How can I do that?

OS: Ubuntu 20.04
ROS Version: Noetic

Best Regards

I am running melodic not noetic and every other dependency is working but this one. It is preventing me from running roslaunch and I just need the correct dependency.

Hey bro, I am facing error regarding the flir camera description installation.
I am using ros melodic and in that I am unable to install this description.

Hello Community,

I am studing autonomous path planning using move_base.launch node and yaml files in this repo. I wrote a slope detector code and coordinate code that takes the gps data from terminal and convert them utm and mappose. The command is here:

rostopic pub --once /move_base_simple/goal_fix sensor_msgs/NavSatFix "header: seq: 0 stamp: {secs: 0, nsecs: 0} frame_id: '' status: {status: 0, service: 0} latitude: 49.900712660524746 longitude: 8.900719770176472 altitude: -1.2020334709814404 position_covariance: [0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0]"

The problem is the robot goes everywhere in your clearpath_playpen.world and my terrain map. However, When I want to go far points behind the hill, the robot cannot exceed the obstacle and cannot change its path plan. How should I set the parameters? Do you have some suggestions for that problem?

I have successfully executed all 5 usages from Keyboard teleportation to Map-Based Navigation, however I am unable to launch the multi_husky_playpen.launch file as there is no multimaster_launch package in neither the src paths or local noetic files. Any suggestions how to proceed with creation of a fleet management system in playpen world using the tinker-twins repository?
