2019-10-25 03:37:12 -0500 | marked best answer | no timestamps when publishing for fixed joints robot_state_publisher Hi guys, I have the following problem: I wrote a launch file which launches my differential drive robot with 2 lidar sensors in gazebo and rviz. The odometry for my robot comes from the differential drive plugin and the transforms for my robot come from the nodes "robot_sate_publisher" and "joint_state_publisher". I have 3 fixed joints "base_link" to "chassis" and "chassis" to each of the lidars and 2 continuous joints "chassis" to "wheel" for each wheel. Now when I look at the rqt_tree I see that the transforms for all the fixed joints, there is no time_stamp for the transforms and also I cannot choose to see the Pointcloud data in the odom frame since rviz tells me that the message was removed, because it is too old. My question: do I have to code now a separate node which broadcasts all these transforms with a time stamp? I thought that the robot_state_publisher and joint_state_publisher nodes that I launch in the launch-file are exactly for that: to publish all the transforms (whole transform tree) of my robot. But I only get stamped messages for the chassis to wheel tranforms and odom to base_footprint transforms but not for the fixed joints. (I already tried with static_transform nodes to publish static transforms, but still no timestamp) Launch File: Thank you very much in advance! |

2019-10-17 07:08:43 -0500 | marked best answer | joint state publisher dies, cannot attach wheels with continuous joint Hi, I am currently trying to create a simple differential drive robot model with 2 wheels and 2 caster wheels, but I cannot attach the wheels to the chassis with continuous/revolute joints and I do not get the transforms of course, but I can connect them with fixed joints and I also get the correct transforms with the fixed joints. I am using ros melodic with Ubuntu 18.04.3 LTS on VM 6.0.12
