[ERROR] [1636805101.138944786]: Failed to build tree: child link [front_camera] of joint [front_camera_bracket_joint] not found about robomaster-simulator HOT 5 OPEN

Hi,
It is not tested in ROS Noetic version. You can go through the URDF files to fix this problem. I think there is something updated in ROS Noetic when parsing URDF files.

It is appreciated to fix this problem and create a pull requests.

Thanks for your feedback. After googling around, I find that it is because Noetic forbids the lack of namespace in xacro, as in this question. I successfully solve this problem after adding xacro: to every tag that lacks it.

However, another problem pops up, which shows the error message

E1114 14:51:45.012620 185069 localization_node.cpp:279] Couldn't transform from center_laserto /jackal3/base_link

I notice that this problem may lie in the roborts package. Could you please give some instructions on how to solve this problem?

Just a following up comment, it seems that the cause of the above problem is that the center_lazer or scan is somehow broken. Still, I have no clue on how to solve it.

Hi,
This may be related to the Lidar sensor. Maybe the link or joint's name is wrong due to the difference of parse xarco file in Noetic.

Hi @dongmingli-Ben , do you have the code adapted to work with ROS Noetic? Can I contact you to share it?
