ros noetic下报错

[chenzhengxi]

在ros noetic下跑，报这个错误
Failed to build tree: parent link [base_link] of joint [camera1_joint] not found. This is not valid according to the URDF spec. Every link you refer to from a joint needs to be explicitly defined in the robot description. To fix this problem you can either remove this joint [camera1_joint] from your urdf file, or add "" to your urdf file.

sorry, I haven't check its performance on ros noetic.

@chenzhengxi 把urdf文件夹下两个 .xacro'文件中所有的xacro宏调用改一下，这个错误就没了，也不用改几个地方。

1. robot_with_realsense.urdf.xacro
   第七行的<robot_body/> 改为 <xacro:robot_body/>
2. robot_body.urdf.xacro
   同理，这个文件中xacro宏调用部分也加上加上xacro：前缀就行了，例如：

        <xacro:wheel lr="right"  translateY="1" />
        <xacro:wheel lr="left"  translateY="-1" />
        <xacro:caster fb="front"  translateX="-1" />

   以及好几个inertial matrix的调用，例如<xacro:sphere_inertial_matrix m="${caster_mass}" r="${caster_radius}" />

@marquistj13 你好，我是在ubuntu20上运行这个代码，还遇到了这样的错误，请问你知道怎么解决吗

material用大写Red,White,Black, ImageFormat 用R8G8B8

请问noetic下跑通代码以后，有6个image的topic但是都没有数据，小车也控制不了是什么情况。。gazebo环境里压根就没有小车。。
