@2745914991 在从ros1平台迁移到ros2平台，然后将机器人模型导入gazebo时失败，gazebo无响应中说：

出现了重复名字的link，建议仔细检查下urdf

@小鱼感谢鱼哥回复，我已经仔细检查了我的urdf文件，并没有出现重复名字的link

此外我输入指令

check_urdf /home/leolanqin/catkin_ws_ros2/src/robot_description/urdf/robot_description.urdf

终端显示

robot name is: robot_description
---------- Successfully Parsed XML ---------------

        child(4):  base_laser_link

        child(6):  right_wheel_link

也没有问题，实在不知道问题出在哪里

@leolanqin 在从ros1平台迁移到ros2平台，然后将机器人模型导入gazebo时失败，gazebo无响应中说：
