Hey, so i've been making a package for a competition and made a custom model for an arena in Blender exported the .dae file for working in with ROS Melodic + Gazebo 9.
But the model spawns successfully but has no link. The code for the .launch file, URDF file below.
.launch file
<launch>
<!-- these are the arguments you can pass this launch file, for example paused:=true -->
<arg name="paused" default="true"/>
<arg name="use_sim_time" default="true"/>
<arg name="gui" default="true"/>
<arg name="headless" default="false"/>
<arg name="debug" default="false"/>
<arg name="arena" default="$(find grid3)/src/urdf/arena1.urdf"/>
<arg name="extra_gazebo_args" default="--verbose"/>
<include file="$(find gazebo_ros)/launch/empty_world.launch">
<arg name="debug" value="$(arg debug)" />
<arg name="gui" value="$(arg gui)" />
<arg name="paused" value="$(arg paused)"/>
<arg name="use_sim_time" value="$(arg use_sim_time)"/>
<arg name="headless" value="$(arg headless)"/>
<arg name="extra_gazebo_args" value="$(arg extra_gazebo_args)"/>
</include>
<param name="arena_description" command="$(find xacro)/xacro $(arg arena)"/>
<node name="urdf_spawner" pkg="gazebo_ros" type="spawn_model"
args="-urdf -z 0.0 -model arena -param arena_description" respawn="false" output="screen" />
</launch>
URDF file:
<?xml version="1.0" ?>
<robot name="arena_one" xmlns:xacro="https://www.ros.org/wiki/xacro" >
<gazebo>
<static>true</static>
</gazebo>
<link name="base_link">
<visual name="visual">
<geometry>
<mesh filename="package://grid3/src/mesh/Arena_ps2.dae" scale="1 1 1"/>
</geometry>
<material>
<texture filename="package://grid3/src/mesh/Screenshot from 2021-07-30 15-50-19.png"/>
</material>
</visual>
<collision name="collision">
<geometry>
<mesh filename="package://grid3/src/mesh/Arena_ps2.dae" scale="1 1 1"/>
</geometry>
<surface>
<friction>
<ode>
<mu>1</mu>
<mu2>1</mu2>
<slip1>0</slip1>
<slip2>0</slip2>
</ode>
</friction>
</surface>
</collision>
</link>
</robot>
Roslaunch says that the model has spawned successfully but in gazebo it doesnt seems to have any link has no link : image.
its my first time working with models of my own, thanks for your help.
