Adding revolute joint makes the wheels disappear
Hello,
I am trying to create a 2 wheel mobile robot using xacro file.. I followed the tutorials when using SDF and I convert it to xacro and I have two links for the wheels and two joints of type revolute. when I add the revolute joints and I run the launch file I cant see the wheels on gazebo .. I have the following tags for the joints ?? is there any thing wrong ?? also, is it the right way to have a revolute joints of 2 wheels robot ??
<joint type="revolute" name="left_wheel_hinge">
<origin xyz="0 -0.18 -0.03" rpy="0 1.5707 1.5707"/>
<child link="left_wheel"></child>
<parent link="base_link"></parent>
<axis xyz="0 1 0"/>
<limit effort="0.0" lower="0.0" upper="0.0" velocity="0.0"/>
</joint>
<joint type="revolute" name="right_wheel_hinge">
<origin xyz="0 0.18 -0.03" rpy="0 1.5707 1.5707"/>
<parent link="base_link"></parent>
<child link="right_wheel"></child>
<axis xyz="0 1 0"/>
<limit effort="0.0" lower="0.0" upper="0.0" velocity="0.0"/>
</joint>
