Collision issue

edit

So I have just got my custom robot going around the Kitchen, its running Hector Slam, Lidar etc. /odom is from the Hector not encoders, however it is working quiet well.

The only issue is the when I navigate it to a place, the collision seems to be a little out, it gets too close to an obstacle. I have the footprint set-up I have a URDF with a base_frame set-up (the robot is about 18cm square). In RVIZ I have ticked the collision box on the model. I want to make sure the robot does not get a x amount of cm to an object

obstacle_range: 2.5 
raytrace_range: 3.0 
footprint: [ [0.10, 0.10], [-0.10, 0.10], [-0.10, -0.10], [0.10, -0.10] ] 
inflation_radius: 0.05 


      <link name="base_frame">
        <visual>
          <geometry>
            <box size="0.18 0.18 0.07"/>
          </geometry>
          <origin rpy="0 0 0" xyz="0 0 0.085"/>
          <material name="white">
            <color rgba="1 1 1 1"/>
          </material>
        </visual>
        <collision>
          <geometry>
            <box size="0.18 0.18 0.07"/>
          </geometry>
        </collision>

I adjusted the values a little, below are some pictures before and afte crash Randomly, it worked fine the first and 3rd time
