How to simulate Temperature and create an office room

Question

1)i want to create a room from a greyscale image, i have seen two methods using gazebo: with the tag but with this i can't apply a texture to the side of the wall, but only from the hight, and with the tag but this doesn't work, and i don't undertand why, the sdf file is:

<?xml version="1.0" ?>

model://sun 0 0 20 model://ground_plane 0 0 1 0 0 0 2 2 2 2 2 2 1 0 0 1 1 0 0 1

<!-- -->
<model name="image_map">
  <static>true</static>
  <pose> 0 0 0 0 0 0</pose>
  <link name="link">
    <collision name="collision">
      <geometry>
    <image>
                <uri>file://media/materials/textures/room4.jpg</uri>
                <scale>20</scale>
        <threshold>200</threshold>                  
        <height>3</height>
        <granularity>1</granularity>
        </image>
      </geometry>
    </collision>

    <visual name="visual"> 
      <geometry>
        <image>
                <uri>file://media/materials/textures/room4.jpg</uri>
                <scale>20</scale>
        <threshold>200</threshold>                  
        <height>3</height>
        <granularity>1</granularity>
        </image> 
      </geometry>
    </visual>

  </link>
</model>

2. i want to simulate a physics element like the temperature in environment and to relevate it with a sensor, is this thing possible to do? are there any projects available?

thank you for your answer

Answer 1

The geometry model is broken in Gazebo, see this issue.

Temperature is currently no implemented in Gazebo. The easiest solution is to write a WorldPlugin that outputs temperature data. Example world plugin. Every update cycle, your world plugin could get the position of you robot, and then output a temperature value to a topic.
