## Assumption

- You are running ROS Melodic
- You are running Gazebo Version 9
- You are on a Linux machine (e.g. Ubuntu18.04)

## Moving Actor Only

Follow the sdf format below to add an actor in Gazebo world.  
Note that animated models have no collision model nor does it interact with gravity.  
This example is taken from [servicesim_competition](https://github.com/osrf/servicesim/blob/master/servicesim_competition/worlds/follow_actor_demo.world#L32).  
For more detail please refer to official Gazebo [page](http://gazebosim.org/tutorials?tut=actor&cat=build_robot).

## Actor with Plugins

Follow the sdf format below to animate an actor with plugins in Gazebo world.  
The focus of the tutorial will be placed on human actors, therefore, I will only explain plugins that are related to human actors.  
All the plugins can be found in [service_competition](https://github.com/osrf/servicesim/tree/master/servicesim_competition).  
For AutoActorPlugin, it can be found [here](https://github.com/BruceChanJianLe/gazebo-plugin-autonomous-actor).

### Attach Collision Model to Actor (Plugin)

Follow the sdf format below to add the related plugin to your actor.  
This plugin will add a static model to your moving actor.  
Here a box collision model is attached to the human actor.

```xml

<model name="human_94763_collision_model">
  <pose>0 0 -100 0 0 0</pose>
  <static>true</static>
  <link name="link">
    <collision name="link">
      <pose>0 -0.18 0.05 0 -1.5707963267948966 0</pose>
      <geometry>
        <box>
          <size>0.44 1.62 0.60</size>
        </box>
      </geometry>
    </collision>
  </link>

### Attach Detail Collision Model to Actor (Plugin)

Follow the sdf format below to add the related plugin to your actor.  
This plugin will add a group of linked model to your moving actor.

```xml

### Trajectory for Actor (Plugin)

Follow the sdf format below to add trajectory plugin for your actor.  
This plugin will move your actor according to your specify target and will stop moving when your robot is blocking its way.  
Please specify your robot name at <obstacle> element.

```xml
<actor name="human_94763">

### Autonomous Actor (Plugin)

Please visit this [repository](https://github.com/BruceChanJianLe/gazebo-plugin-autonomous-actor) for more information.

### Trajectory and Collision Attach to Actor (Multiple Plugins)

Follow the sdf format to add multiple plugins to your moving actor.  
Here we will be adding the box collision model to a trajectory actor.

```xml

<model name="human_94763_collision_model">
