## Run IAN in a Simulation

```bash
source ~/IAN/ianvenv/bin/activate
source ~/IAN/ian_ws/devel/setup.bash
rviz -d ~/IAN/ian_ws/src/interaction_actions_for_navigation/external/asl_pepper/rviz/ia_sim.rviz &> /tmp/rviz-log &
roslaunch ia_ros auto_ros_ia_node.launch
```

This will launch a self-running example, where a goal is automatically provided.

## Run IAN on a Real Robot

here's an example launch file for running IAN on our robot:

```xml

<launch>
  <arg name="mapname" default="rik_bananas" />
  <arg name="mapfolder" default="$(env HOME)/maps"/>

<include file="$(find asl_pepper_gmapping)/launch/gmapping.launch" if="$(arg localization)">
    <arg name="output" value="log"/>
  </include>
  <include file="$(find map_matcher)/launch/map_matcher.launch" if="$(arg localization)">
    <arg name="output" value="log" />
    <arg name="slam_map_topic" value="/gmap"/>
    <arg name="reference_map_name" value="$(arg mapname)"/>

  </include>
