# sign_description
## Description
This package contains the urdf and launch files to load road sign images, which can be used in simulation.
Developed at Institut de Robòtica i Informàtica Industrial (IRI, CSIC-UPC) (
## Installation
Clone the package inside a ROS workspace, although it will normally come within a rosinstall file.
Move to workspace:
roscd && cd ../src
Clone the repository:
git clone
Install all ROS dependencies with the following commands:
cd ..
rosdep install -i -r --from-paths src
Compile all the ROS packages with the following commands:
## Launch
This package file includes a launch file named spawn_sign.launch which is intended to be included from other launch file that requires to spawn traffic signs in a simulated Gazebo world. This launch file has the following parameters:
* **name**: (default=stop1) name given to the traffic sign used to to name the nodes and topics associated with the sign description.
* **model**: (default=sign) URDF model to use. At the moment only static traffic signs are supported.
* **tag**: (default=alvar0) Name of the Alvar AR tag used to identify the traffic sign.
* **type**: (default=stop) Type of the traffic sign. The currently supported types are: giveway, haveway, max_100, max_50, no_entry, no_overtaking, one_way, parking, pedestrian_crossing, roadworks, roundabout, stop, unmarked_intersection and ahead_only.
* **x** (default=0.0) x position where the traffic sign will placed in the simulated environment with respect to the parent frame.
* **y** (default=0.0) y position where the traffic sign will placed in the simulated environment with respect to the parent frame.
* **yaw** (default=0.0) orientation of the traffic sign with respect to the parent frame.
* **parent** (default=map) parent reference frame used to place the traffic sign in the simulated environment.
To spawn a traffic sign from an other launch file, include the following lines:
<include file="$(find sign_description)/launch/spawn_sign.launch">
<arg name="name" value="$(arg name)"/>
<arg name="model" value="$(arg model)"/>
<arg name="tag" value="$(arg tag)"/>
<arg name="type" value="$(arg type)"/>
<arg name="x" value="$(arg x)"/>
<arg name="y" value="$(arg y)"/>
<arg name="yaw" value="$(arg yaw)"/>
<arg name="parent" value="$(arg parent)"/>
A test launch file is provided to visualize the traffic sign in RVIZ. To use it, execute the following command:
roslaunch sign_description spawn_test.launch
