ECSE473 Modern Robotic Programming Laboratory 2

This project was developed as part of ECSE 473: Modern Robotic Programming – Laboratory 2, which focused on visualizing a mobile robot model using URDF in RViz. The lab involved constructing a robot description package (navvis_description) that defines the robot’s physical structure using XACRO files, establishes static transforms between key components (e.g., base_link, imu, camera), and integrates the model with robot_state_publisher for real-time visualization in ROS Noetic.

Prerequisites

In order to launch the project, you should already have:

  • Installed ROS Noetic
  • The joint state publisher GUI 
    
  sudo apt install ros-noetic-joint-state-publisher-gui
  • Gazebo plugins 
    
  sudo apt install ros-noetic-plugins
  • Velodyne description 
    
  sudo apt install ros-noetic-velodyne-description

Available Parameters to use with display.launch

The launch file takes three arguments:

  • use_robot_state_publisher:= (true|false) - whether the robot_state_publisher will be used to launch (Added for Lab#3)
  • use_xacro:=(true|false) - whether the xacro file will be used to launch
  • file - file name
  • use_joint_state_publisher_gui=(true|false) whether the joint_state_publisher_gui will be used

View the Robot Description in rviz

  • rviz with the joint_state_publisher GUI

    • Launch by using the urdf file
    
  roslaunch navvis_description display.launch

    or by using some arguments:

    
 roslaunch navvis_description display.launch use_xacro:=false use_robot_state_publisher:=true use_joint_state_publisher_gui:=true
    • Launch by using the xacro file
    
  roslaunch navvis_description display.launch use_xacro:=true

    or by using some arguments:

    
 roslaunch navvis_description display.launch use_xacro:=true use_robot_state_publisher:=true use_joint_state_publisher_gui:=true

  • rviz with the joint_state_publisher GUI

    • Launch by using the urdf file
    
  roslaunch navvis_description display.launch use_joint_state_publisher_gui:=false

    or by using some arguments:

    
 roslaunch navvis_description display.launch use_xacro:=false use_robot_state_publisher:=true use_joint_state_publisher_gui:=false
    • Launch by using the xacro file
    
  roslaunch navvis_description display.launch use_xacro:=true use_joint_state_publisher_gui:=false

    or by using some arguments:

    
 roslaunch navvis_description display.launch use_xacro:=true use_robot_state_publisher:=true use_joint_state_publisher_gui:=false

    • rviz without both robot_state_publisher and the joint_state_publisher GUI (for purely static transformations as asked in the beggining for Lab#3)

        roslaunch navvis_description display.launch use_xacro:=true use_robot_state_publisher:=false use_joint_state_publisher_gui:=false
