About the Project

This simulation package was developed during the Robotcraft '19 program. A basic right hand follower algorithm was provided by the supervisers but we decided to tune a P(ID) controller, which resulted in a smoother drive than anyone for the amazebot !

Setup

To setup ROS, run the "install_melodic.sh" script in the scripts directory using sh install_melodic.sh or chmod+x scripts/install_melodic.sh && ./ install_melodic.sh

You can also use tutorials. There's a bunch of them, including in the ros wiki.

Now that you have ROS, to setup the project on your local machine:

  1. Click on Fork.
  2. Go to your fork and clone the project to your local machine, in the "catkin_ws" folder.
  3. git clone https://github.com/robotcraft19/robotcraft-ros-navigation.git
  4. Make sure you have rosdep install : sudo apt-get install python-rosdep && sudo rosdep init
  5. cd ~/catkin_ws
  6. rosdep install --from-paths src --ignore-src -r -y
  7. In the catkin workspace : catkin_make

If everything went smoothly, you should now have this repo's package as well as its dependencies.

Run

Running the nodes is quite easy as launch files were made.

Reactive Navigation :

  • Circle Maze : roslaunch robotcraft-ros-navigation circle_maze.launch
  • Worldmap Maze : roslaunch robotcraft-ros-navigation reactive.launch
  • Square Maze : roslaunch robotcraft-ros-navigation square_maze.launch

Teleoperation :

  • Only one map available : roslaunch robotcraft-ros-navigation teleop.launch
