Our implementation of the OA-Bug algorithm on the Lingao robot

OA-Bug-Robot

This repo contains our implementation of the OA-Bug algorithm on the Lingao robot. The platform includes at least the following (may work on other platforms):

• 64-bit Raspbian OS (Debian 10) on Raspberry Pi 4B with wiringpi

  • To install wiringpi on 64-bit Raspbian OS, you can use these commands:

    dpkg --add-architecture armhf
    sudo apt update
    sudo apt install libc6
    sudo apt --fix-broken install
    sudo apt install libc++6:armhf
    wget https://project-downloads.drogon.net/wiringpi-latest.deb
    sudo dpkg -i wiringpi-latest.deb
    gpio readall

• Python 3.6+

• ROS noetic

• libqt5charts5-dev

To run the robot, set up all the hardware and make sure roscore is running, then run python3 robot_using_ros.py to start.

For convenience, the robot can be monitored and controlled by a GUI, roughly following the MVC design pattern:

• utils.py contains some tools and classes to get data, which can be considered as Model in MVC;
• views.py contains components of the GUI;
• robot.py is the core logic of the OA-Bug algorithm, as the role of the Controller in MVC (for convenience, the function to update ControlPanel is implemented in the Robot class);
• state.py contains the abstract class for the state machine.
