Arduino_Raspberry_ROS_Car Tutorials

chapter 1: Construction A ROS Car

Download codes from Git:

git clone https://github.com/COONEO/Arduino_Raspberry_ROS_Car.git

Step One: Download programs for Arduino Mega 2560

Install Arduino IDE in your computer and add library where in Arduino_mega_2560_code/relative_library folder.than,download the code into your Arduino_mega_2560 board.

Step Two: FLASH OS and LAUNCH ROS NODE

1.flash Ubuntu OS into your Pi 4B board (By Win32DiskImager.exe)

The OS img can be finding in our Wechat Official Account COONEO. Process like this:

2. launch ROS node in Raspberry Pi

   #connect Raspberry Pi and Arduino
   sudo chmod 0777 /dev/ttyACM0
   
   #open a Terminal &&  download codes
   git clone https://github.com/COONEO/Arduino_Raspberry_ROS_Car.git
   
   # copy ROS node in your home folder
   cp -r Arduino_Raspberry_ROS_car/Raspberry_Pi_ROS_Node/catkin_ws ~/
   
   # change *.py file's permission 
   sudo chmod 0777 Arduino_Raspberry_ROS_car/Raspberry_Pi_ROS_Node/catkin_ws/src/ros_arduino_bridge/ros_arduino_python/src/ros_arduino_python/*
   
   cd catkin_ws
   catkin_make
   source devel/setup.bash
   roslaunch ros_arduino_python arduino.launch

   In the end,you can publish Topic "cmd_vel" msg to control ROS car runnning。
