The different folders:

• arduino: This folder contains all the arduino codes used within the 2 robots.
• documentation: The project documentation for the same year of Eurobot.
• ros_packages: Contains all our ros packages.
  • differential-drive: Provides some basic tools for interfacing a differential-drive robot with the ROS navigation stack. The intention is to make this independent of specific robot implementation.
  • differential_driver: package for the differential drive of Minus.
  • ecam_msg: contains custom messages for robots.
  • mecanum: package for the mechanic wheels of Cortex.
  • robot_2018: package that manages the launch of 2 robots.
  • robot_description: package that describes robots for simulation with rviz.
  • sensors: packages for ultrasound management.
  • strategy: package for the strategies chosen by the 2 robots.
