Setup

To use this package you first have to install the L-CAS Ubuntu/ROS software distribution. To do so, do:

1. sudo ls (this is just to cache you admin password for the next steps)
2. sudo apt-get update && sudo apt-get install curl (curl is required for the next step)
3. curl https://raw.githubusercontent.com/LCAS/rosdistro/master/lcas-rosdistro-setup.sh | bash - (should install everything required)

Then clone the main CMP9767M package, and our package in your catkin workspace:

cd ~/catkin_ws/src
git clone https://github.com/LCAS/CMP9767M
git clone https://github.com/NekSfyris/weeding_bot
cd ..
catkin_make

After you are done with that with no erros, do:

pip install scipy==1.2.0

In case any other package is missing, you can install it with:

sudo apt-get install ros-melodic-<package_name>
