Robotic arms for precise weed cutting in bumpy fields

Robotic arms are used in agricultural systems to cut weeds without damaging plants/nThe robotic arms used have three degrees of freedom: left-right movement, rotation, and up-down movement/nThese three degrees of freedom allow the blades to follow a path that accommodates the bumps and uneven terrain of the field/nThe precision achieved by the robotic arms is sufficient for the desired 2D plane with hills and valleys/nThe robotic arms used are not complex or expensive
