Leaf Cutting Robot

ALTEN, in collaboration with a Dutch company specialized in machines and mechatronic systems, develops an innovative solution to automate the leaf cutting process in greenhouses.

The solution uses artificial intelligence, algorithms, and path planning to achieve this. The system moves around in the greenhouse by means of navigation. While driving, the system will stop at specified distances, takes an image of the crop, that is analyzed by multiple algorithms, so the exact position and orientation of the gripper are determined. Using a SCARA robot, in combination with a self-developed gripper, the system moves towards the cucumber leaf to cut it according to the guidelines of the greenhouse grower.
