Innovation field tests for robotic broccoli harvesting performed in Quebec

The Sami 4.0 is an intelligent multifunctional agri system that can perform the work of traditional pickers of vegetables through an innovative vision system and robotic arms linked to artificial intelligence. By adding a mobile app, farmers will then be able to manage a harvest on their smart phone.

Sami 4.0 can work at the same tempo as a human harvester, except cut more because of the multiple robotic harvesting arms. The robot was developed by Lapalme Groupe Conception Mécanique of Varennes, Quebec.


Guided by 2D and 3D camera systems, Sami 4.0 uses its vision system to detect, position and qualify the broccoli. Following the detection, an analysis is made by artificial intelligence, which is sent to the robotic arms, telling it to harvest the crop—or not—based on its maturity/ripeness. A waterjet system using 50,000 psi is applied to cut the broccoli.

The Sami 4.0 utilizes artificial intelligence and was taught by engineers to recognize the vegetable broccoli, as well as how to make the required movement to harvest it. To that end, more than 500,000 photographs of vegetables were taken in its environment and in all possible weather conditions.
