Greenhouses are usually very humid but working close to the ceiling is the hardest as there is no shade. Thousands of hooks need to be rotated many times during the season to allow for continuous plant growth.
With a custom-made hook, our robot is able to lower the plants and move them forward. We do this with the same tool used for the other farming tasks. Detection of wires and various safety features including force measurements are necessary to make sure we don't drop the plants.
