Rotair crawler machines, traditionally used in vineyards for tasks like spraying, are being adapted by Swiss companies to operate fully autonomously. This initiative, led by the Swiss firm STEV-Motion and the Jaquerod and Fils vineyard estate in Ollon, aims to address the growing challenge of finding workers to manage these machines, especially on steep slopes. The partnership has already produced the first autonomous Rotair R70.3 D13 model, which completed testing in the spring and began demonstrations this summer. The machine uses a combination of GPS and inertial technology to navigate vineyard terrain accurately, and it can be controlled manually, remotely, or on its own. The autonomous system relies on two RTK GPS antennas that provide precise location and orientation data, along with an inertial central unit that helps the machine adjust to slopes and turns. This setup ensures stability and accuracy, even on uneven ground. A Lidar sensor adds an extra layer of safety by detecting obstacles in the machine’s environment. Unlike other automated systems, this model does not require internet access or cloud-based tracking. Instead, all data is stored locally on the machine, making it more reliable in remote or harsh conditions. The system is configured using a surveying pole to mark the machine’s path, after which it can operate independently. To enable autonomy, the Rotair crawler has undergone several modifications, including the addition of solenoid valves to its hydraulic system and a dual-control pump that allows both manual and automated operation. These changes make the machine versatile, capable of performing a range of tasks such as mowing, mulching, and soil preparation, though it is not recommended for pruning or weeding. The Jaquerod sprayer, which includes a jet-powered aeroconvecter and a 175-liter tank, can be adapted to fit the crawler, just like standard Rotair equipment. The autonomous Rotair R70.3 D13 model has now passed certification and is entering commercial production through the Jaquerod company. The initial cost is approximately 65,000 euros, which is nearly double the base model. While this price is currently due to the added technology and parts, the dealer suggests that costs could decrease if Rotair agrees to integrate these features directly at the factory. The company also plans to explore adapting other Rotair models in the future. Meanwhile, the Vineatrac machines from STEV-Motion will continue to be produced only for specific requests that the new autonomous model cannot address.
