Mower Robot for Vineyards in Austria

Achieving precise mowing between grape vines by implementing an autonomous mowing robot system.

In viticulture, vines are planted in proximity to each other, which makes conventional care for erosion protection challenging and expensive. The area between the vine, however, must be kept clear to provide plants with sufficient amounts of water and nutrients. To address this challenge, the Flagship Innovation Experiment (FIE) develops an autonomous mower robot with a central computation system that fuses and processes all sensor data for path planning. To cope with the rough terrain and varying soil conditions machines need to have a certain size which significantly increases their costs.

This FIE thus strikes a balance between cost-efficiency and accurate plant detection to carry out precise mowing with the least possible impact on delicate ecosystems. Furthermore, a safety concept is developed to identify obstacles on top of haptic emergency bumpers. To achieve utmost precision for navigation, a visual odometry system is combined with existing GPS positioning. In contrast to conventional mowers, this mower robot’s autonomy allows it to mow as close as possible to the plants without damaging them unnecessarily. Full autonomy also implies that the robot needs to reach the charging infrastructure itself in order to work efficiently, all the while the FIE constantly evaluates the failure and effect analysis of the entire system.
