Autonomous feeding robot: first results

The initial step involved developing C++/Python code to perform the forage approach operation. This code was first tested in simulation, allowing rapid and cost-effective validation of multiple variations without requiring physical access to the robot. As a result, the software was robust and largely validated before deployment. However, simulations cannot fully replicate real-world complexities.

Following successful simulation tests, autonomous navigation was implemented, enabling the robot to move independently in mapped environments—though it cannot yet operate in unknown areas.

Once navigation was confirmed, focus shifted to designing and integrating the blade. The first prototype, made of aluminum by a company in Brescia, underwent lab testing before being deployed at Baroncina Farm (Lodi) for field validation.

This motorized blade is controlled directly from the navigation PC via a manufacturer-provided driver. Initial issues included limited tilt and insufficient length. While the tilt was improved through design modifications, the decision was made to postpone length adjustments until confirming the tool’s suitability for forage handling.

Modelling and simulation of robots for agricultural applications

Accurate modeling and simulation are essential for the design and validation of autonomous navigation algorithms. However, in agricultural applications, this task is particularly challenging due to the need for precise representation of tyre–ground or track–ground interactions.

This work aims to develop high-fidelity robot models, including detailed terrain representations, using an object-oriented, multi-physics modeling language such as Modelica. In parallel, it explores the development of computationally efficient yet accurate models using physics-informed neural networks.

Finally, the integration of models from both approaches with autonomous navigation systems—whether implemented in pure C++ or within a ROS2 framework—is also addressed.

Designing an autonomous stable feeding robot

In recent decades, agriculture and livestock farming have undergone significant technological advancements—from basic automation to the emergence of autonomous robots that support, and in some cases replace, farmers.

In livestock farming, key daily tasks include forage distribution, bunk cleaning, and milking. Foraging involves two steps: laying the feed and repositioning it as animals push it away while eating. While the initial laying requires large, complex machinery, repositioning can be done with simpler tools.

Today, small autonomous robots are available for this task. These robots follow fixed paths on flat, obstacle-free concrete lanes. However, their limited autonomy (about one hour) and inability to navigate uneven terrain restrict their use to one or two stables. Multi-stable solutions require dedicated paths, buried guide wires, and still struggle with obstacle avoidance.

This project, funded by Fondazione LGH E.T.S. aims to develop an advanced autonomous robot for barn automation with the following features:

  • Over one hour of working autonomy to serve multiple stables per charge
  • Autonomous navigation across varying terrain without the need for guide lines
  • Real-time obstacle detection and avoidance

Designed for farmers in the Cremona area and similar small-to-medium-sized operations, this solution addresses the high cost and infrastructure demands of existing systems.

Coordinated system of gates for flood irrigation management in paddy rice farm

Rice is one of the world’s most important staple crops, and in Europe, Italy is the leading producer, particularly in the northeastern regions. Traditionally, rice cultivation involves flooding fields from before planting until just before harvest. Maintaining this water level requires significant labor, as farmers must manually operate inlet and outlet gates. Moreover, this method results in high water consumption.

To address these challenges, new technologies using remotely and automatically controlled gates are being explored to improve irrigation efficiency. This research investigates the feasibility of an intelligent, synchronized gate system aimed at optimizing irrigation management and regulating ponding water levels more effectively.

AGRITECH National Center for Technology in Agriculture

Producing sufficient and safe food for a growing population without over-exploiting natural resources is one of the major problems that our society must face, finding solutions which are sustainable in the long term. This is a global challenge, placed in a difficult context of unstable climate, increasing competition for land, water and energy, in an increasingly urbanized and globalized world.

ROSETEA lab participates to the National Center for Technology in Agriculture AGRITECH, in particular to Spoke 3 (Enabling technologies and sustainable strategies for the smart management of agricultural systems and their environmental impact) and to Spoke 8 (New models of circular economy in agriculture through waste valorization and recycling).
