The future of farming could involve robots– as farmers seek to address labor shortages and increase crop yields.
Researchers at WMG at The University of Warwick are investigating how they can apply autonomous robotics to greenhouses and croppable fields.
Continuous and repetitive monitoring of crops is vital for fruit and veg production, as the sooner that pests, diseases, and infrastructure issues can be spotted, the sooner they can be rectified. This means that growers get the information they need to make quick decisions that save their crops and reduce losses.
A Crop Monitoring Robot (Crombot) is proving that robots could become the perfect helper to support growers – especially when faced with labor shortages. Crombot is an autonomous four-wheeled robot, able to navigate itself around a greenhouse, avoiding other workers and even following specific workers on command.
Crombot's robotic arm has a camera on the end, which allows it to carry out all the required monitoring duties and can even identify the ripeness levels of strawberries, letting the grower know which areas of the greenhouse are ready to be picked.
Working with local salads producer Valefresco and technology developer Eiratech, the team is now working on expanding Crombot's capabilities to monitor leafy greens and will also be looking at how the use of microphones could pick up on infrastructure issues such as leaky irrigation systems, which impacts the crop's hydration levels.
Other developments by the group include 'Spot,' an autonomous four-legged robot dog supplied by Boston Dynamics for use in agriculture. Spot is designed to work in difficult and hazardous environments, and this innovative robot system has proven itself so far to be very impressive in handling a variety of greenhouse and outdoor environments.
Benefits of this system include being able to walk up and down steps, overheating rails, and other obstacles, as well as tackling muddy fields.
By working in close collaboration with the University's School of Life Sciences (SLS) at the Warwick Crop Centre on the Innovation Campus Stratford-upon-Avon, the WMG team has been able to combine their robotics expertise with the plant science expertise of SLS to create this extremely promising research. This has laid the foundation for the group to explore new capabilities, such as automated planting and harvesting.
Harry Boyce, Project Engineer at WMG at the University of Warwick, added: "Our research with Crombot aims to address growers' skepticism of new technology and, most importantly, cost. It will unlock the potential for the adoption of robotics solutions in horticulture and facilitate a UK offering to a huge global market."
Alex Keller, Principal Engineer at WMG at the University of Warwick, said: "Boston Dynamic's Spot robot could be an ideal solution for an agricultural monitoring robot, but it is currently very expensive, and further research is needed to understand if Spot could progress to challenges such as harvesting and more."
"This is why we are continuing to develop our in-house robotic capabilities so that we can help the industry to create robotic solutions that are affordable and realistic for the grower, which still deliver high impact and high return on investment."
"We hope to hear from growers who would like to be involved in this research – finding out how they can incorporate robots in their practices too."
