Live grain robot demo success on farm in the South West

On Tuesday 14th March Agri-EPI hosted a live demonstration of the Crover grain monitoring robotic solution at Manor Farms, Stratton-on-the-Fosse, kindly hosted by Jeremy Padfield and Rob Addicott who farm in partnership together.

They are both tenants of the Duchy of Cornwall and have been a LEAF Demonstration Farm since 2006 and members of the Agri-EPI Innovation Farm network since 2017. Working together as neighbouring farmers has brought many benefits to Rob and Jeremy such as shared machinery and investment costs. It has also allowed them to take up a number of precision farming techniques to help their businesses become more sustainable, such as engaging in the Crover project.

Crover’s first-of-its-kind grain monitoring robotic solution allows for a greater understanding of the real situation of grains stored in bulk, thanks to its patented method for locomotion through bulk solids, enabling grain storage operators to implement accurate Integrated Pest Management (IPM) practices to maintain the quality of their stock. The CROVER robot is the world’s first ‘underground drone’ in the sense of the first device able to propel itself below the surface of dense granular media such as sand, grains and powders.

It was a very successful event with great feedback and engagement from the guests and the demonstration in the grain shed went smoothly.

International Day of Mathematics

Happy International Day of Mathematics! Mathematics plays a significant role in agricultural technology in several ways:

  1. Modeling crop growth: Mathematical models are used to simulate the growth of crops. These models use mathematical equations to represent the different factors that affect crop growth, such as temperature, rainfall, soil nutrients, and pests. By using these models, farmers can predict how their crops will grow under different conditions and make informed decisions about when to plant, irrigate, fertilise, and harvest.
  2. Precision agriculture: In precision agriculture, farmers use technology to apply inputs (such as water, fertiliser, and pesticides) precisely where they are needed. This technique relies heavily on mathematical models, data analytics, and sensors to measure and monitor different parameters, such as soil moisture, nutrient levels, and pest populations.
  3. Farm management: Farmers need to keep track of a lot of data, such as crop yields, soil characteristics, weather patterns, and market prices. Mathematical tools help them organise and analyse this data, make predictions, and optimise their operations.
  4. Genetics and breeding: Mathematics is also used in genetics and breeding to study the inheritance of traits and develop new varieties of crops that are more productive, disease-resistant, and climate-tolerant. Mathematical models can help researchers identify the genes that control these traits, predict the outcomes of different breeding strategies, and optimise the selection of new varieties.

Overall, mathematics is an essential tool in agricultural technology, helping farmers and researchers make informed decisions and optimise their operations to meet the growing demand for food in a sustainable way.

Over the last months Agri-EPI has invested in the expansion of its team focused on data, engineering, and math, bringing on several new members and enabling them to offer a set of services to assist in the creation of agri-tech products.

Eliot Dixon, Head of Engineering, said:

“The team of platform and spectral imaging experts uses our fleet of sensors and specialist software to deliver a range of sensing products such as ground truthing for AI model generation, or the creation of digital twins. We are also now able to offer UAV and UGV platforms as a means to test novel sensors and end-effectors without the need for a bespoke vehicle. And through working closely with our innovation farm network, we are creating a heavily layered source of evidence for developers using our farm network to design and test their innovations.”

Agri-EPI’s GIS Data Analyst, Yingwang Gao, majored in Agricultural Engineering, and has a PhD degree specialising in Hyperspectral Imaging Applications, as well as postdoc experience working as Research Associate. In addition to a strong academic background, he has accumulated several years of industrial work experience, mainly on spectral imaging systems, R&D, and spectral imaging data analysis in various application domains. He has a strong passion for remote sensing and photogrammetry. At Agri-EPI, he takes care of data acquisition and data processing from different types of sensors, including RGB, multispectral, hyperspectral, LiDAR, and GPR, to identify and map out features of interest in the agricultural sector, to help farmers with better decision-making in agricultural management.

Agri-EPI’s new R&D Equipment Technician, Aditya Jadhav, pursued his bachelors in aeronautical engineering, where he learned various aspects of flying machines. He set up an aeromodelling club with a few of his classmates where they designed, built and tested various configurations of small UAVs. The MSc program for Autonomous vehicle dynamics and control was structured for students to gain a deeper understanding of unmanned systems. Aditya was part of a group project that built a surveillance system with a swarm of autonomous drones, and an individual project sponsored by the Railway Safety and Standards Board which aimed to design and develop an autonomous vehicle which can operate in a station environment. The advancements in robotics and the urgent need of integrating robotics with sustainable agriculture were the driving forces for him deciding to work in the agri-tech sector. As the R&D Equipment Technician, Aditya looks after all the deployable assets that are in service to the company, which includes maintenance, asset tracking and deployment, and organising the logistics.

Panagis Tzivras, Agri-EPI’S GIS Software Engineer, is a GIS expert with strong technical skills who is highly invested in programming. In his previous roles working with startups and the commercial sector, he was involved in data collection and extraction, maintaining data pipelines and building geospatial processes and automation updates. At Agri-EPI Centre he is helping to leverage the measurement resources of the centre to create high quality dataset and support systems. He is working on creating tools and code to enable the automation of data collection from a wide variety of sources available to Agri-EPI Centre.

Lastly, Aidan Robertson has joined the Agri-EPI Engineering team as their new Graduate Data Analyst. Aidan’s background is in mathematics, which he studied at University of Warwick for four years before looking for jobs related to data science. He has been working on projects related to the health and wellbeing of cows, specifically by reformatting farm datasets to be sent out for analysis. Soon, there are plans for him to begin a more ambitious project to develop a costings estimator for RAS in agriculture. This is a long-term task, but the ultimate goal would be to offer it as a service for farmers looking to introduce robotic systems into their farms. The most interesting part of agri-tech for Aidan is the data, and what it actually says about the performance of a system, as well as what can be done to help the problems being faced by the agri-tech sector at present.

Member case study: Earth Rover delivers sustainable weeding technology 

With increasing types of chemical-resistant weeds, a significant downturn in availability of hand labour plus a shift in society towards more organic options, now more than ever there is a need to change the way we farm. A recent report by Rothamsted Research shows weeds “pose an unprecedented threat to our food security” and highlights the need to diversify weed control as an urgent priority.

Earth Rover has developed the CLAWS rover (an acronym for Concentrated Light Autonomous Weeding and Scouting), with funding from Innovate UK as part of the Farming Innovation Pathways industrial research, and in collaboration with project partners Pollybell Farms and Agri-EPI Centre. The rover uses AI and robotics to accelerate crop growth by removing weeds, including herbicide-resistant weeds, without disrupting the soil, generating a more sustainable and effective alternative to other weeding techniques in the agriculture industry.

Collaboration essential for successful agri-robotics

By: Eliot Dixon, Head of Engineering at Agri-EPI Centre

Robotics has several strong applications in agriculture, especially in scenarios where systems can enhance the productivity of a shrinking workforce or can offer production efficiencies to the farm. However, to be successful in these applications the systems created need be reliable, in terms of long-term physical robustness but also in the ability of their control software to handle the very wide variety of scenarios they will encounter in a farming environment. This means the robots must be both well designed and well tested to meet the needs of farmers. This includes a design which emphasises safety and reliability.

“Understanding user requirements and testing in-field is key”

Good design requires a deep understanding of the needs and requirements of farmers and their farming systems. This extends from the core values held by a farmer, such as safety, which dictate their decisions; through to very specific requirements created by the unique combination of their way of working and the land they work. If this understanding is not achieved for a farming system, then there is a very high chance that the eventual product will be unsuitable, either creating a failed product or a long development timeline to solve the deficiencies. Gaining this understanding should come through working with a wide variety of farms within the target market for the technology, not just a small handful. In many agricultural sectors this design stage is especially important due to the limited testing season and ability to iterate on the design.

Testing is also well understood to be important to creating a reliable product, and in agriculture this does require a close collaboration with farmers to ensure that the robot meets their needs. As these are complex machines, which are also often dangerous if not created with a strong safety process, the testing regime should also be rigorous enough to ensure that the system will function to the desired reliability for all the design requirements. A rigorous testing regime would usually require multiple tests for each requirement across multiple operational scenarios such as different weather conditions, soil types, dangers, failure modes, crops etc. Failure to complete this testing will certainly result in the robotic system encountering situations which it is unable to function within, which may create unfortunate repercussions for the user or manufacturer. Unfortunately, completing this massive number of tests requires a range of test facilities, some of which might be beyond the capability of a company focussing on a small range of agricultural applications.

In our 2021 hackathon we explore safety and security. Outcomes are discussed in our white paper here:

Hackathon white paper

As mentioned, good design and testing is essential to creating successful products, but this unfortunately comes with a high cost. Doing this for the wide range of complex operating scenarios in UK agriculture, as well as the short testing cycles, is driving up the cost of developing agricultural robots. There are a multitude of Agri-robotics companies in the UK creating their systems from almost the ground up, each of which are individually bearing the cost in time and money of this development. This creates barriers to adoption in terms of high costs, a limited set of operations which can be conducted by robots, or low reliability due to poor engineering, and is increasing the amount of time it takes for products to get to market. As in all development the saying “Good, Cheap, Fast. Pick two”, is very much in action here but some very pressing needs mean we must find ways to break that deadlock.

Collaboration enables future opportunities for robotic systems

The obvious solution for this deadlock is to massively increase collaboration between ag-robotics developers. This has been proposed for many years, but we are yet to see a viable solution to this. Direct collaboration is currently difficult for commercial reasons with developers competing for the same money, but also for technical reasons where it is challenging to share components between robots. Perhaps a solution for this is to build an ecosystem of adaptable, compatible, components and platforms which can be used to create a multitude of agricultural robotic systems. This ecosystem of components would also be able to be robustly tested to ensure reliability when integrated as part of a larger system. Thus, the costs of development would be increasingly shared, without any single robotics manufacturer losing income as they are all developing for specific agricultural niches. Using a set of well proven components would allow developers to focus on ensuring good understanding and design for specific problems in agriculture, while also allowing for easier integration and testing of the robots.

Robotics in agriculture is a promising field, and with the right design and testing, as well as collaboration between developers, it could be a great success. By understanding the needs and requirements of farmers and using that to create an ecosystem of components and platforms, robots can be developed which are high value, robust, reliable and safe. With the right approach, agricultural robotics could benefit farmers across the UK and worldwide.
