An extensive study of the sequence of incidents that happened in the recent past which had AI as the subject under scrutiny signalled one thing in unison, and that is that AI is essentially bad. Not because it was programmed to be a villain, but because humans manoeuvred it in such a way that it has involved itself more with mis-deeds than good. However, its character arc is not linear because the 2023 edition of the ‘AI for Good’ Global Summit that took place this July proved that AI is a domain with many faces, especially when it comes down to the use of AI in the field of agriculture.
This global summit provided a platform for over 30 cutting-edge robots to exhibit their range of skills which served as a testament for the potential of autonomous robots to spearhead progress towards the United Nations’ Sustainable Development Goal. Amidst the participants were robots that could be used in agriculture who displayed the importance of using high-technology in the field of agriculture. What it also showcased is how agriculture serves as a breeding ground for new technological developments and also as a key area of application of technologies that were developed somewhere else.
Robots and agriculture, a collaboration that we didn’t know we needed
The utilisation of AI in the agriculture market is expected to grow from US$ 1.7 billion in 2023 to US$4.7 billion by 2028. Despite this initiative being in its embryonic stage, these numbers do not come as a surprise especially because in a world where the demand for food is steadily increasing, agriculture is turning to innovative solutions, primarily robots, to optimise farming operations. The advanced machines that come into play are becoming the new workforce in agriculture and they have the ability to perform different tasks such as planting, irrigation, pest control, and soil analysis. Automating the field of agriculture can reap benefits such as higher productivity, lower labour expenses, and reduced reliance on harmful chemicals.
Farmers far and wide have already begun to embrace technology, including drones and remote-controlled grass and scrub cutting machines to improve productivity and minimise downtime and monitor their livestock with efficiency. For instance, in hilly regions, these robotic machines are particularly valuable as they can access and cultivate land that was previously unusable. Additionally, electric farm and factory robots with interchangeable tools are being developed, allowing for precise soil management minus the negative impacts of heavy tractors compacting wet soil. Soft robotic grasping technologies and sensors are helping out in the production of delicate crops giving farmers and consumers both something to look forward to. Moreover, soft robotics employs gentle methods like rubber cups or small bean bags to delicately grasp and harvest high-value produce like peaches and raspberries from plants without causing any form of damage. Thus, preserving the quality of such delicate crops.
Robots that are used in agri-tech are as cool as ones you see in ‘The Transformers’
Optimus Prime may be a master in hand-to-hand combat and a prodigy in parkour, but RoboBees (which can take-off vertically, hover and steer) could very well outdo it in terms of efficiency. Sarah Murray writing for The Financial Times about ‘Farm Robots Poised For Growth as Labour Costs Rise’ explains how RoboBees; developed by researchers at Harvard’s Wyss Institute, one of the most recent initiatives and is still in its nascent state, has the potential of eventually performing tasks such as crop pollination and environmental monitoring.
Currently, RoboBees are confined to laboratory settings, and their widespread commercial use in agriculture is still a distant prospect. These laboratory settings are spaces such as polytunnels and glasshouses where there is an absence of rain and mud. However, the ongoing progress in technology, coupled with challenges related to labour shortages, is making robots increasingly economically feasible for farm applications. This suggests that as technology continues to advance and labour availability remains a concern, the adoption of robots in agriculture may become a more realistic and practical solution in the near future. Furthermore, the fact that most of these robots are tailor-made and are often streamlined to function on a more plant-by-plant approach makes them even more attractive. For instance, ‘FarmWise’, a company based in California, has created a weeding robot that prioritises computer vision and artificial intelligence. This innovative robot can differentiate between weeds and crops, resulting in reduced labour expenses for farmers and allowing them to reduce their herbicide usage.
Another innovation that was exhibited at the ‘AI for Good’ Global Summit is ‘Digital Farm Hand’: a robotic platform specifically designed for smallholder farms, created by University of Sydney’s Australian Centre for Field Robotics (ACFR). This robot is programmed in a way that it could detect and identify objects within its environment, including plants and weeds. Owing to a capability of that scale, it can perform various tasks such as field mapping and gathering data on crop health and yield. But the feature which triumphs amidst all the ones it possesses is its capacity to transform the farming industry. By automating the process of recognising and removing weeds, this robot has the potential to decrease the dependence on harmful chemicals by farmers. This leads to cost savings and contributes to a safer and healthier environment for all parties who are shareholders in agriculture.
But do these robots live up to their brand image?
The potential that robots have cannot be denied. However it is worth highlighting that whether or not this potential will be discovered is up to the economic and political choices that the agricultural industry makes. For instance, a concern that is associated with the widespread adoption of agricultural robots is, when the costs of applying pesticides are diminished due to automation, it might lead to increased pesticide usage rather than a reduction, which could have adverse environmental and health implications. In addition, the use of more potent and hazardous pesticides might become more prevalent without human oversight. If heavier robots replace human workers, this could exacerbate existing issues related to soil compaction caused by the use of heavy machinery in farming, potentially harming the quality of the soil. The concerns don’t end there. The standardisation of food items to accommodate robotic automation may create a consumer expectation for perfectly uniform produce. This expectation could result in increased food wastage as fewer items meet these stringent criteria for sale, even if they are perfectly safe and nutritious to consume.
Apart from that, a major issue that has many small farm owners worried is that most efficient and high quality robots that are manufactured are available at extremely high costs. This will automatically gate keep them from gaining access to machinery that can actually make a change. This scenario can change if smaller, more advanced and affordable mobile robots become available for smaller farms. However, currently, most manufacturers of farm equipment are mainly focused on automating their large and more expensive products. This means that larger agricultural producers are the ones who will have a competitive advantage, as they can harness the cost savings and productivity benefits of robots. It is vital that the decisions that are made with regards to integrating robotics into agriculture are done wisely and done in a way that has everyone’s best interest at heart. The minute that it is politicised, it will stray away from the path that leads to achieving the goal of using robotics for SDGs. It will eventually become an antithesis to what experts recognise as measures used to ensure food security and combat climate change.
