Recently, Austin, Texas performed host to the 2023 John Deere Technology Summit. A choose variety of outstanding journalists, thought leaders and social media influencers within the subject of expertise have been invited to attend this inaugural occasion, the place they realized concerning the state-of-the-art in agtech from John Deere’s expertise executives.
I used to be lucky to be invited to attend this occasion on behalf of The Robot Report. The occasion featured a full day of in-depth displays and in-field demonstrations on the newly christened John Deere check farm close to Elgin TX, northeast of Austin.
John Deere is a software program firm
John Deere CTO Jahmy Hindman kicked off the occasion with a high-level overview of expertise improvement at John Deere (JD). Over the final 5 years, the corporate has grown its software program improvement group by 350% and now employs 4,300 software program engineers.
“Our mission by 2030 is to make sure every one of the 10 trillion corn and soybean seeds can be planted, cared for, and harvested autonomously. If the farmer chooses to do so, that’s going to require this full complement of the John Deere tech stack”, mentioned Hindman.
Deanna Kovar, John Deere’s VP of Production and Precision Ag Systems, took the gang down historical past lane by recapping a few of the key milestones for John Deere precision agriculture since its founding in 1837.
Autosteer is the muse
The first key excessive expertise milestone for John Deere was the introduction of GPS – Navcom within the Nineteen Nineties. This enabled JD to deploy autosteering for tractors whereas bettering the accuracy and repeatability of assorted crop administration processes. Autosteering additionally helps to scale back the psychological stress for the tractor driver, whereas additionally decreasing the talent stage essential to ship precision agriculture. For the farmer, this permits much less skilled drivers (like teenage kids/grandchildren or farmhands) to drive the tractor with correct outcomes.
Autosteer is now an possibility on each trendy John Deere tractor. During the harvest, grain wagons can sync with the mix and match the pace and path of the mix through the grain offloading course of. This easy course of reduces the psychological stress and fatigue on the mix driver and helps with the throughput through the time-critical harvesting course of.
The subsequent large expertise milestone got here in early 2010 when JD launched IOT infrastructure to the farm that linked each machine and farm implement. This was the beginning of the precision agriculture knowledge tsunami and required further innovation to ingest and course of a rising mountain of knowledge. This info would type the idea of data and decision-making instruments like yield maps, stress maps and chemical utility maps.
Autonomy makes its debut in 2020
Finally, in 2020, JD launched its first totally autonomous tractor, the John Deere 8R, which leverages laptop imaginative and prescient and machine studying to allow the tractor to understand the world round it, determine obstacles and safely function with out an onboard operator.
Along the best way, JD acquired Blue River Systems and Bear Flag Robotics to assist infuse the JD engineering crew with the IP and technical sources essential to develop on the tempo obligatory to stay a number one AgTech provider. John Deere additionally maintains a silicon valley improvement middle and laboratory the place it helps the accelerating push for innovation.
Tractor autonomy stays a key funding space for JD. However, there are different key areas of innovation which might be viable for agriculture automation right this moment together with the planting and spraying workflows.
AI is essential to good spraying
Another current innovation is the See and Spray expertise that JD acquired by Blue River Systems. JD has commercialized this expertise that leverages machine imaginative and prescient and AI/ML to tell apart and determine crop vegetation from weeds after which solely spray the components of the sphere when a weed plant is current. Note that this workflow is extremely aggressive with plenty of rivals on this area utilizing the whole lot from lasers, to robotic weeding implements, to vision-guided chemical functions.
The newest era of the See and Spray answer now contains an auto-leveling carbon fiber growth together with twin nozzles that may ship two completely different chemical substances in a single cross.
John Deere expertise helps farmers lower your expenses
In planting, the important thing innovation known as ExactShot and is concentrated on optimizing one of the crucial necessary processes in farming. Mechanized seed drills have been round for tons of of years. Until lately, nevertheless, the traditional seed drill was “open loop” the place the farmer would arrange the seed drill, run it for a few minutes after which cease the tractor, and undergo the planted seed furrows to find out the success of the planting course of by digging by the planted floor with a screwdriver. He would then make some mechanical changes, run it for just a few extra minutes, cease, recheck, and many others. This course of didn’t simply account for native soil variability between fields and even inside a given subject. The outcomes weren’t optimized with some particular person vegetation affected by insufficient planting depth.
With ExactShot “Rowbots” mixed with ExactEmerage and a brand new fertilizing answer known as SureShot, John Deere is utilizing sensors, imaginative and prescient cameras, machine studying and onboard processing to fully optimize the planting course of. The ExactEmerge system can see the profile of the furrow in real-time and make changes to the discs to create an ideal seedbed for each seed, whilst topsoil situations change. ExactEmerge is able to planting over 40 seeds per second, 12 hours per day.
The SureShot expertise (see video beneath) sprays a shot of fertilizer on every seed, optimizing fertilizer utilization. Older generations of expertise would merely spray a relentless quantity of fertilizer all through the method, losing any fertilizer not instantly subsequent to a seed. Up to 54 ExactShot planting Rowbots will be configured in parallel on a contemporary planting platform.
Tillage is the primary workflow to be totally automated by the brand new John Deere 8R autonomous tractor. There are a few key the explanation why tillage is a candidate for automation. First of all, tillage occurs instantly after harvest, a time when the farmer is commonly busy getting the harvest to market.
Secondly, the tillage implement is “dumb”, it merely must be dragged by the soil and the accuracy is much less vital than with planting or harvesting. Also, in contrast to planting or harvesting, there’s nothing to reload or offload from the tractor/implement. This implies that the autonomous tractor can run till it must be refueled, which will be as much as 8 hours. Lastly, tillage is a course of that’s usually performed by farm fingers or the subsequent era (youngsters or grandkids), and this can be a key space of labor scarcity for a lot of farmers right this moment.
The web result’s that tillage is a key goal marketplace for autonomous tractors, and John Deere is deploying a lot of autonomous tractors into the sphere this upcoming rising season. As autonomy improves and turns into extra sturdy, autonomous tractors will likely be deployed into different workflows in future years.
In March of this 12 months, John Deere acquired SparkAI, an organization that developed a “human in the loop” expertise and course of to assist get well autonomous autos once they grew to become confused or encountered an edge case in impediment detection/notion. JD has been working with SparkAI for the final couple of years and can now totally make use of this expertise to assist enhance buyer expertise with the tractors within the subject.
Rural high-speed bandwidth is a barrier to autonomy
High-speed connectivity is the one big hurdle that is still to the profitable deployment of autonomous tractors. John Deere 8R autonomous tractors can solely function when there’s a high-speed, high-bandwidth connection to the tractor and to the farmer. This is required primarily to attach the tractor to the farmer who can remotely management the tractor operation by way of a cellphone or pill. The second requirement is for the human-in-the-loop (SparkAI) performance, which is the primary line of help for JD.
Farms or fields which lack a high-speed mobile connection can’t at present function an autonomous 8R tractor. Brazil is a key agricultural marketplace for John Deere and it sadly can be one of many nations with a low share of rural high-speed connectivity protection. Thus Brazil is more likely to be locked out of utilizing autonomous tractors till the connectivity problem is resolved.
John Deere is actively exploring options to this downside and that features the potential partnership with low-earth orbiting, high-speed bandwidth connecting satellite tv for pc networks. I might predict both a deep partnership or acquisition of considered one of these firms within the close to future, as that is vital to John Deere’s future autonomous roadmap.

On the second day of the occasion, John Deere hosted the media at its new Austin check farm about 40 miles northeast of downtown. On the farm, we have been allowed to see, contact and journey on all the tools in operation at a number of demo stations across the property. The firm bought the property in Texas in order that testing of recent expertise can occur 12 months out of the 12 months, and preserve tempo with the accelerating expertise innovation curve in AgTech.
