Exploring the Future of Robotics in Agriculture

We are opening an exploratory programme in field robotics for UK arable farming. It brings crop sensing, edge intelligence and precision intervention into one modular platform — the same approach that took SPARK from point of sale to a working robot fleet.

Why agriculture

From Crop Intelligence to Physical Action

SPARK has spent more than a decade on systems that read
what is happening in a venue and then do something about it
— sensing, decisioning and a fleet of 15+ robots operating
alongside people every day.

Arable farming poses the same problem in a harder
environment. Data on crop health is increasingly available;
acting on it precisely, at scale and at the right moment is not.
That gap is where we are directing our research.

Robotics

Autonomous platforms in unstructured ground

Sensing

Plant-level spectral, RGB and depth capture

Edge AI

Inference without reliable rural connectivity

Precision intervention

Controlled dosing at zone or plant scale

Initial research focus

Potato crop health

Potatoes give us a demanding first case: high input costs, disease pressure that rewards early detection, and row geometry a ground platform can
work within.

Concept under research

Autonomous base

Tracked, narrow-gauge, sized to travel between established rows.

Sensor mast

Adjustable height so capture geometry holds as the canopy develops.

Spectral, RGB and depth sensing

Three views of the same plant: colour, stress signature and structure.

Edge AI compute

Diagnosis on the machine, so a decision does not wait for a signal.

Precision intervention module

Interchangeable head — the platform's first modular pathway.

Technology architecture

Five layers under investigation

Autonomous mobility

Navigation, path planning and obstacle handling on soft, uneven ground.

Multimodal sensing

Fusing spectral, RGB and depth streams into one plant-level record.

Edge AI

Models small and fast enough to run on the machine, in the field.

Precision intervention

Controllable geometry, flow and dose — measured, repeatable application.

Field intelligence

A season-long record of what was seen, decided and applied, zone by zone.

Placeholder for field photography. Imagery to be supplied — no live trial sites are pictured.

The proposition

Sense → Diagnose → Decide → Act

Four stages, one loop. Each one has to work before the next is worth building, which is how the research is sequenced.

Sense

Multimodal capture at plant level — spectral, RGB and depth, geo- referenced row by row.

Diagnose

On-board models look for early stress signatures and separate crop from weed, plant by plant.

Decide

Treat, dose, irrigate or leave alone. Agronomist rules stay in the loop and remain auditable.

Act

A targeted physical intervention at the zone or plant, then measured again on the next pass.

R&D roadmap

Six phases, in order

Each phase has to produce evidence before the next begins. No dates are
committed while the work is exploratory.

Observe

Capture field data across a season to learn what is actually visible.

Understand

Label, model and test whether early stress can be separated from noise.

Decide

Turn diagnosis into agronomist-approved, auditable decision rules.

Intervene

Trial precision application through the first crop-care module.

Validate

Independent measurement against conventional practice on the same ground.

Scale

Only if the evidence supports it: more modules, more crops, more sites.

Why it matters

Doing more with less, measured properly

We are not claiming to change farming. We are testing whether a sense- and-act platform can make three specific things measurably better.

Input efficiency

Applying water, nutrient and treatment where a measurement says it is needed, rather than uniformly.

Earlier detection

Catching crop stress sooner gives a grower more options and smaller interventions.

Repeatable field work

Consistent, recorded passes through the crop, in a sector under real labour pressure.

How we work

Built Through Collaboration

We do not intend to do this alone. The programme is structured
around five kinds of partner, each holding knowledge we need.

Universities

Plant science, robotics and machine-learning research capacity.

Growers

Real field conditions, operating constraints and honest priorities.

Agronomists

The decision rules any autonomous system has to respect.

AI researchers

Model design and validation for constrained edge hardware.

Engineering partners

Mechanical, hydraulic and manufacturing expertise.

In collaboration with the National Edge AI Hub Further institutional partners will be named only once formally agreed.
