02 / HOW IT WORKS

Component by component.

01

The Multi-Spectral Vision Bar

A quad-camera array spanning the gantry. Combines RGB, near-infrared and chlorophyll fluorescence to estimate sugar density and skin firmness. Decides ripe/not-ripe per fruit in under 60 ms.

SPECS

  • Cameras4 multi-spectral
  • Decision<60 ms / fruit
  • ChannelsRGB + NIR + ChlF
  • Crops trained5 primary
02

The Soft-Pneumatic Grippers

Twenty independently actuated grippers using food-grade silicone fingers. Each finger applies a calibrated 0.4 N, gentler than a human hand. Pressure feedback prevents bruising on overripe fruit.

SPECS

  • Grippers20 parallel
  • Force0.4 N
  • MaterialFood-grade silicone
  • Cycle1.2 s
03

The Sorting Conveyor

Internal three-lane belt routes every picked fruit by grade in real time. Each lane terminates in a labelled bin: MARKET, PROCESS or COMPOST. Sort decision uses vision data and per-fruit weight.

SPECS

  • Lanes3
  • Throughput240 fruit/min
  • MaterialFDA belt
  • Wash cycleDaily, on-machine
04

The Gantry Arm System

Telescoping boom adjusts row width from 0.8 m to 2.4 m. Height adjusts from 0.4 m to 2.0 m to clear tomato vines, strawberry beds and coffee bushes alike.

SPECS

  • Width0.8 – 2.4 m
  • Height0.4 – 2.0 m
  • Adjust time<2 min
  • DriveServo + lead screw
05

The Removable Bins

Three labelled bins clip out of the chassis in under 10 seconds. Each holds 25 kg of produce. Cooperative receives a WhatsApp ping when a bin is 80% full.

SPECS

  • Bins3
  • Capacity25 kg each
  • Swap<10 s
  • MaterialFood-grade PP
06

The 48V Powertrain

Same shared-platform 48V architecture as KILIMO-1. Four soft-pneumatic wheels run between row spacings without compacting beds. Total continuous output: 9kW.

SPECS

  • Voltage48 V
  • Wheels4 soft pneumatic
  • Continuous9 kW
  • Battery48 V · 5 kWh
07

The Per-Fruit Data Logger

Logs ripeness, grade, weight, GPS position and timestamp for every fruit harvested. Exported as CSV via WhatsApp. The first time most cooperatives have ever held per-fruit data.

SPECS

  • Fields8 per fruit
  • ExportCSV via WhatsApp
  • Buffer60 days
  • PrivacyCooperative-owned
08

The WhatsApp Interface

Same WhatsApp-first command surface as the rest of the fleet. "Harvest tomato, greenhouse 2." Replies include progress, photos, per-grade tonnage and bin status.

SPECS

  • TransportWhatsApp + SMS
  • Languages5
  • MediaText · photo
  • Onboarding<45 min
09

The Repair-First Construction

Identical service philosophy to KILIMO-1. Bolt-on panels, metric fasteners, sourceable connectors, no proprietary tools.

SPECS

  • FastenersMetric standard
  • Max wrench13 mm
  • PanelsBolt-on
  • FinishPowder-coated
10

The Safety System

LiDAR-based pedestrian detection, side-mounted E-stops, remote kill via WhatsApp, and a gantry interlock that disables grippers whenever the boom is in service position.

SPECS

  • Sensors2× LiDAR
  • E-stops2 + remote
  • InterlockGantry-aware
  • AlignmentISO 18497

03 / A DAY IN THE FIELD

From command to report.

STEP 01

Command

Cooperative manager messages MAVUNO-7: "Harvest tomato, greenhouse 2."

STEP 02

Position

Machine drives to field entry, raises gantry to crop row height.

STEP 03

Scan

Vision bar scans each plant, mapping every fruit.

STEP 04

Pick

Grippers descend, picking only ripe fruit, sorting by grade.

STEP 05

Route

Conveyor routes each fruit to MARKET, PROCESS or COMPOST bin.

STEP 06

Swap

When a bin fills, machine signals cooperative to swap empty bin.

STEP 07

Report

Final WhatsApp report: total kilograms, per-grade breakdown, per-fruit data export.

06 / ENGINEERING PRINCIPLES

What guided this machine.

  1. 01Treat every fruit as though it were sold tomorrow.
  2. 02Soft pneumatics over hard mechanics where contact meets crop.
  3. 03Sort before storage. Storage decisions cannot be undone.
  4. 04The cooperative owns the data its harvest creates.
  5. 05Wash, service and repair without leaving the field.
