## Overview and value chain

Markers: [EC: EU Machinery Directive 2006/42/EC & CAP | OECD: Agricultural Biotechnology | Regulator: ISO 18497 safety, OSHA (USA), EU Machinery Directive, MoA (China)]

Agricultural robotics and autonomous tractors are dedicated field machines
that replace labor and chemicals rather than merely make conventional
equipment precise. Carbon Robotics' LaserWeeder uses computer vision and
high-power lasers to kill weeds without herbicide, deployed across 15
countries and shown at the 2026 World Ag Expo; Monarch Tractor's MK-V is a
fully electric, driver-optional tractor (with California CORE subsidies up
to $68,750); FarmDroid's solar FD20 seeds and weeds for 18–24 hours a day
on 8 mm RTK-GPS precision across seven European countries; and EcoRobotix's
ARA 620 sprays plant-by-plant at 6×6 cm spots through 156 nozzles. This
category is the dedicated-robot counterpart to the precision-agriculture
variable-rate stack — where precision-agriculture-agritech executes
prescriptions on smart conventional machinery, agricultural robotics
deploys purpose-built autonomous machines.

The key directions of agricultural robotics are:
1. **Laser & mechanical weeding robots (Laser & Mechanical Weeding Robots):** computer-vision-guided lasers (Carbon Robotics) and mechanical tools (Naio, FarmDroid) that remove weeds without herbicide.
2. **Autonomous electric tractors (Autonomous Electric Tractors):** driver-optional, software-defined electric platforms (Monarch MK-V) that replace diesel labor with electrified autonomy.
3. **Ultra-precise spot-spraying robots (Ultra-Precise Spot-Spraying Robots):** plant-by-plant AI sprayers (EcoRobotix ARA 620) hitting 6×6 cm spots to cut chemical use.
4. **Autonomous-driving retrofit systems (Autonomous-Driving Retrofit Systems):** autonomous-driving kits that convert conventional tractors to unmanned operation (Zhongke Yuan Dongli).

#### Stage 1: Perception
Cameras (multispectral, RGB, 3D), lidar and RTK-GPS perceive crop rows, individual plants and obstacles; the output is a real-time sensor stream.

#### Stage 2: AI detection
Neural networks classify crop vs weed and identify the action target — Carbon Robotics in milliseconds, EcoRobotix plant-by-plant — producing weed/crop maps and tool actions.

#### Stage 3: Path planning
The robot plans its autonomous route across the bed or row using RTK-GNSS (FarmDroid at 8 mm precision) and lidar obstacle avoidance; the output is a safe navigation plan.

#### Stage 4: Tool actuation
The selected tool fires on target — Carbon Robotics' lasers, Naio's mechanical implements, or EcoRobotix's 156 spot-spray nozzles at 6×6 cm precision; the output is a weeded or sprayed field.

#### Stage 5: Unsupervised operation
The robot works a full shift unsupervised on solar (FarmDroid FD20, 18–24 h/day) or battery-electric (Monarch MK-V) power, executing the plan across the field.

#### Stage 6: Fleet management
As-applied maps, coverage logs and fleet status stream to a management platform (Monarch Wingspan AI, EcoRobotix RTK traceability), closing the loop with regulatory traceability under ISO 18497 and the EU Machinery Directive.
