03 / SUPERVISED OPERATION

Demonstrate a blocked lane and an explicit operator restart.
Simulation only · no hardware connection
At least two points. Crop and boundary checks remain active.
Return home reverses along the recorded trail. Obstacles remain active; no shortcut is assumed.
DECISION STUDY / SAME FIELD · SIX SCENARIOS
Which operating strategy meets your requirement?
Compare two turning methods at three speeds. The fastest mission is only useful if it meets the tracking and clearance limits.
Scenario assumptions, not a supplier quotation. The study starts fresh and excludes live interruptions.
01
A route comparison you can interrogate.
Test mission time, row-time share, tracking error and clearance using the same field geometry and controller.

Row-time share is moving time on row segments divided by total mission time. It is not measured field efficiency or hectares treated.

What the model calculates
Pure pursuit generates a curvature command from a point ahead on the route. Acceleration and heading-rate limits govern the integrated motion; the robot is never snapped to the centreline.
κ = 2 sin(α) / Ld
ωL,R = (v ∓ Ωb/2) / r
ωL,R = (v ∓ Ωb/2) / r
Headland screening uses turn radius plus the circular body envelope and margin. Crop and field clearance are checked against the oriented rectangular body during the mission.
What the results mean
This is a deterministic planning scenario with ideal rolling, flat terrain, known obstacles and surveyed position. The four-wheel rover is approximated as differential drive. Soil slip, GNSS error, perception uncertainty, terrain forces and implement performance are not modelled.
A passing scenario is a candidate for a controlled field trial. It is not a safety certification, a validated throughput forecast or a substitute for measured platform parameters. Pivot manoeuvres may disturb soil; that effect is not quantified here.
