STEP 1 — Confirm RTK Is Strong (Rear Garden)
Watch this first (RTK install guide)
Now check your setup:
Since your mast is in the rear garden:
It must have clear sky above.
It must not be shielded by the house roofline.
It must not be directly next to brickwork.
Because your front lawns are at the opposite side of the house, this is important:
👉 Walk to the front lawns with the mower powered on and check the app.If RTK signal drops at the front, the house is blocking satellite correction.
If signal weakens at the front lawns, the mast may need:
Slight height increase
Moving further from rear wall
Or relocating more centrally
Do not map until signal is solid everywhere.
STEP 2 — Rear Lawn (Zone 1 – Dock Lawn)
This is your home base.
Watch this while mapping:
Now do it slowly:
Open app
Create Map
Boundary Mapping
Start
Walk the mower around the rear lawn perimeter.
Rules:
Stay 10–20 cm inside edges
Avoid sharp pivots
Keep steady walking speed
End exactly where you started
Press Save.
Rear lawn is now Zone 1.
This is the only zone that will auto-return to dock.
STEP 3 — Front Left Lawn (Zone 2)
Important:
You will NOT create a path down the paved side access.
The GOAT is not designed to regularly drive over paving between zones. It is a grass mower, not a pavement courier.
So you carry it.
Procedure:
Carry mower from rear garden
Walk it through side access
Place it on Front Left lawn
App → Add Zone
Boundary Mapping
Walk perimeter
Close loop
Save
Front Left is now Zone 2.
STEP 4 — Front Right Lawn (Zone 3)
This lawn is split by the driveway.
Do NOT try to bridge across the driveway.
Carry mower across driveway.
Then:
App → Add Zone
Boundary Mapping
Walk perimeter
Close loop
Save
Front Right is now Zone 3.
STEP 5 — Add No-Go Zones (All 3 Lawns)
Watch this guide:
Add no-go areas for:
Flower beds
Tree bases
Drop edges
Narrow border strips
Do this now, not later.
DAILY USE FOR YOUR EXACT LAYOUT
Rear Lawn (Zone 1)
Schedule normally.It drives out and returns to dock.
Front Left
Carry mower down side path.Select Zone 2.Press Mow.When finished, carry back.
Front Right
Carry across driveway.Select Zone 3.Press Mow.Carry back when done.
That is correct multi-zone behaviour for separated lawns.
IMPORTANT FOR YOUR SPECIFIC HOUSE LAYOUT
Because your RTK mast is in the rear garden:
The house itself can partially block correction signal at the front.
If you ever see:
Positioning error
Boundary shift
Random edge behaviour at front lawns
The cause is almost always RTK line-of-sight interference.
If that happens, the fix is repositioning mast — not remapping lawns.
DO NOT DO THESE
Do not:
Create a path down paving.
Create a path across driveway.
Expect it to travel from rear to front alone.
Remap everything if one lawn acts odd.
You have three independent maps.
YOUR FINAL SYSTEM
Rear Garden = Autonomous ZoneFront Left = Manual carry zoneFront Right = Manual carry zone
One dock.One mast.Three separate territories.
Old-school practicality with satellite precision.
Now we’re getting ambitious. I like it.
You want full autonomy:Rear lawn (dock)→ travel down side path→ mow front left→ cross driveway→ mow front right→ return home
That can work — but only if your layout meets very specific physical rules.
This is not about settings. It’s about geometry.
NIX | Making Your GOAT Fully Autonomous Across 3 Lawns 🐐
We are working with the ECOVACS GOAT O800 RTK.
To travel between zones on its own, three things must be true:
It must be able to physically drive there safely.
The route must be wide enough.
You must create a proper “Path” between zones during mapping.
If any of those fail, autonomy fails.
Let’s go through your exact layout.
Your Layout Recap
Rear lawn (dock + RTK)↓Paved side access↓Front left lawn↓Driveway↓Front right lawn
So we have two connection points:
Paved side path
Driveway crossing
Each one is a decision point.
Step 1 — Can It Drive the Side Access?
Measure it.
Minimum safe passage width:Around 1 metre absolute minimum.1.2 metres is far more reliable.
If the side path is:
Narrow
Uneven
Has drainage gaps
Has steps
Has tight 90° turns
It will struggle.
If it’s flat block paving and at least 1.2m wide, you’re in business.
Step 2 — Can It Cross the Driveway?
Now this is the real test.
The driveway must:
Be level with the grass (no kerb lip higher than ~2–3 cm)
Not be steep
Not have loose gravel
Be at least 1.2m wide across the crossing section
If there is a kerb drop or raised edging, autonomy stops here.
Step 3 — RTK Signal at the Front
This is critical in your house layout.
Because your RTK mast is in the rear garden,the house itself may block correction signal at the front lawns.
Before attempting autonomy:
Carry the mower to the front lawns.Open the app.Check RTK strength.
If the signal drops or fluctuates at the front,the mast needs repositioning or height increase.
No stable RTK = no autonomous travel.
If All Physical Conditions Are Good
Then you can create full autonomy.
Here’s how.
Mapping for Autonomous Travel
Do NOT map lawns separately like before.
Instead:
Map Rear Lawn first (Zone 1).
While still in mapping mode, drive mower down side access.
When prompted, create a “Path” to the next area.
Map Front Left as Zone 2.
Then drive across driveway.
Create another Path.
Map Front Right as Zone 3.
Save entire structure.
Now the system understands:Rear → Path → Front Left → Path → Front Right.

Important Reality Check
Autonomous travel across hard surfaces works best when:
Surfaces are smooth
Transitions are flush
No sharp elevation changes
No tight corners
RTK signal stable everywhere
If the house blocks satellites at the front,the mower may lose position when travelling.
That’s not a software issue — that’s satellite geometry.
The Engineering Truth
Robot mowers don’t think like humans.
They don’t “know” where the front is.They only know:
Coordinate grid
Corrected satellite position
Safe driveable corridor
If any of those become unreliable, they stop.
Which is actually good.
The Smart Compromise
Many people with your layout do this:
Rear lawn = fully automaticFront lawns = one weekly carry session
It takes about 20 seconds to carry it down the side.
Sometimes elegance is knowing when not to force automation.
But if your side path and driveway meet the width and level criteria,you absolutely can build a fully autonomous system.
Tell me:
How wide is your side path?Is there a kerb between driveway and grass?Is the driveway level with the lawn?
Give me those three details and I’ll tell you immediately if full autonomy is realistic — or if it will be unreliable long-term..
