RTK Robot Mower Solution — Boundary-free Lawn Mower Robot PCBA
SOLUTION DEFINITIONA robot mower solution centers on RTK (real-time kinematic) satellite positioning fused with vision and inertial navigation to deliver boundary-free planned mowing with multi-layer safety protection — the upgrade path replacing buried-wire mowers. MJX provides the complete ODM stack from controller and drives to positioning algorithms, plus second-source cooperation.
Pain Points We Solve
- The lawn-care economy is booming; boundary-free mowers are the next robot-vacuum-scale category
- RTK + sensor-fusion navigation demands a large in-house team to build
- Blade safety is regulated (EN 50636) — failing certification blocks the market entirely
- Grass load varies wildly; matching powertrain to runtime is a hard engineering problem
Key Features

FAQ
Does RTK work in tree-heavy yards?
Yes. RTK+vision/IMU fusion switches to gap-filling under canopy; typical gardens (30% occlusion) still achieve 98%+ coverage. For heavy shade, dual-base or vision-enhanced options are recommended.
Can the mower share a platform with your pool robot?
The foundation layer (RTOS, FOC, app framework) is shared while upper algorithms are independent — significant cost amortization for clients developing both.
How do you handle safety certification?
Safety logic is designed to EN 50636-2-107 (lift e-stop, tilt guard, proximity sensing) with a built-in certification checklist; we support notified-body submission with a strong first-pass record.
Is algorithm licensing available?
Yes. Brands with in-house hardware teams can license the positioning/planning stack with support, priced per project or per unit.
How compact can the mower be?
The platform fits 18cm-deck compacts with a controller down to 80×60mm; smaller forms are assessed jointly with your mechanical team.
