Making advanced tech accessible for smart home robotics
The once-common Sunday hum of traditional lawn mowers is becoming a thing of the past. For years, robotic lawn mowers have struggled to win over homeowners with large or complex yards.
In 2025, Segway, a globally recognized leader in micro-mobility solutions, stepped into the garden market with a bold vision: create a robotic mower that could master any terrain, no matter how big or challenging. The result was Navimow, one of the most sought-after brands in the market. True to its name, the device excels at navigating and maneuvering with astounding precision around complex yards using ST’s advanced GNSS positioning technology.
Challenge
- Create a lawn mower that can precisely determine its position and navigate smoothly across any terrain, regardless of size or difficulty.
Solution
- ST’s Teseo GNSS positioning receivers, a GNSS technology initially designed for automotive applications and adapted by ST for the consumer market
Impact
- The launch of the X3 series made Segway Navimow one of the most sought-after brands.
Navigating the lawn with surgical precision
Lawn care might seem simple, but for a robot navigating a yard, the challenges are anything but. The ground itself presents a complex mosaic: uneven terrain with slopes and dips, patches of thick grass interspersed with flower beds, hidden roots, sprinkler heads, or garden hoses to name a few. These natural and architectural features create signal blind spots that can confuse even the most sophisticated lawn mowers. This is where ST’s Teseo GNSS positioning receivers became indispensable for Segway Navimow’s newest product, the X3 series, enabling it to precisely locate itself in the garden’s dynamic, and sometimes complex environment.
“
With ST, our lawn mower performs
with a level of accuracy once unimaginable
in consumer robotics.”

How ST brought automotive GNSS to consumer robotics
ST’s Teseo GNSS modules have long guided vehicles. In 2025, this same advanced technology has been thoughtfully adapted and made accessible to the smart home robotics segment. Working closely with ST, Segway equipped its flagship robotic lawn mower, the Navimow X3 series, with an innovative ST chip that connects 20 to 30 percent more effectively to satellite signals than traditional GNSS systems. This enhanced connectivity allows the lawn mower to navigate seamlessly through challenging environments—whether weaving beneath tree canopies or maneuvering near fences—where conventional GNSS often falls short. Paired with sensors and AI, the Navimow X3 series can recognize and avoid over 180 common yard obstacles ensuring safe, efficient, and worry-free lawn care.
Innovation grows best when supported
When Segway faced complex GNSS integration challenges during the Navimow series’s development, ST’s experts responded swiftly, collaborating closely to troubleshoot and resolve integration issues without derailing the product timeline. This level of support is backed by ST’s extensive experience in the most demanding applications such autonomous driving, where precision and reliability are non-negotiable. The same rigor and innovation that guide autonomous robot-taxis are now driving Segway’s robotic lawn mowers, underscoring the transformative potential of this partnership.
“
ST goes beyond hardware,
they empower companies with
the support they need to succeed.”
