STMicroelectronics has partnered with Segway to enhance its latest range of robotic lawnmowers. The collaboration integrates precision positioning and extended satellite-signal coverage, designed to improve operational efficiency and safety.
Reliable satellite navigation is essential for robotic lawnmowers that operate without boundary wires. These devices must autonomously navigate safely, even in areas where tall buildings or trees obstruct satellite signals. Uninterrupted satellite signal coverage is critical for functioning at the edge of stairs or steep slopes.
STMicroelectronics’ Teseo satellite navigation chips — with automotive-grade quality and reliability — are well-suited for robotic lawnmowers. These chips enable decimeter-level location accuracy, ensuring the mower remains within its designated field perimeter.
Segway’s recently launched Navimow X3 robotic lawnmowers incorporate ST’s Teseo V single-chip triple-band GNSS receivers. These receivers track multiple satellite constellations simultaneously, delivering superior performance in challenging environments. The real-time kinematic (RTK) technique further corrects satellite signal errors, ensuring stable operation in complex layouts such as properties with narrow passageways or multiple mowing zones. The company said that compared to earlier models, Segway reports a 20 to 30% increase in satellite signal coverage with ST’s technology.
Technical specifications include ST’s STA8135GA GNSS receiver from the Teseo V family. This automotive-qualified chip integrates triple-band positioning measurement and dead-reckoning features within a compact package. On-chip voltage regulators simplify power supply selection, further enhancing design efficiency.
