Sunstone Launches MR50: All-in-One Mowing and Transport Robot for Challenging Outdoor Terrain

The MR50 stands out for its human-following intelligence, robust build and flexible modular design, bringing tangible improvements to on-site workflows. Its flagship real-time intelligent following system maintains a 1-meter safe distance behind field operators. Rather than constant manual remote manipulation, the robot autonomously trails workers to execute mowing and hauling assignments, effectively easing operator fatigue and cutting labor reliance. Operators can also take over remote control within a 200-meter radius. A physical one-touch emergency-stop button is equipped to mitigate risks amid unexpected working conditions.

Modular swappable batteries enable non-stop continuous operation and minimize downtime. The detachable, extendable cargo rack and heavy-duty tow hitch (max towing capacity 100 kg) further expand task diversity. Constructed with industrial-grade components and an optimized mechanical layout, the MR50 simplifies routine inspections and part replacements, delivering reduced long-term maintenance expenses. It consolidates mowing and material transportation into one single device, eliminating investments in multiple separate pieces of equipment.

Weighing 148 kg, the tracked robot can negotiate slopes up to 30°, supported by 100 mm-wide rubber tracks for stable traction on rough surfaces. Power is supplied by a PSE-certified 48V 30Ah lithium-iron-phosphate battery. It delivers 4-6 hours of runtime under transport or following mode (subject to payload weight), and 2-4 hours in mowing mode, subject to speed settings. Dual 300 W brushless motors propel the chassis, with adjustable travelling speed ranging from 0-3 km/h.

The 3 kw high-output cutting motor drives hardened-steel rotary blades. Its 500 mm cutting width supports adjustable cutting height between 20 mm and 150 mm, while motor speed can be tuned from 0-3000 r/min to adapt to varied grass conditions. The extendable cargo rack reaches a maximum dimension of 1350 mm × 1450 mm, with a maximum load capacity of 100 kg.

Engineered for complex field environments, MR50 fits a wide array of outdoor working contexts. It excels in orchard ground management and mountain-area mowing, where sloped and bumpy terrain creates obstacles for conventional lawn machinery.

Beyond agricultural uses, the robot handles farm-site material transportation and large-scale landscape upkeep. It also serves for vegetation and weed control at solar power plants, a typical site with scattered obstacles and undulating grasslands. The tracked chassis delivers consistent performance across these hard-to-navigate locations.

“Outdoor operation teams are frequently troubled by labor constraints and harsh terrain,” commented a Sunstone product spokesperson. “We developed MR50 around real-world field pain points. By combining smart follow-along robotics, powerful cutting performance and flexible transport capacity, it helps operators boost output with fewer manpower inputs.”

The MR50 marks a practical step toward electrified, labor-efficient outdoor robotic operations.
