How it works on your site

The Four-disc Concrete Pavement Troweling Robot from Fangshi Robotics (China) is a battery-powered machine that rides on its four troweling discs, steered by remote control within 200 m, and trowels fresh concrete floors before final set. Chinese national press and a Chongqing government news site describe a 四盘地面抹光机器人 troweling slabs on contractor sites in Shenzhen and Chongqing in 2024 and 2025, as the last of three robots after a laser screed and a crawler smoothing robot; none of those reports names the maker. Fangshi publishes no product status, its product pages carry the robot in captures from 2023 to 2026, and it is also sold by ProBuild Robotics (US).
