The High Precision Flooring R&D team designed the fully automated floor grinding robot with an innovative design that uses movable grinding discs and introduces external references as a reference. After the user has completed the initial planning of the work area and rapid deployment, the robot can plan the path in the work area by itself and automatically adjust the grinding disc to achieve the finished product's elevation and flatness control for the finished floor by relying on the external reference, without human intervention during the operation. At the same time, the robot itself is equipped with a dust collection system that will minimize the dust during operation and take care of users' health.
