Smooth G1 is a robot system for leveling and troweling concrete in floor construction. The Floor Leveling Robot is equipped with automatic navigation, automatic walking, and laser leveling to obtain high-precision ground leveling. After the initial setting of the concrete, the Floor Troweling Robot goes to work, planning its path and then automatically positioning and walking it to carry out the troweling. The whole process from leveling to troweling only requires one person to handle the auxiliary work.
