The Indoor Coating Robot NP320 Pro is a fully automated coating robot designed for interior walls, bay windows, ceilings and similar architectural elements, applying both latex paint and putty. It carries automatic path planning with BIM software, laser SLAM indoor navigation, automatic obstacle avoidance, intelligent monitoring and a dual-battery power management system; its main use is the interior renovation and construction of residential buildings, commercial offices, apartments and industrial plants. Unlike a basic paint spraying robot it focuses on broader indoor coating work: wall coating, ceiling coating and putty application.
BIM-based path planning builds the coating route from building information and reduces unnecessary repeated movement; laser SLAM navigation lets the robot locate itself and move accurately in a complex site environment. Total weight is 680 kg, dimensions 960 × 760 × 1750 mm, working height up to 3,100 mm and positioning accuracy ±30 mm. Output is 160 m² of latex and 60 m² of putty per hour, 3 to 4 times manual work; coverage exceeds 90 percent. The battery runs more than 5 hours and charges in under 2.5 hours; there is a 60 L bucket, 0.5 m/s speed, 30 mm obstacle and 50 mm trench crossing and a 10° climbing angle. With mobile spraying and dynamic pressure control it covers walls, corridors, ceilings, bay windows, beams, entryways and walk-in closets.

For projects where emulsion spraying output alone comes first, the NP320 is offered separately.
