Summary

The WEIBUILD PNP-3000iC is a battery-powered, wheeled interior spraying robot with a front-mounted 4-axis arm on a lift and traverse axis. It sprays putty (joint compound), latex paint, primer, and water-based coatings on interior wall and ceiling surfaces up to 3.2 m working height; sanding, taping, and exterior work stay with the crew. The PNP-3000iC has been shipping since 2023, with a 3-year centralized procurement contract from Singapore's Housing & Development Board and demonstration deployments in the UAE and Taiwan.

How it works on your site

Finishing (Second and Third Coats)

The robot sprays primer and two topcoats from the same mechanical platform used for putty application. The front-mounted 4-axis arm handles walls and ceilings; taping, corner work, and surface preparation remain crew tasks.

Skim Coating (Level 5 Only)

The 4-axis arm sprays one or two coats of putty while built-in tilt compensation maintains constant nozzle-to-wall distance during vertical movement. Coating thickness uniformity is within 0.1 mm deviation (vendor-stated). The PNP-6000iC variant reaches 5.9 m for commercial ceiling heights that the 3000iC cannot cover.

Painting

The robot paints a complete residential flat without worker supervision. A separate modeling robot scans the room and generates the spraying program; the PNP-3000iC then executes the plan autonomously, including navigation between work points.
