Indoor Coating Robot NP320

Measure the ceilings of the world's housing and one number keeps answering: just under three metres. The standard residential storey — the apartment, the hotel room, the ward, the office bay — is humanity's most mass-produced space, built in the millions every year to heights the span of 2.4 to 3 metres covers almost entirely. The BMR Indoor Coating Robot NP320 is a machine dimensioned to exactly that fact. Its name is its reach: a floor-standing, battery-powered spraying robot that coats to 3,200 millimetres in a single pass from the floor — clearing the world's most common ceiling with margin to spare — and its intelligence is its routing: automatic path planning that reads the room and drives its own coverage across every surface a standard interior presents. The surface list is where the machine shows its finishing-trade literacy: not just walls and ceilings but bay windows, beams and gypsum lines — the recesses, downstands and plasterwork details where roller crews slow down and quality disputes begin — sprayed with primer, emulsion paint and topcoats at the constant rate only a machine holds from the first room of a tower to the four-hundredth. As the entry machine of BrightMaster's interior-decoration line, the NP320 is deliberately the simple one: site labour loads its material and moves it between rooms, which keeps the investment light and the operation familiar — and when a contractor's volumes outgrow that arrangement, the self-feeding, self-transitioning NP320 Pro waits on the same platform, one trim up.

The Indoor Coating Robot NP320 is available for purchase internationally through this page, with delivery, customs clearance and after-sales support arranged for buyers across Europe, the Americas, the Middle East, Asia-Pacific and worldwide.

Background

Why 3.2 metres is a strategy, not a ceiling

Interior coating robots face a design fork: build tall for the halls and lobbies, or build for the storey and win on volume. BMR's line answers both ways — its P-series Intelligent Coating Robot reaches 6.5 metres for the atria and hospitals — but the NP320 takes the volume side on purpose, because that is where the square metres live. Residential towers, hotels and standard offices are repetitive-room machines: hundreds of near-identical spaces whose economics reward a compact base that rolls through doorways, sprays a full room from the floor without masts or platforms, and repeats without fatigue. Independent comparisons of the interior-spraying field place the NP320 among the credible floor-standing systems globally for exactly this profile — repetitive apartments, hotels, offices and hospitals — with its honest boundary stated just as plainly: rooms taller than its spray height, and floors too cluttered for a mobile base, belong to other tools. Within its territory, which is most of the built world, the dimensioning is the advantage.

The first robot of the fit-out

Shenzhen BrightMaster Robotics — intelligent construction's market-share leader, global exclusive agent of the Bozhilin portfolio, with more than 5,200 robots delivered across 1,600-plus projects and over 40 million square metres built in 13 markets — positions the NP320 as the approachable front door of an interior fleet that has already worked internationally, including a multi-robot renovation deployment in Singapore. In the coordinated workflow, the putty grinding robot prepares the surfaces the NP320 will coat, the measuring robot verifies both the geometry before and the finish after, and the construction hoist moves the machines between storeys — with the NP320's role being the one every fit-out ultimately pays for: film on the wall, even, complete and on schedule. For many contractors it is the first construction robot they buy, precisely because its trade is the one they subcontract most and its operation asks the least: charge, load, position, start.

Technical Specifications

BMR publishes the NP320's full parameter table — productivity, hopper capacity, battery endurance and dimensions — through its datasheet channel; figures are confirmed against the current datasheet at quotation, and material compatibility by specification or sample testing.

What does machine spraying change in a standard room?

The last metre and the thousandth room. In a 2.7-metre room, a human sprayer's enemies are the edges of ergonomics: the ceiling band worked overhead on stilts or steps, the bay-window returns and beam soffits that break rhythm, the gypsum lines where a wavering pass reads instantly in raking light. The NP320 works that geometry from a stable base at machine-constant standoff and speed — the parameters that decide film build, and with it coverage, opacity and drying behaviour — so the detail that slows a crew is simply another waypoint on the path plan. The second change is statistical: finish quality across a tower is a distribution, and manual work widens it with every fatigued afternoon, while a path-planned machine lays the same film in room four hundred as in room four. For developers, that narrows snagging and repaint rates where they cost most — at handover scale; for painting contractors, it converts their most repetitive scope into supervised machine time and redeploys skilled hands to the cutting-in, touch-up and judgment work machines still can't price.

Who is the Indoor Coating Robot NP320 for?

For painting and finishing contractors serving residential towers, hotels and serviced apartments — the repetitive standard-height interiors the machine is dimensioned for; for general contractors and developers whose fit-out schedules hinge on painter availability and whose warranties hinge on finish consistency; for hospitals, schools and office builders coating long sequences of similar rooms and corridors; for renovation specialists rolling room-by-room programmes of the kind BMR's interior fleet has served internationally; and for contractors making their first construction-robot purchase, where the NP320's familiar operating model — site labour feeds and positions it — keeps adoption simple. Buyers whose volumes justify unattended production should look one trim up to the NP320 Pro; buyers whose ceilings exceed the spray height, to the 6.5-metre P-series platform beside it in the line.

What is the Indoor Coating Robot NP320 used for?

1. Apartment and residential spraying: primer and paint across repetitive standard-height rooms at tower scale.
2. Hotel and hospitality fit-out: consistent wall and ceiling finishes through long sequences of similar rooms.
3. Office and commercial interiors: constant-rate coating of bays, corridors and standard storeys.
4. Healthcare and institutional projects: uniform, machine-applied finishes in wards, classrooms and public rooms.
5. Detail-surface coating: bay windows, beams and gypsum lines sprayed at machine-steady standoff.
6. Coordinated fit-out workflows: the coating stage between putty grinding and measurement in BMR's interior fleet.

Pricing and Availability

The Indoor Coating Robot NP320 is available for purchase and international delivery through this page, as a single machine for a painting contractor, in multiples for parallel tower coverage, or within BMR interior packages alongside the putty grinding and measuring robots — with the NP320 Pro quoted alongside where self-feeding, low-supervision production fits the volumes better. Price and cost depend on configuration, consumables and wear-part provisioning, training and commissioning scope, and quantity, so buyers should request a current quotation for their project profile, which also confirms the full engineering datasheet; delivery, customs clearance and after-sales support are arranged worldwide. Purchase enquiries, datasheets and availability details for the NP320 are available on this page.

Frequently Asked Questions

What is the BMR Indoor Coating Robot NP320?

BrightMaster Robotics' floor-standing interior spraying robot: a battery-powered base with automatic path planning that applies primer and paint across walls, ceilings, bay windows, beams and gypsum lines at spraying heights up to 3,200 millimetres — the entry machine of the company's interior-decoration line.

Why is its height limit 3.2 metres?

Because that is the dimension of the standard storey: the overwhelming majority of residential, hotel, office and healthcare rooms sit under 3.2 metres, and sizing the machine to that reality keeps it compact, doorway-mobile and economical — with BMR's 6.5-metre P-series platform covering the halls and atria above it.

Which surfaces and materials does it handle?

Interior walls and ceilings plus the detail geometry that slows manual crews — bay windows, beams and gypsum lines — using primer, emulsion and latex paints and compatible water-based topcoats on properly prepared cement-based or plastered surfaces.

How autonomous is it?

Within the room, fully: automatic path planning drives its coverage without manual guidance. Between rooms and refills it relies on site labour — the deliberate simplicity of the entry trim — while the NP320 Pro above it adds automatic material feeding and same-layer transitions for unattended production.

How does it fit BMR's robot workflow?

As the coating stage of the coordinated interior fleet: the putty grinding robot prepares its surfaces, the measuring robot verifies geometry and finish in the closed quality loop, and the construction hoist handles vertical logistics across the project.

Who builds it, and is the line proven?

Shenzhen BrightMaster Robotics — the industry's market-share leader and exclusive global agent of the Bozhilin portfolio, with more than 5,200 robots delivered, 1,600-plus projects and over 40 million square metres built, including international interior deployments such as a multi-robot renovation project in Singapore.

Where can I buy the Indoor Coating Robot NP320 and what does it cost?

The NP320 is available through this page, with delivery, customs clearance and after-sales support arranged for buyers worldwide. Because cost varies with configuration, consumables and quantity, buyers should request an individual quotation — which also provides the current full datasheet. All purchasing details are available on this page.

Summary

The NP320 is the coating robot built to the dimensions of the world as it is actually constructed: 3.2 metres of single-pass reach for the standard storey, a battery base that rolls through ordinary doorways, path planning that treats beams, bays and gypsum lines as waypoints rather than problems, and an operating model simple enough to be a contractor's first robot. In the repetitive-room economy of towers, hotels and hospitals — where finish quality is a statistic and schedules are painted one identical space at a time — it converts the fit-out's biggest scope into machine consistency, with the Pro trim and the 6.5-metre platform waiting in the same line as ambitions grow. For the rooms the world builds most, this page is the starting point.
