Two patents.
One vision.
Facade robotics, reinvented.

FacadeBot is an autonomous facade renovation system: two specialized robots on a temporary rail frame replace the most expensive and most dangerous part of facade work — the human on the scaffold. No scaffold. No workers at height. 85% lower lifecycle cost. 7.2 month payback.

Chapter 02 · The market reality Source: BVMB · IBISWorld · WHO

Facade renovation in Germany alone is a €12 billion market. Built on scaffolds, manual labor and risk.

Three numbers describe what every owner of a multi-storey building knows. Three numbers describe what FacadeBot replaces. Both with verifiable sources, not from a marketing deck.

Chapter 03 · Two patents US Provisional · DPMA · PCT-ready

Two specialized robots. One shared rail frame. Filed as two independent inventions.

Patent A solves the surface preparation problem — grinding, vacuuming, crack filling under closed-loop force control. Patent B solves the painting problem — autonomous CMYK on facade scale with digital-twin window recognition. The rail-frame substrate is the common physical platform; the two robots are commercially independent.

A
US Provisional + DPMA · 20 Claims

Surface preparation robot with closed-loop force grinding.

A 3-axis robot traverses a temporary rail frame attached to the building. A force-controlled tool head executes grinding (PID 1 kHz, ±0.05 N), HEPA-filtered dust capture (99.97% quartz dust), automated crack detection via OpenCV and direct crack filling — all without scaffold, all without workers at height. The novelty is the kinematic combination: rail-frame substrate + force-closed-loop grinding + integrated dust capture + automatic crack workflow.

  2. C7Integrated tangential vacuum hood with HEPA-H14 filtration achieving ≥99.97% capture of respirable quartz dust at the abrasion site.
  3. C12Vision-based crack detection using OpenCV pipeline executing in real-time on the moving carriage, followed by automated electric crack-filling tool head in a single traverse.
  4. C18Force-control loop achieving ≥1 kHz update rate and ±0.05 N resolution via combined load-cell and motor-current signal fusion.
B
US Provisional + DPMA · 17 Claims · 30 total

Autonomous facade painter with 6-channel CMYK at building scale.

The same rail-frame substrate carries a second tool head equipped with an airless painting system and a 6-channel color valve manifold. A LIDAR + stereo-camera pair builds a digital twin of the facade, automatically masking windows, doors and ledges. A CMYK separation pipeline with Floyd-Steinberg dithering at 5 mm grid enables one-color coatings up to photorealistic murals — both addressed by the same claim set.

Claim-Highlights (auszugsweise)
  1. C1Robotic system for autonomous facade painting carried by a temporary rail frame, comprising a 6-channel valve manifold for CMYK+ separation and an airless atomization head.
  2. C4LIDAR-derived digital twin of the facade, automatically defining no-paint zones around openings (windows, doors, ledges) prior to motion plan execution.
  3. C9Floyd-Steinberg error-diffusion dithering at building scale with a configurable grid pitch (default 5 mm), producing photorealistic image reproduction directly on the facade.
  4. C15Closed-loop registration between consecutive paint passes via ArUco fiducials affixed to the rail frame, enabling sub-pixel multi-pass alignment.
Chapter 04 · The numbers 5-year TCO · payback · throughput

Four numbers that move the investment thesis.

Lifecycle cost dominates facade economics. Scaffold, labor, downtime and accident cost compound for 25 days. FacadeBot replaces all four cost drivers simultaneously.

Why this isn't easily copied.

Four overlapping layers of defensibility — IP, capital cost of the engineering work, time on market, regulatory compliance. We have already spent the 18 months of work a competitor would have to spend after the patent grant.

Patent A (Surface Prep) and Patent B (Painting) are independently licensable. Loss of one doesn't sink the other. Both filed US Provisional + DPMA, PCT-ready inside the 12-month priority window.

One inventor. Eighteen months of work. Looking for the right partner.

“ I built the system that I wished existed when I watched my neighbours' building get scaffolded for the third time in a decade. Manual facade work is the most expensive, most dangerous part of construction, and nobody had solved it properly. FacadeBot is the result of asking why not. ”
