Open rectangular frame
Spans the façade bay. Uniform triangular guide rails carry and locate the tools along the frame.
AeroFaçade Robotics · Singapore · Concept stage
Smart Gondola.
Coordinated robotic swarms.
An open frame with triangular guide rails, wall-facing tools that wash, paint and make simple repairs, and a collector that follows the façade. Operators supervise from the roof or the ground.

Vision
To entirely eliminate human work-at-height risk and redefine high-rise façade maintenance through smart, zero-exposure robotic systems.
Mission
We pioneer autonomous digital-twin ecosystems for high-rise buildings, integrating smart-axis rail systems and modular robotics to automate end-to-end façade surveying, repair, cleaning, painting and quality audits.
The system
Four modules on one suspended platform.
Wall-facing robotic tools
Brush, roller and nozzle heads ride the frame facing the wall and work the mapped surface as a swarm.
Contour-adjustable collector
Supported by the gondola, it follows the façade as its depth changes and captures wash-water at the wall.
Roof unit and supervision
Power, water and paint by umbilical from the roof. Operators approve the plan, watch live footage and hold the emergency stop.
On the building
Everything heavy stays on the roof.
A roof unit supplies power, water and paint by umbilical. Twin hoists on standard outriggers index the frame floor by floor, so the work cell is designed to stay within the mass budget of ordinary rigging, with no crane.

Operating cycle
Survey. Clean. Paint. Verify.
-
A
Survey and map
A multi-sensor scan builds the digital twin. The system proposes robot allocation and paths; the operator approves.
-
B
Clean and repair
Brushes with a fine mist; the collector captures wash-water at the wall. Simple defects rectified before painting.
-
C
Paint
Nozzle held square to the wall. Valves cut the spray at mapped edges, so windows and accents need no tape.
-
D
Verify
Visual and thermal audit flags misses and runs. A service log per level goes to the building owner's records.

Safety
Human-supervised, not unmonitored.
People stay off the platform
In the operating concept, operators rig, assess, watch live footage and hold wireless emergency stops. Exclusion zones, barricades and catch-netting stay in place.
Certification path
Hoists, ropes, locks and frame are to be submitted for Professional Engineer endorsement and MOM equipment certification before any pilot, with operations under the WSH Act and Work-at-Height Regulations. This is a Phase 1–2 milestone; it has not been obtained yet.
Planned mechanical and electronic overrides
Overspeed brakes, slack-rope switches that cut hoist power, and a battery-driven controlled descent on power loss are specified in the concept design.
Environmental controls
The design captures wash-water at the wall and filters it before discharge, and uses overspray shrouds to limit drift to neighbours.
Roadmap
Concept to fleet in four phases.
-
Phase 0 · Now
Concept
Architecture decision, tool-force budget, bench test of the frame and localisation.
-
Phase 1
Full-scale prototype
One gondola level with hoists and positioning; mapping and masking pipeline; first cleaner module.
-
Phase 2
HDB block pilot
Equipment certification; one Town Council, one contractor; clean, paint and verify one elevation.
-
Phase 3
Commercial fleet
Lease and service contracts, multi-block programmes, regional partners.
Phase durations are indicative and will be confirmed by the team.
