The NIMBLER™ robots come in 2 sizes -- SMALL and MEDIUM.

The SMALL NIMBLER™ has a dimension of 190L x 110W x 90-120H mm with a weight of 600g; the MEDIUM NIMBLER™ is 320L x 220W x 150-220H mm with a weight of 1,500g.

Both sizes of robots have an operating time of ~45mins before needing a battery change.

No. NIMBLER™ does not replace statutory inspection requirements or the professional judgment of appointed engineers or competent persons.

It is a tool that supports inspection workflows by improving access, visibility, and documentation in constrained spaces. Final assessment, certification, and regulatory submissions remain the responsibility of the appointed professionals and building owners.

Regulatory acceptance is based on inspection outcomes, evidence quality, and professional accountability, not the specific tool used.

NIMBLER™ has been publicly showcased at two industry trade shows and featured in two industry sharing sessions organised by the Building and Construction Authority (BCA). These forums are typically attended by regulators, professional engineers, building owners, and industry practitioners, and are intended to surface emerging inspection approaches and technologies relevant to the built environment.

In practice, NIMBLER™ supports regulatory expectations by improving access to constrained spaces, enabling safer inspection workflows, and producing clearer, more consistent inspection records. Acceptance of inspection findings continues to rest with the appointed professionals and remains subject to applicable regulations, codes, and professional standards.

Adoption has been driven primarily by owners, engineers, and operators seeking safer and more complete access to concealed spaces, rather than by changes to regulatory requirements.

In many deployments, NIMBLER™ has eliminated the need for manual entry by providing reliable visual access to confined or obstructed spaces that were previously unsafe or impractical for personnel to enter.

The platform has enabled inspections in areas where human entry was not feasible due to clearance, safety, or operational constraints, allowing inspection teams to obtain meaningful visual information without exposing personnel to confined-space hazards.

Where inspection objectives can be met through visual assessment, NIMBLER™ can be used in place of manual entry. However, when physical intervention, tactile assessment, or remedial works are required, human entry may still be necessary and must comply with applicable safety and permit requirements.

NIMBLER™ is therefore best understood as a tool that reduces or removes the need for manual entry for inspection and scoping purposes, while supporting safer, more targeted decisions on when human access is genuinely required.

NIMBLER™ is designed to position itself in close proximity to inspection targets, even within tight, cluttered, or obstructed spaces. Its adaptive form and controlled movement allow the platform to approach areas of interest directly, rather than relying on distant or indirect views.

For situations where physical proximity is limited, NIMBLER™ is available in variants equipped with 4× zoom cameras, enabling detailed visual inspection without requiring contact or further access preparation. Selected variants also incorporate thermal imaging, supporting the identification of temperature differentials associated with moisture ingress, insulation issues, or abnormal heat patterns.

The combination of close-range positioning, optical zoom, and thermal sensing allows inspection teams to obtain meaningful visual and thermal information across a range of constrained conditions, while maintaining a safe and controlled inspection process.

NIMBLER™ captures inspection data through onboard visual and sensing systems designed for close-range assessment in constrained environments. Depending on inspection objectives, the platform can be deployed with different camera and sensor configurations to ensure meaningful data capture under varying access conditions.

Standard configurations include a high-resolution full-colour visual camera optimised for close-proximity inspection in low-light and confined spaces. Where physical proximity to the inspection target is limited, NIMBLER™ is available in variants equipped with a 4× zoom camera, allowing inspectors to examine fine details, such as cracks, corrosion, fixings, or surface degradation—without requiring additional access preparation.

Selected variants also incorporate thermal imaging, which can support the identification of temperature differentials associated with moisture ingress, insulation discontinuities, or abnormal heat patterns. Thermal data is used as a supplementary input and is interpreted alongside visual observations by qualified professionals.

Thermal data is used as a supplementary input and is interpreted alongside visual observations by qualified professionals.

During deployment, visual and thermal data are recorded and can be reviewed, annotated, and retained as part of inspection records. Depending on inspection scope, visual and thermal information may be captured in the same inspection exercise or through separate passes to support correlation and clearer assessment.

• 1. Clear visual evidence of inspected conditions
• 2. Traceable documentation of inspection coverage
• 3. Improved communication between engineers, owners, and regulators

NIMBLER™ enhances the quality and consistency of inspection documentation, but it does not replace professional judgment or statutory responsibilities. Interpretation of inspection data, reporting, and regulatory submissions remain the responsibility of the appointed professionals and building owners.

No. NIMBLER™ uses AI to assist with visual analysis by highlighting potential anomalies during inspection.

AI does not make inspection decisions or replace professional judgment. It functions as a decision-support tool to help inspection teams focus attention on areas that may warrant closer review.

AI models used by NIMBLER™ are constantly updated to reflect new camera and defect types.

• 1. Cracks, spalling, and surface deterioration
• 2. Corrosion and material degradation
• 3. Moisture ingress and efflorescence
• 4. Insulation defects and discontinuities
• 5. Debris accumulation and foreign objects
• 6. Installation issues in services and fixtures

Updates are managed to ensure consistency with inspection objectives and do not override professional assessment processes.

• 1. Above-ceiling and service voids
• 2. Roof and Secondary Roof Areas
• 3. Beneath Raised Flooring
• 4. Drain and Utility Systems

• 1. Airports
• 2. Retail Malls
• 3. Large Office Buildings and Flatted Factories
• 4. Public Housing and Condominium Blocks
• 5. Public Drains and Canals

Suitability for specific environments depends on site conditions, inspection objectives, and deployment constraints.

No. The use of NIMBLER™ does not alter statutory responsibilities, professional accountability, or regulatory obligations.

It can support better-informed decision-making by improving access, consistency, and documentation, helping stakeholders demonstrate due diligence when used within established inspection processes.

NIMBLER™ is designed to be deployed with minimal disruption to occupied buildings, including inspections conducted while spaces remain in active use.

In several deployments, compact NIMBLER™ variants have been introduced into above-ceiling spaces through existing light-fixture openings, avoiding additional access cuts or removal of ceiling panels. Inspections have been conducted while occupants were present beneath the false ceiling, with inspection activity contained above the ceiling line.

This reduces the need for cordoning, after-hours work, or tenant displacement.

Operation is typically carried out by trained operators. Inspection planning, interpretation, and reporting remain the responsibility of qualified engineers or appointed professionals.

Yes. Repeated inspections using NIMBLER™ can support condition tracking and trend observation over time.

When used alongside established asset management frameworks, inspection data can inform maintenance planning, risk prioritisation, and lifecycle decision-making.

Different tools serve different inspection needs.

Drones are effective in open or visually unobstructed spaces, while crawlers like NIMBLER™ are designed for enclosed, cluttered environments where proximity and stability are critical. Many organisations use a combination of methods depending on the inspection context.

NIMBLER™ is designed to be applicable across the majority of building types where concealed or constrained spaces exist.

Above ceilings, within service voids, crawl spaces, secondary roofs, drainage systems, and other concealed areas are common across residential, commercial, institutional, and industrial buildings. NIMBLER™ is engineered to operate in these environments and has been deployed in a wide range of building conditions without requiring building-specific customization.

In most cases, NIMBLER™ can be integrated directly into existing inspection workflows with minimal preparation. Rather than determining whether the platform is suitable, the discussion typically focuses on which inspection objectives and configurations (visual, zoom, thermal) best support the site’s needs. MyrLabs supports this alignment through a short technical discussion.
