Market size
The inspection and maintenance robotics market was worth USD 2.89 billion in 2024 and is forecast to grow at 15.8 % CAGR to 2030 (cite as: 8scale Scalebook 2025).
This inspection & maintenance robotics market report is published by 8scale, with Viktor Klein as the named analyst. Scope is global demand, with reporting depth on worldwide.
Separate the two numbers before you use them. USD 2.89 billion is our base-year value for 2024, built bottom-up across the eight segments we track. The 15.8 % CAGR to 2030 is an estimate, not a verified fact, and the residual uncertainty grows in the outer years.
Two variables move that forecast more than any technology milestone: how quickly Robotics-as-a-Service contracts displace CapEx purchases, and how many pilots convert into multi-site framework agreements. Neither is settled, so treat 2030 as a range rather than a point.
We state base year, forecast year and method with every figure. A forecast that reaches you without those three is not comparable to this one, whoever published it. The calculation logic sits in our industrial market sizing methodology, and the freely citable headline numbers are collected on the inspection robotics market statistics page.

Segments tracked
Version and author first: the current edition is Scalebook 2025, Inspection & Maintenance Robotics Market Report, written by Viktor Klein, Managing Director of 8scale and the named analyst behind the research.
The edition is dated by year, not by a rolling timestamp. Base year for all market values is 2024. Forecast horizon is 2030. Any revised numbers appear in a new edition with its own year, so a quoted figure always stays traceable to one version.
Method runs in three steps. 01 AI-first data harvest: we scrape patents, LinkedIn, webinars, YouTube demos and premium databases, feeding large-language models tuned on robotics vocabularies. 02 Programmatic precision distillation: only the strongest signals survive. 03 Expert validation: seasoned industry engineers and business leaders from our expert network review every result that survives the distillation for plausibility and blind spots.
That final step is the one that matters. A model can size a market from public noise; only operators can tell you that a turnaround window is eight days, that the tank is ATEX Zone 1, and that the PLC is decades old. Our numbers rest on deployment-level primary data, asset-level KPIs, operator interviews and real inspection and maintenance spend.
The report is built for maximum insight per minute of reading and is distributed as a gated PDF by email. Headline figures stay free to quote with the string: cite as: 8scale Scalebook 2025. Services are B2B only.
About this report
Contents
01
Market value for the 2024 base year, the CAGR to 2030 and the fastest-growing segment, each with base year, forecast year and the citation string attached.
02
The eight inspection and maintenance robotics segments, with technology definition, typical operating context and the deployment barriers that decide whether a segment scales.
03
Eight heavy-industry verticals with their annual inspection and maintenance spend, so you can size a robotics opportunity against the budget it actually competes for.
04
Asset owners, industrial service providers, technology manufacturers, investors and analysts, academia, startups and scaleups, policy makers, with the decision each group takes from the data.
05
The three-step method in full: AI-first data harvest, programmatic precision distillation, expert validation. Written so you can judge the numbers rather than trust them.
06
Neutral analysis of active suppliers in the field. The key-players list for this edition is a pending input and is documented as such, not padded with logos.
Eight segments
We track eight segments, and legged robots grow fastest at 25 % CAGR (cite as: 8scale Scalebook 2025), well above the 15.8 % market average.
The eight are: drones and UAVs; underwater ROVs and subsea systems; legged robots; stationary and teleoperated manipulators; robotic software and digital twins; climbing robots; wheeled and tracked UGVs; and pipe-crawling and pipeline robots.
Segment percentage shares by value are not published in this version. We will not estimate a share to fill a chart slot. A share you cannot audit is worth less than an honest gap.
The segmentation is cut by operating context, not by marketing category. A confined-space drone in an ATEX Zone 1 vessel and a legged robot walking a fixed route through a compressor hall are different businesses: different certification, different payload economics, different buyer inside the plant.
That is also where the growth rate needs reading carefully. Legged robots grow fastest from a small base, and much of that volume today is routine data collection on brown-field sites with decades-old PLCs. Sensor payload, data integration and permit-to-work handling decide whether those units stay after the first year.
If you build in one of these segments, the useful question is which industry budget your unit is billed against, and whether your price sits inside a CapEx line or an OpEx line. We work that question through with robotics vendors on our market intelligence for robotics companies page.

Hull, tank and subsea inspection tied to class society survey cycles and dry-dock slots. Annual spend, 2024, global (cite as: 8scale Scalebook 2025).
The full key-players list for this edition is not published in this edition, and we would rather flag the gap than fill it with logos.
What is already documented are analysed cases. Flyability, Gecko Robotics and ANYbotics appear as neutral third-party analysis of deployed systems. They are not customers of 8scale, and nothing in the report should be read as an endorsement or as a commercial relationship.
Our company profiles assess what survives procurement, not what appears in a launch video. We look at evidence of fleets in production rather than pilots, certification against the operating context, ATEX zone ratings, confined-space and OSHA-relevant procedures, the commercial model, CapEx sale versus Robotics-as-a-Service, the service and spare-parts footprint in each region, and how inspection data lands in the customer's maintenance system.
That last item ends more deployments than any technical failure. A robot that produces reports nobody can import into the CMMS becomes a second, parallel inspection process, and the plant cancels it at the next budget round.
Operators use this section as the starting point of a vendor shortlist, then narrow it against their own assets. We take that step further with asset owners on the market intelligence for asset owners page, where selection criteria are matched to specific plants and turnaround windows.
If you need a named, scored supplier landscape for one segment or one country, that is a custom study, not a report chapter. Tell us the question and we will scope it.

COMMON QUESTIONS
USD 2.89 billion in 2024, forecast to grow at 15.8 % CAGR to 2030 (cite as: 8scale Scalebook 2025). The 2024 value is our base-year figure; the CAGR is an estimate with widening uncertainty toward 2030. Always quote both the base year and the forecast year.
Legged robots, at 25 % CAGR (cite as: 8scale Scalebook 2025), the fastest of the eight segments we track. Read it in context: growth comes off a small base, and retention after year one depends on payload value, data integration and permit-to-work handling.
Use the string: cite as: 8scale Scalebook 2025, together with the base year 2024 and the forecast year 2030. Headline numbers are free to quote for journalists, analysts and academics. The full set of citable figures sits on our inspection robotics market statistics page.
Both are pending inputs for this edition, and we do not estimate percentage shares to complete a chart. Where a number is unverified, we say so. If you need segment shares or a scored supplier landscape now, that is a custom study on your specific question.
No. Any third-party number, including the widely quoted McKinsey pilot-stall figure, appears only as cited in Scalebook 2025, and never as 8scale data. Only the market value, the CAGR, the segment count and the spend figures are our own.
