The Inspection Problem Nobody Talks About: Confined Spaces, and the Terra Xross 1
Ask most people to picture a drone inspection and they see an aircraft circling a wind turbine or tracing a power line against open sky. That is the easy version of the problem, and to a large extent the industry has solved it. GPS is available, obstacles are sparse, and if something goes wrong the aircraft has room to recover.
Now picture the other inspection: a technician climbing into a pressure vessel, a boiler, a storage tank, a sewer, or a mine shaft. No GPS. No natural light. No room for error. And — this is the part that should stop you — a human being physically inside a confined space that is genuinely dangerous. Confined space entry is among the most hazardous routine tasks in industrial work, and it carries costs that go far beyond the risk itself: permits, atmospheric testing, standby rescue teams, scaffolding, and shutting down the asset entirely while the inspection happens.
That is the problem indoor inspection drones exist to solve, and it is why we partnered with Terra Drone to expand access to the Terra Xross 1 indoor inspection drone across the U.S. for industrial, infrastructure, and public safety operations. The value proposition is refreshingly blunt: send the drone in so a person does not have to.
Indoor inspection is a fundamentally different engineering discipline, and this is where a lot of buyers get caught out. Without GPS, the aircraft must navigate using onboard sensing. In a dark, enclosed, often dusty or steamy environment, it must generate its own light and produce imagery clear enough to support an engineering judgment about asset condition. It must survive contact and operate in tight geometry where a conventional airframe would simply not fit. And it must be reliable enough that recovering a downed drone from inside a boiler does not become its own confined-space entry — which would defeat the entire purpose in the most ironic way possible.
These constraints are why you cannot simply take an outdoor enterprise platform, strap a light to it, and call it an indoor solution. It is a distinct class of aircraft. We keep the full range together in our indoor inspection drone collection so teams can compare purpose-built options rather than trying to force an outdoor airframe into a job it was never designed for.
The economics tend to convince people faster than the safety argument does, which says something uncomfortable about how industries actually make decisions. A single confined-space inspection can require scaffolding, permits, atmospheric monitoring, a standby rescue team, and a full asset shutdown. Multiply that across a facility’s annual inspection schedule and the numbers get large quickly. An indoor drone compresses that into a fraction of the time, with a fraction of the human exposure, and produces a repeatable visual record you can compare against last year’s inspection — which is itself a capability most manual inspections never deliver.
That last point is underrated. Manual inspection produces a report. Drone inspection produces data — imagery you can revisit, compare over time, and use to build an actual condition history for the asset rather than relying on the recollection of whoever went in last. Over an asset’s lifecycle, that history is worth more than any single inspection.
Because these deployments are operationally demanding, support matters as much as the airframe, and teams that skip this generally regret it. The Terra Xross 1 with Care Coverage exists for exactly that reason — these aircraft work in genuinely punishing environments, and a support plan is not an upsell here, it is a realistic assessment of what operating inside a tank does to hardware.
Indoor inspection sits alongside the broader shift toward drone-based asset management we see across energy infrastructure inspection. The principle is the same in both: get the sensor where the risk is, and keep the human out of it.
If your team is still sending people into confined spaces because “that’s how we’ve always done it,” the technology has moved past that. It is worth a serious look.
