Confined Space
Inspection.
Cage-protected micro-drones equipped with gas, thermal, and high-resolution visual sensors for safe inspection of tanks, silos, pipelines, pressure vessels, and industrial voids. Removes humans from the most dangerous spaces on a facility.

Zero human entry. Full visual record.
Confined-space entry is one of the most dangerous activities in any facility — falls, atmospheric hazards, energised systems, and rescue complexity all stack risk on the operator. Caged inspection drones remove the operator from the space entirely, while delivering inspection-grade visual, thermal, and gas data.
Our platforms operate GPS-denied via LiDAR SLAM, capturing 4K visual, radiometric thermal, and gas readings (CH₄, H₂S, CO, O₂). The collision-tolerant cage allows direct contact with walls, baffles, and internals without aborting the mission.
Output is a georeferenced inspection record — 3D model of internal geometry, annotated defect locations, and full atmospheric log — suitable for engineering review, regulatory submission, and asset-integrity workflows.
Interior inspection record
Georeferenced visual record of internal walls, baffles, and connections. Annotated defects with coordinates for follow-up.
Radiometric thermal
LiDAR SLAM trajectory → 3D internal model → visual orthorectification → defect annotation → atmospheric data overlay → inspection report packaging.
From access port to inspection record.
Pre-Flight Safety Review
Atmospheric assessment, isolation verification, rescue plan coordination, client safety briefing.
Internal Mission

Where this service is deployed.
Common questions.
What's the smallest space the drone can operate in?+
As small as 0.8 m in diameter, using cage-protected micro-drones built for tanks, silos, and pipelines.
Can the drone operate without GPS?+
Yes — navigation relies on LiDAR SLAM, so it works fully GPS-denied inside enclosed structures.
What does the drone sense during an inspection?+
4K visual, thermal, and gas sensors in a single ~10-minute flight, covering visual, thermal, and atmospheric-hazard data at once.
