Confined Space
Inspection Robots
Send a robot into the tank, vessel, or silo — not your people. Actel Robotics deploys autonomous inspection robots into permit-required confined spaces to capture the visual, thermal, and gas data you need, with zero human entrants exposed to the hazard.
Confined Space Entry Is the Most Dangerous Job on the Site
Storage tanks, pressure vessels, silos, sewers, and vaults are classified as permit-required confined spaces under OSHA 1910.146 for a reason — atmospheric hazards, engulfment, and entrapment make human entry high-risk and slow. Every entry demands atmospheric testing, permits, standby rescue, and downtime.
Robotic confined space inspection changes the equation: the robot goes in, your people stay out. An agile mobile platform like Boston Dynamics Spot navigates the interior, collects a complete data set, and comes back out — turning a hazardous, permit-heavy entry into a repeatable, documented inspection mission.
Robotic entry keeps personnel out of the hazard zone entirely
A Full Data Set From a Single Entry
One redeployable robot captures every modality you would otherwise need multiple entries — and multiple entrants — to collect.
Visual & Corrosion
High-resolution PTZ imaging with zoom to document wall condition, corrosion, weld integrity, and product buildup on interior surfaces.
Thermal / IR
Detect heat anomalies, refractory damage, insulation gaps, and hot spots that signal failures before they force an unplanned shutdown.
Gas & Atmosphere
Onboard gas detection reads the interior atmosphere continuously — mapping hazards without a human relying on a personal monitor inside.
3D Laser Scan
Build a digital twin of the interior, measure remaining wall thickness zones, and compare condition mission-over-mission to track degradation.
Acoustic Leak Detection
Identify pressurized leaks, cracks, and airflow anomalies through ultrasonic and acoustic monitoring that human ears cannot hear.
Documented & Repeatable
Every mission follows the same route and delivers a time-stamped record to your asset management system — inspection evidence without the entry paperwork.
Zero Entrants. Full Coverage. Less Downtime.
Replacing manual confined space entry with a robot removes the hazard, shrinks the permit and rescue-team overhead, and lets you inspect more often because each mission is faster and safer to run.
Robotic Confined Space Inspection FAQ
Can a robot inspect a confined space instead of a person?
Yes. A mobile inspection robot like Boston Dynamics Spot enters tanks, vessels, silos, and other permit-required confined spaces to capture visual, thermal, and gas data — so no human entrant is exposed to the hazard.
What kinds of confined spaces can robots enter?
Storage tanks, pressure vessels, boilers, silos and hoppers, sewers and wet wells, pipelines, digesters, and industrial vaults. We assess each space for opening size, atmosphere, and terrain before selecting the platform and payload.
How does this help with OSHA compliance?
OSHA 1910.146 regulates permit-required confined spaces because of atmospheric, engulfment, and entrapment hazards. Robotic entry removes the entrant from the hazard, cuts the permit and rescue overhead tied to human entry, and produces a documented, repeatable inspection record.
Do you serve the Houston and Gulf Coast market?
Yes — Actel Robotics is based in Sugar Land, TX and deploys confined space inspection robots across Texas, Louisiana, and Oklahoma, including petrochemical, refining, power, and water/wastewater facilities.
