Mission footage · autonomous lava-tube exploration, Iceland
Autonomous inspection for the places no signal reaches.
No GPS, no connectivity, no pilot. The robot runs the round; a decision-ready report reaches the morning meeting.

What happens on every run
Runs the round itself
The robot runs scheduled missions through kilometers of drifts with no GPS, no radio coverage, and nobody watching. The same mission layer explored more than 1 km of an Icelandic lava tube on its own.
Compares it to the last run
Each run is registered against the baseline your team approved. Convergence, debris, water ingress, and support damage appear as measured differences, each with a location and a magnitude.
Reports what needs attention
When the robot reaches comms, the data syncs and a report goes to the inboxes you choose: what it saw, what changed, what needs attention. Your engineer opens a document with the evidence attached.
A report the shift can act on
A dated PDF in the inbox before the morning meeting. Each finding is ranked by severity and linked to the image, the position, and the time it was captured.
Everything stays on your site
The AI that reads imagery runs on the robot and a server you host. No cloud calls, no training on your data. Air-gapped sites work.
A site history you own
Every mission adds a dated, evidence-backed entry to the site's history, stored in open formats on your premises. If we part ways, you keep all of it.
No new software for the crew
Day one is a PDF in the inboxes you choose. We build deeper integrations when your team asks for them.
Inspection report
Sarthi Robotics
Delivered 06:12,
before the morning meeting
Two findings need attention.
Everything else checked out.
Findings, evidence imagery, positions, and readings are the customer's. Nothing from a real site is published here.
Every run compared to the last
A survey scanner records a place once. Sarthi repeats the same route on a schedule, so each report shows what moved, what grew, and what is trending toward failure, measured against the baseline your team approved.
The pair below is an illustration. Real pairs come from your own runs and stay on your premises.
Made for the part of the site with no signal
Most inspection robots need a network, a map, or a pilot. A drift a few hundred meters past the portal has none of the three.
- Fleet platforms assume a live network to the robot.
- Sarthi's missions run entirely on the robot. The link is optional; the round happens either way.
- Survey scanners capture a site once, when someone carries them there.
- Sarthi is resident. The same route on schedule, every run compared to the last.
- Inspection robots want a pilot, a dock, or a pre-mapped facility.
- Sarthi enters unmapped workings and comes back with the map.
Built by the researcher who flew the world-first mission
Sarthi grew out of a PhD and a postdoc at Luleå University of Technology: eight years of field work on robots that need nothing from the site, 20 peer-reviewed publications, and missions in an Icelandic lava tube and an operating iron-ore mine.

Where the missions ran
Underground trials with Nordic and European operators across three EU research programs, and one world-first that has not been repeated.
World-first lava-tube exploration
Iceland
A drone explored and mapped more than 1 km of a naturally formed lava tube, fully autonomously: no GPS, no link, no pilot. The first mission of its kind anywhere.
