Mine & Tunnel Inspection Robot Dog

Why underground operations buy this

Underground, every inspection is a person in a hazard zone

No GPS, no easy automation

Satellite navigation ends at the portal. Fixed infrastructure (rails, cameras) only covers selected points. Legged robots with LiDAR SLAM walk the actual route — ramps, rubble, water, and all.

Gas and ventilation risk

Methane, CO and oxygen-deficient zones make routine walkdowns a permit-controlled activity. A robot with onboard gas sensing takes the readings before anyone walks in.

Long distances, short shifts

Kilometres of drift and conveyor routes cannot be walked daily. Areas between scheduled inspections stay blind — conveyor hot spots (the same failure mode that drives switchyard thermal scanning), water buildup and roof changes (similar to what post-incident structural inspection looks for) go unnoticed.

What the system does underground

GPS-denied SLAM navigation — 3D LiDAR mapping and localisation in total GPS darkness; the robot follows the mapped route through drifts, cross-cuts and ramps.
Multi-gas monitoring — CH₄, CO, O₂ and site-specific sensors measured continuously along the route, with threshold alarms and gas-heat-map overlays.
Thermal inspection of plant — conveyor drives, gearboxes, motors, pumps and electrical rooms scanned for hot spots on every pass.
Visual condition capture — 4K imagery of roof conditions, rib/wall stability, water seepage and cable trays, time-stamped and geolocated on the mine map.
Obstacle handling — the robot walks over spillage, sleepers and uneven floor; on a blocked route it reports and re-routes automatically.
Dispatch from surface — mission control over the mine’s Wi-Fi / mesh network; reports surface-side within minutes of the round finishing.

Underground patrol configuration

Underground mine drift patrol — gas, thermal and visual data captured along the route

Typical configuration

Reference specification — adapted to your mine

Navigation	3D LiDAR SLAM, fully GPS-denied; re-localisation at known waypoints; autonomous re-route on blocked passage
Gas sensing	CH₄, CO, O₂ as standard; H₂S and site-specific cells configurable; continuous logging with alarm thresholds
Thermal camera	Radiometric module for conveyor drives, pump stations and electrical infrastructure
Visible camera	4K with zoom; low-light performance for tunnel lighting conditions
Environmental	Dust and humidity protected build; IP67 typical; suitability for wet drift floors assessed per site
Runtime / charging	Platform-dependent; dock or manual swap strategies matched to your shift pattern
Comms	Wi-Fi / mesh backhaul per mine standard; offline autonomy for out-of-coverage segments
Software	ROS 2 + Python SDK; dashboard with route map, gas heat-maps, thermal library and report export

Scope note: Underground deployments are assessed jointly with your mine’s ventilation, electrical and safety authorities. Robots complement — and never override — your statutory inspection regime and gas management plan.

Deployment blueprint

How a mining & tunnels deployment typically looks

A reference shape for a quadruped inspection rollout in mining & tunnels. Every system is re-scoped to your site — this is the typical starting point, not a fixed offer.

Typical environments

Underground drives, declines & junctions
Conveyor galleries & belt systems
Development faces & headings
Ventilation & pump stations

Key constraints

GNSS-denied throughout
Dust & poor visibility
Low overhead & narrow passages
Methane & airflow monitoring
Slip, gradient & wet floors

Platform, payload & routine

Rugged (optionally ex-rated, e.g. Micbot MOVENEW) quadruped
Payload: gas (CH₄/CO/O₂) + thermal + LiDAR mapping + visible
Routine: pre-shift roadway inspection, conveyor & belt monitoring, gas & strata survey
GPS-denied SLAM navigation along the route

What you can expect: Fewer personnel in hazardous and gaseous areas; earlier gas and thermal anomalies; consistent pre-shift surveys without fatigue.

From portal mapping to live rounds

Deployment and expected value

Route survey

Priority routes, hazard zones, comms coverage and gas rules mapped with your engineering team.

System build & test

Gas array, thermal thresholds and navigation behaviour tuned for your drift conditions.

Commission & handover

Supervised rounds first, then autonomy; operators and maintenance staff trained.

Questions engineers ask before a pilot

Is it certified for underground coal or gassy mines?

Certification depends on your jurisdiction and the specific classification of the workings, so we do not claim a blanket approval. We supply intrinsically safe or explosion-protected platform variants — including the Micbot MOVENEW P1/P2 — together with the technical documentation your regulator or certifying body requires, and we work to MSHA, ATEX or IECEx schemes as your site demands.

How does it navigate with no GPS underground?

By LiDAR-based SLAM: the robot builds a map of the drift as it travels and localises against it, with wheel or leg odometry and an IMU for dead reckoning where the geometry is repetitive. It does not need tags, beacons or pre-installed infrastructure. Dust and low light degrade cameras, not LiDAR, which is why it is the primary sensor underground.

Can it cope with wet, muddy and uneven ground?

Yes — rough and wet surfaces, loose rock, debris and gradients are routine for an industrial quadruped, and the enclosure is rated against water jets and dust ingress. Water deeper than the rated wading depth, and thick slurry that packs joints, will end a round. We validate the actual routes during the site survey so limitations surface before contract, not after.

What inspections does it realistically automate?

Underground the highest-value repeats are ground support and convergence checks, ventilation readings, water and sump levels, conveyor and idler condition, and gas monitoring in workings that are unsafe to enter after a blast. The robot removes the person from the exposure; it does not remove the competent person's judgement from the record.
