What is EVAS (Edge & Void Awareness Solution)?

EVAS is an AI-powered terrain safety system that detects dangerous slopes, edges, and voids in real-time using LiDAR technology. It prevents dozer and excavator rollovers by alerting operators before they approach hazardous terrain.

How does EVAS prevent equipment rollovers?

EVAS continuously scans the terrain ahead of the equipment using LiDAR sensors and AI algorithms. When it detects a dangerous slope angle, edge, or void, it provides visual and audible alerts to the operator, giving them time to stop or change direction.

What types of equipment can EVAS be installed on?

EVAS is designed for heavy earthmoving equipment including dozers, excavators, graders, and other machines that operate near edges or on slopes. The system can be retrofitted to existing equipment or installed on new machines.

Does EVAS work in all weather and lighting conditions?

Yes, EVAS uses LiDAR technology which operates independently of lighting conditions. It works effectively in darkness, dust, fog, and other challenging environmental conditions common in mining operations.

Edge Detection Evolved: The EVAS Advantage.

Explore how our Edge Awareness System provides mining equipment operators with unprecedented terrain intelligence. EVAS transforms dangerous slopes and edges from invisible threats to clearly defined boundaries, preventing high-consequence tipping incidents while maintaining operational efficiency in all environmental conditions.

Terrain Hazard Detection

See beyond the visible edge before it's too late

Advanced sensors map the terrain ahead, detecting dangerous slopes and unstable surfaces that are often invisible to operators, especially in challenging visibility conditions.

Machine Agnostic Deployment

One system, multiple applications across your fleet.

EVAS adapts to any heavy equipment in your mining operations, providing consistent terrain safe work intelligence regardless of machine type or manufacturer. Installs on excavators, dozers, graders, or dump trucks with minimal requirements.

Illustration: an open-cut mine bench worked by four machine types at once, an excavator at the face, a dozer on the bench, a grader on the haul road and a haul truck carting

Operator Alert Interface

Clear information when and where it matters.

Intuitive visual displays and prioritized alerts provide operators with actionable intelligence without distraction, making complex terrain conditions instantly understandable.

Real-Time Safe Work Assessment

Continuous evaluation so you never guess about your work area.

EVAS doesn't just detect terrain—it analyzes multiple safe work factors in real-time, calculating slope angles and machine positioning with millisecond precision. Unlike periodic scanning systems, EVAS performs uninterrupted terrain analysis during all operational phases, maintaining vigilance without operator intervention.

Terrain Mapping

Terrain that updates as the fleet works.

Using vehicle-mounted LiDAR, Bigmate continuously maps the surrounding mine terrain as equipment operates. This real-time spatial data can be integrated into existing mine surveying and planning systems, providing more frequent terrain updates, improving visibility of changing site conditions and supporting safer, better-informed operational decisions.
