SUNAC, the autonomous quadruped by UNTUAI Global

The robotgoes in first.

SUNAC is an AI-powered quadruped being built in India to take the first step on border patrols, hazardous inspections, disaster entries and heavy carries, so soldiers and responders don't have to.

Concept visualisation

22,500 km of frontier. Most of it patrolled on foot.

Four jobs put soldiers and responders in the most danger. Each one is a job a robot can start.

  • A BSF patrol walking along the border fence

    Surveillance

    5.15 lakh

    BSF, ITBP, SSB and Assam Rifles personnel patrol 15,000+ km of land border, 7,500+ km of coastline, the 740 km LoC and the 3,500 km LAC, through mountains, deserts, forests and snow.

  • A soldier in a mask checking a pressure gauge beside a steam leak

    Inspection

    180,000+

    CISF personnel guard nuclear facilities, refineries, chemical plants and ammunition depots, under direct CBRN and underground exposure.

  • Military trucks on a smoke-filled road beside a damaged building

    Disaster relief

    1,038

    Disaster operations run in 2024 by 16 NDRF battalions (18,556 personnel), on unstable, toxic and collapsed ground.

  • A column of soldiers climbing a snowy slope under heavy packs

    Payload burden

    20–45 kg

    Arms, ammunition, rations and radios, carried by each soldier on foot patrol. The weight drives fatigue and cuts patrol endurance.

SUNAC

Smart Unmanned Navigation Autonomous Carrier

  • Sees in the dark

    Thermal, IR and LiDAR sensing with AI detection for night operations.

  • Holds its footing

    Stable on stairs, rocks and rubble, where wheels and tracks stop.

  • Carries the load

    Moves payload continuously, without the fatigue that limits a patrol.

  • Works around the clock

    Built for 24×7 patrolling in adverse climatic conditions.

One platform. Four missions.

SUNAC goes into contaminated, confined and dangerous places before people do, so nobody is exposed on the first entry.

Border surveillance

Patrols the border, day and night.

  • 24×7 autonomous patrolling and monitoring
  • Keeps working through adverse climatic conditions
  • Real-time, secure border communication
Concept: SUNAC carrying a medical kit through rubbleConcept visualisation

Disaster reach

Reaches survivors before rescuers can.

  • Last-mile supply of food and medicines
  • Quick response when every minute counts
  • Search-and-rescue mobility across unsafe, hazardous ground

Hazardous inspection

Enters the risky zone first.

  • Goes into contaminated, confined or risky zones ahead of people
  • Zero personnel exposure on the first entry
  • For refineries, depots, chemical plants and nuclear sites

Payload carrier

Carries the load up the mountain.

  • Carries payload for soldiers across tough terrain
  • Works in harsh climatic conditions
  • Keeps essential supplies moving without a break

The US and China already field robot quadrupeds. India is at the starting line.

2005

United States

Fully operational

The global leader, including weaponised quadrupeds. 15+ companies at commercial stage.

2018

China

Fully operational

Rapid expansion, with about 70% of global sales. 15+ companies at commercial stage.

2023

India

Early adoption

100 MULE units procured in an emergency tranche. About 5 companies at an early stage.

Building India's quadruped capability now keeps the country from depending on imports when it matters most.

From lab to field

SUNAC has cleared TRL 1–4 and the lab prototype walks. The next milestone is a field-tested prototype that qualifies it for trials with Indian forces.
