Autonomous systems for India's defence.
drubelabs designs and builds unmanned ground vehicles, uncrewed aircraft and the operating system that runs them. Hardware, autonomy and software, made under one roof in Kerala.
Machines that go first.
The most dangerous ground on any mission should be crossed by a machine, not a soldier.
We build rugged robots and aircraft that patrol, carry, sense and strike in places people shouldn't have to go. Every system is designed, fabricated and tested by our own engineers, from the gearbox and circuit boards to the software an operator uses in the field.
Building it ourselves means we can change a design in days, support it for years, and keep critical technology in Indian hands.
Ground, air and the software between them.
STRYKER
Unmanned ground vehicle for patrol, reconnaissance and logistics.
Explore STRYKER AirNemesis
Uncrewed aerial systems, including loitering munition variants.
Explore Nemesis SoftwareDRL Sentinel OS
The defence operating system that runs our robots, drones and UGVs, alone or as a fleet.
Explore Sentinel OSSTRYKER
An unmanned ground vehicle for patrol, reconnaissance and logistics. It sees at night, carries heavy loads and keeps going for hours.
Sees in the dark
Thermal, NoIR and night vision cameras on a pan-tilt head, backed by LiDAR and mmWave radar for obstacle detection when visibility drops.
Goes where wheels struggle
Four-wheel drive with Ackermann steering for the road and skid turning for tight spaces. High ground clearance for rough terrain.
Senses the environment
Onboard flammable gas detection, temperature, humidity, barometric altitude, tilt and IMU, reported live to the operator.
Built to be reconfigured
A modular deck and electronics let units swap payloads for patrol, resupply or surveillance without redesigning the vehicle.
NEMESIS
Uncrewed aerial systems for surveillance and precision strike, including loitering munition variants.
Precision strike
Loitering munition variants can hold over an area, observe, and engage only when the operator confirms the target.
Operator in command
Every engagement decision stays with a trained human operator, with the ability to abort up to the final moment.
Runs on Sentinel OS
The same operating system as our ground vehicles, so one team can plan, fly and monitor air and ground missions together.
Designed and built in India
Airframe, electronics and flight software are developed in-house at our Kerala facility.
Nemesis is available only to authorised government and defence customers, in line with Indian export and end-use regulations. Specifications and demonstrations are shared on request.
DRL
Sentinel OS
The operating system for autonomous defence systems. A proprietary Sentinel layer on a proven Linux foundation, built to run robots, drones and UGVs alone or as a coordinated fleet.
One layer that ties it all together.
Sentinel Core sits between the hardware and the mission software. It starts and supervises services, handles communication between systems and keeps each unit manageable in the field.
Because it runs on standard Linux hardware, the same software stack moves from a Raspberry Pi on a small drone to an edge computer on a UGV to a server in a command post.
Built for defence
Designed from the start for autonomous defence and robotic systems, not adapted from consumer software.
Edge AI ready
Run perception, AI models and sensor processing on the vehicle itself, where decisions need to happen.
ROS 2 ready
Works with the robotics standard used across drones, UGVs and research platforms.
Distributed autonomy
Multiple systems share information and operate cooperatively as one team.
Secure and resilient
Isolated services, secure communication and automatic recovery keep units running when something fails.
Hardware agnostic
Raspberry Pi, x86 PCs, edge computers and servers. Choose hardware for the mission, not the software.
No cloud required.
Core autonomous functions keep working without an internet connection. When networks are jammed, denied or simply absent, Sentinel OS systems carry on with the mission.
From one robot to a full command network.
- A single robot One UGV or drone, fully autonomous on its own hardware.
- A cooperative fleet Several units share data and coordinate tasks with each other.
- Command infrastructure Fleets connect to servers and command posts for oversight at scale.
Built for the missions that wear people down.
Perimeter patrol
Repeat routes around bases and borders day and night, flagging movement and heat signatures.
Reconnaissance
Send cameras and sensors ahead of a team, on the ground or from the air.
Logistics
Carry up to 400 kg or tow trailers of supplies across rough terrain.
Precision engagement
Operator-controlled strike against confirmed targets with Nemesis.
Proven on the hardest terrain we could find.
Our autonomy was first built for Scout Bot, a rover that cleans beaches on its own. Salt, sand, heat and shifting ground taught us how to build machines that keep working when conditions are against them.
Scout Bot remains our civil platform. The same engineering now goes into systems for defence and security.
Made in Kerala.
A small team of engineers who design, machine, solder and code every system we ship.
Based at Kerala Startup Mission, Kalamassery. Previously incubated at AIC Anna Incubation Centre, Anna University, Chennai. Supported by the Onshape Startup Program.
