Operating system for autonomous defence systems
DRLSentinel OS
A proprietary Sentinel layer on a proven Linux foundation. It runs robots, drones and UGVs on their own or as one coordinated fleet, from a single Raspberry Pi to a full command network.
Illustrative: units sharing data
Four layers. One system.
Tap a layer to see what it does. Sentinel Core is the part we built: the layer that turns standard Linux hardware into a defence system.
Robotics and AI
The mission software: what each robot or drone actually does.
- ROS 2 applicationsNavigation, control and mission logic built on the robotics standard.
- PerceptionCamera, LiDAR and radar processing on the vehicle.
- Local AI modelsDetection and classification that run at the edge, without a connection.
Sentinel Core
The central system layer for services, communication and management.
- ServicesStarts, isolates and supervises every service on the unit.
- CommunicationSecure links between units and command, with or without a network backbone.
- ManagementKeeps every unit in a fleet visible, configurable and updatable.
Linux foundation
Sentinel OS is built on a proven Linux base rather than a new kernel written from scratch.
- ProvenDecades of real-world use across servers, vehicles and embedded devices.
- Supported hardwareRuns on the boards and computers already in the field.
- Open ecosystemStandard tools, drivers and the ROS 2 ecosystem work as expected.
Your hardware
Hardware agnostic: choose computers for the mission, not for the software.
- Raspberry PiSmall drones, sensors and lightweight nodes.
- x86 PCs and edge computersGround vehicles and AI-heavy workloads.
- ServersCommand posts and fleet infrastructure.
Sentinel Core keeps every unit running.
It sits between the hardware and the mission software, so robotics teams can focus on what the vehicle does, not on keeping it alive.
Supervised and isolated
Each service runs on its own. If one fails, Sentinel Core contains it and brings it back without taking the unit down.
Unit to unit, unit to command
Robots, drones and command posts talk to each other securely, directly or through command infrastructure.
One fleet, one view
See the state of every unit, change its configuration and roll out updates from one place.
Cut the cloud. The mission continues.
Core autonomous functions run on the units themselves. Try it: cut the cloud link or knock a unit out and watch the rest keep working together.
- A single robotOne UGV or drone, fully autonomous on its own hardware.
- A cooperative fleetSeveral units share data and coordinate tasks with each other.
- Command infrastructureFleets connect to servers and command posts for oversight at scale.
Built for robots that think on board.
Decisions happen where the sensors are. Sentinel OS is ready for both the robotics standard and the AI workloads that run on modern vehicles.
Perception on the vehicle
Run AI models, perception and sensor processing locally, so a unit can still see and decide when its link is weak or gone.
- Local AI inference
- Camera, LiDAR and radar processing
- Sensor fusion on the unit
The robotics standard
Designed for robotics, drones and UGVs. Teams build with ROS 2 and the tools they already know.
- ROS 2 nodes and packages
- Drones, UGVs and fixed sensors
- Same stack from lab to field
Secure and resilient at every layer.
Defence systems get attacked, jammed and damaged. Sentinel OS is designed to contain problems, protect its links and recover on its own.
Isolated services
Services are kept apart, so a fault or compromise in one does not spread to the rest of the unit.
Secure communication
Links between units and command are protected end to end.
Recovery
Units detect failures and restore themselves, so they keep working in the field without a technician.
Runs on what you already have.
The same software stack moves from a small drone to a ground vehicle to a server in a command post.
| Hardware | Typical role | Example |
|---|---|---|
| Raspberry Pi | Lightweight nodes and small aircraft | Sensor posts, small drones |
| x86 PC | Vehicles and ground control | Operator stations |
| Edge computer | AI and perception on board | UGVs such as STRYKER |
| Server | Fleet and command infrastructure | Command posts |
Where Sentinel OS is today.
Sentinel OS is in active development at drubelabs and powers our own systems first.
- Core platformSentinel Core on the Linux foundation.
- drubelabs systemsRunning across STRYKER and Nemesis.
- Fleet pilotsMulti-unit trials with partners.
- Partner releaseAvailable to integrators and defence partners.
Run your systems on Sentinel OS.
We work with defence agencies and hardware partners who want one secure operating system across their robots, drones and command posts.
