OUR ENGINEERING CAPABILITIES

Three disciplines.
Stronger together.

Work with us on a focused engineering challenge or connect the full development chain: model the system, develop its intelligence and integrate the software that runs it.

01 / MODEL THE PHYSICAL SYSTEM

Physical AI

Use simulation as a virtual sensor source for attached hardware. Evaluate the target’s AI and embedded software against repeatable physical scenarios.

  • Vehicle dynamics and digital environments

02 / DEVELOP THE INTELLIGENCE

AI Development

Turn sensor data into models, then evaluate their quality and prepare them for the constraints of the intended target.

  • Dataset preparation and model training
  • Evaluation, pruning and quantization
  • Inference integration and model parity checks

The physical task defines the requirements. AI and control algorithms implement the behaviour. Safety Embedded connects execution, supervision and verification on the target.

01 / PHYSICAL AI — THE SIMULATION TOOLKIT

Build each part.

VHIL / THE CONNECTED SYSTEM

Four target domains.
One simulated world.

Virtual sensor data feeds Radar, LiDAR and Camera target boards. The vehicle model provides state feedback to the Powertrain target board. Processing results and control outputs return through the configured interfaces for evaluation and vehicle response.

  • Radar, LiDAR and Camera processing on real boards
  • Powertrain target connected to the vehicle model
  • Explicit data, timing and feedback interfaces

VHIL / FROM SIMULATION TO REAL HARDWARE

Intelligence acts.
Physics answers.

Radar, LiDAR and Camera boards receive virtual sensor data. The Powertrain board exchanges state feedback and control outputs with the simulated vehicle. Each hardware path connects execution to its physical context.

01

Simulate the world

Road geometry, traffic participants, lighting and environmental conditions.

02

Supply simulation inputs

Send camera images, LiDAR points and radar data to sensor targets, and vehicle-state feedback to the Powertrain target.

03

Execute on real hardware

Run sensor processing, AI inference and control on Radar, LiDAR, Camera and Powertrain target boards.

04

Return & evaluate

Compare target outputs with the scenario. Where connected, apply control commands to the vehicle model.

Hardware results → evaluation Connected control → vehicle response → next observation

From a component question to a system question.
How does a sensor configuration affect the perception input? How does a delayed decision change the vehicle’s response?

02 / AI DEVELOPMENT

From sensor data
to deployable models.

Develop the model and its execution path together. Our radar CNN workflow connects data preparation, training, optimization and native inference integration.

Prepare & train

Organize sensor datasets, inspect labels and scenario coverage, and separate training, validation and test data.

02

Export model artifacts, connect native inference and compare outputs with the reference implementation. Measure timing and resources on the intended target.

03 / SAFETY EMBEDDED

Defined behaviour.
Supervised execution.

Build safety-oriented embedded functions with explicit operating limits, input validation, command supervision and defined fault responses. Connect requirements to implementation and verification on the intended target.

Explore Mobile Robot Architecture
01

Firmware & controlled execution

C/C++ components, startup integration and RTOS task organization, with explicit timing, memory and interface constraints.

02

Supervision & fault handling

Validate sensor inputs and command limits, manage operating-mode transitions, and define responses to stale data, communication loss and detected faults.

03

Requirements & verification

Connect requirements, software components and test scenarios. Check boundary conditions, fault responses, execution timing and diagnostics on the intended target.

Engagements can focus on one discipline or combine all three. Deliverables, target platforms and acceptance criteria are defined for each project.

MODULAR BY DESIGN

One framework.
Your development path.

The SGPN SDK — Safety Guardian Perception & Navigation — provides the C/C++ foundation behind this direction. Reusable components connect sensor processing, autonomy interfaces and the physical vehicle model.

Unreal supplies the scene. Simulink supplies the vehicle equations. VHIL adapters connect virtual sensors to Radar, LiDAR and Camera boards, and the vehicle model to the Powertrain board. Results and control outputs return to the development environment.
