With its NX NextMotion platform, Arnold NextG delivers a high-availability, safety-certified control architecture that anticipates risks and responds to failures in a controlled manner – without the need for manual intervention. At the core are three key principles:
Redundancy: Safety through System Duplication
Redundancy is the foundation of autonomous operational safety. For NX NextMotion, this means every safety-critical function – from actuators and controllers to power supply – is available in multiple, fully active instances. Examples include:
- Two independent steering actuators
- Dual communication channels (CAN-FD and CAN-XL)
- Redundant power supply with failover resilience
“Redundancy isn’t necessary for the vehicle to drive. But it’s essential to keep it safe when things go wrong.” – Volvo Autonomous Solutions, 2025
Degradability: Errors are not system failures
NX NextMotion incorporates a multi-level degradation strategy based on ISO 26262 (ASIL D), SIL3 and ISO 21434 certified safety logic. In the event of a failure, the system does not shut down immediately – instead, functions are selectively scaled back while maintaining a safe operational state.
This logic is not reactive but proactively modelled – calibrated to the threat level of the specific deployment context. The result: functional continuity at the highest safety level.
Safety Architecture: Scenario-Based, Not Component-Based
Arnold NextG takes a systems-level view of safety. The focus isn’t just on the integrity of individual components, but on the functional consequences: What must never happen in case of failure – and how can it be prevented?
Key technical implementations include:
- Segregated control logic for steering, propulsion and braking
- Decentralised controllers with autonomous decision-making
- Black-channel architecture to ensure data integrity, even under interference
- Permanent system self-check every millisecond during operation
In Practice: Autonomy That Stays Operational, Even Under Failure
Whether as part of an unmanned defence convoy, during evacuations in crisis zones or delivering critical infrastructure support during disasters: NX NextMotion remains operational – even with partial system failure. That’s the difference between robust technology and true safety architecture.
Conclusion: Safety Isn’t a Promise – It’s Engineered
Future-ready mobility demands systems that continue to function when others fail. Redundancy, degradation strategies and certified safety architecture are not just features of Arnold NextG – they are at the heart of the company’s engineering philosophy. Developed and manufactured entirely in Germany, NX NextMotion delivers system reliability in real-world conditions.
Because those who carry responsibility need systems they can rely on.
