Fail-Safe vs. Fail-Operational: A New Approach
Zoox applies aviation-inspired safety standards to its robotaxi, incorporating fail-operational systems that allow continued safe operation during faults, unlike traditional fail-safe systems that may shut down or limit functionality. This methodical approach, inspired by aviation, industrial, and automotive best practices, ensures the vehicle remains operational, prioritizing rider safety under all circumstances.
Redundant Steering and Braking Systems
The Zoox robotaxi features primary and backup steering systems, enabling safe navigation and stopping in case of a failure. Its multi-technology braking system provides additional reliability, ensuring the vehicle can stop safely even if a component malfunctions. This multi-layered design deviates from conventional vehicles, making Zoox uniquely resilient.
Robust Power Supply Redundancy
To eliminate single points of failure, Zoox integrates two batteries into its powertrain. If a battery or power converter fails, the redundant system ensures the vehicle can safely pull over, activate hazard lights, and open doors, maintaining operational safety and rider security.
Advanced Self-Diagnostics for Proactive Maintenance
Zoox’s real-time diagnostic system continuously monitors hardware, software, and firmware, offering detailed insights into component health. Unlike traditional vehicles’ basic alerts, this advanced system detects potential issues early, enabling proactive maintenance to prevent unexpected failures during operation.
Sensor Suite for Seamless Navigation
Built from the ground up, Zoox’s robotaxi features a 360-degree sensor suite with overlapping fields of view, ensuring no blind spots. Even Jika sensor fails or is occluded, the vehicle maintains full situational awareness, enabling safe and autonomous navigation at all times.
Connectivity Through Redundant Modems
Zoox employs three cellular modems to balance and replicate data streams, ensuring continuous connectivity for remote monitoring and teleoperations. This redundancy guarantees operational reliability, even in areas with variable cellular network performance, as long as one modem remains functional.
Redundant Driving Algorithms for Safety
Zoox’s driving stack includes a dedicated collision avoidance system, providing redundancy in perception, prediction, and decision-making. This system reacts faster than human drivers, making split-second decisions to brake or swerve, enhancing safety for passengers and other road users.
A Commitment to Rider Safety
Zoox’s robotaxi integrates over 100 safety innovations, with redundancy at its core. From steering and braking to power, sensors, and connectivity, every critical system is designed to ensure no single failure compromises safety. This commitment to resilience and continuous improvement redefines autonomous mobility, making every ride safe and reliable.
