FX Aegis Ultra+ Quadruped Robot Dog

Some sites are made of corridors and car parks. Others are made of gravel yards, grass verges, loading docks, stairwells and broken ground. On the second kind, wheels stop being an advantage and legs become the whole point. The FX Aegis Ultra+ is Faraday Future's answer for that terrain: the top of the legged Aegis line, built on the industrial-grade Aegis Ultra platform.

The Aegis Ultra is the industrial configuration of the Aegis series, engineered for professional deployment in security, inspection, research and AI development. On that platform:

• NVIDIA Orin NX 16G computing handles real-time decisions on the robot itself.
• It reaches 5 m/s and climbs slopes of 30 to 40 degrees.
• It clears obstacles up to 35 cm and carries up to 10 kg.
• IP54 protection suits semi-outdoor and industrial settings.

The "+" designates the higher-tier configuration of this legged platform, as the Ultra-W+ does for the wheel-legged line. Confirm exact configuration details for the "+" tier against Faraday Future's current datasheet when ordering.

Background

The Aegis family

Faraday Future, the California electric-vehicle company, entered embodied AI in 2026 with three robots, including the FX Aegis, a professional quadruped for security and companionship. The Aegis series went on to pass the full compliance certification required for formal sale in the United States. It has since grown into a family that spans:

• entry-level display and education models
• the industrial Ultra and Ultra+ on legs
• the Ultra-W and Ultra-W+ on wheels and legs
• the large Hyper for extreme environments

One brain across every form

All Faraday Future robots share one embodied-AI architecture, which the company calls "one brain, multiple forms." A skill built for one robot can be adapted to another through Faraday Future's skills ecosystem. That means the Ultra+ benefits from work done across the company's humanoids, quadrupeds and mobile manipulators.

Built for Ground That Isn't Flat

Twelve degrees of freedom, three per leg

The Ultra platform walks on four articulated legs with 12 degrees of freedom. That lets it place each foot on uneven surfaces, climb stairs and steep grades, and step over obstacles up to 35 cm high. For sites where the ground changes constantly, legged locomotion keeps the robot moving where a wheeled platform would need help.

Industrial protection

IP54 protection guards against dust and water splashes, so the Ultra platform can work in semi-outdoor and industrial environments: yards, plant floors, construction zones and covered outdoor areas.

Payload capacity

With up to 10 kg of payload, the Ultra can carry sensors, communication equipment or mission modules without giving up mobility.

Sensing, Computing and Expansion

Onboard intelligence

The NVIDIA Orin NX 16G computing module runs perception and decision-making directly on the robot, so it can track targets as it moves. That is critical for patrol and inspection work where network links can't be guaranteed.

Expansion ports for real missions

The Ultra platform's expanded hardware interfaces support:

• 3D radar for mapping and perception
• depth cameras for close-range 3D sensing
• RTK positioning for centimeter-level outdoor location
• 4G connectivity for remote patrol beyond Wi-Fi coverage

Across the Aegis family, Faraday Future also lists options such as LiDAR, robotic arms, fire extinguishers and dedicated security modules.

Development for every skill level

The Ultra platform offers full secondary development through:

• an SDK and APIs
• NVIDIA Isaac Sim simulation
• an advanced visual programming platform with Python support
• the OpenClaw no-code tool, for users newer to robotics

Over-the-air updates keep the platform current. Faraday Future has said future updates will unlock autonomous navigation, environmental scanning and patrol, and self-charging with a separately sold dock.

Specifications

These are the published specifications of the Aegis Ultra platform. The Ultra+ is its higher-tier configuration, so confirm Ultra+ additions, such as computing, sensors and included packages, against Faraday Future's current datasheet.

Ultra+, Ultra or Ultra-W?

Applications

• Industrial inspection. Rounds through plants, yards and utility sites, with depth and radar sensing for anomalies.
• Security patrol on rough ground. Perimeters with grass, gravel, slopes and stairs that wheeled robots can't patrol alone.
• Construction and infrastructure sites. Progress monitoring and site walks over unfinished, changing terrain.
• Outdoor surveying. RTK-positioned data collection for mapping and repeatable routes.
• Remote operations. 4G-connected patrol beyond the reach of site Wi-Fi.
• Research and AI development. Locomotion, perception and simulation-to-real work on an open, industrial-grade quadruped.
• Education at advanced levels. University robotics programs that need a durable, fully programmable platform.

What to Plan For

• Plan for runtime. At 1 to 2 hours per charge on the Ultra platform, long patrols need spare batteries or a charging dock. Confirm runtime for the Ultra+.
• Match protection to conditions. IP54 covers dust and splashes. It is designed for semi-outdoor work, not heavy rain or submersion.
• Confirm the "+" configuration. Request the Ultra+ datasheet to see exactly what it adds over the standard Ultra.
• Treat recordings responsibly. Patrol and inspection robots capture video and data. Set notice, retention and access policies in line with local privacy law.
• Check radio approvals. 4G, 5G and other radio modules may need local certification outside the United States.
• Pilot first. Prove one inspection route or patrol, then add payloads and robots as the program grows.
