FX Aegis Ultra-W+ Wheel-Legged Robot Dog
A robot dog on legs can go almost anywhere, but it pays for that in speed, noise and battery on every flat meter. A wheeled robot covers ground efficiently, but stops at the first curb. The FX Aegis Ultra-W+ is built not to choose: it rolls the distance and steps the obstacles.
The Ultra-W+ is the highest-tier configuration of the Aegis Ultra-W, Faraday Future's wheel-legged professional quadruped. Faraday Future describes the Ultra-W as a lightweight wheel-legged robot of about 22 kg for security and companionship. It combines wheeled mobility with legged obstacle clearing, low-noise operation and open development. Launch coverage reports a top speed of more than 19.8 km/h and slopes of up to 40 degrees. That makes the Ultra-W line one of the fastest quadruped platforms in its class.
The "+" marks the step above the standard Ultra-W, the wheel-legged counterpart to the legged Aegis Ultra+. Configuration details for the "+" tier are confirmed against Faraday Future's current datasheet at the time of order.
Background
Faraday Future's Aegis family
Faraday Future, the California electric-vehicle company that moved into embodied AI in 2026, launched the FX Aegis as one of its first three robots. It positions the Aegis as a professional quadruped for security and companionship. In 2026 the Aegis series passed the full compliance certification needed for formal sale in the United States.
The Aegis family now runs from entry-level display and education models up to industrial-grade platforms. The Ultra-W+ sits at the top of the wheel-legged line:
| Configuration | Form | Positioning |
|---|---|---|
| Aegis Ultra | Legged | Industrial-grade quadruped for security, inspection, research and AI development |
| Aegis Ultra+ | Legged | Higher-tier legged configuration |
| Aegis Ultra-W | Wheel-legged | Lightweight professional wheel-legged robot for security and companionship |
| Aegis Ultra-W+ | Wheel-legged | Highest-tier wheel-legged configuration |
| Aegis Hyper | Wheel-legged, large | Industrial platform for extreme environments and heavy payloads |
Compare edition datasheets to confirm exact differences in compute, sensors and included packages.
One brain, many forms
Every Faraday Future robot runs on the company's shared embodied-AI architecture, which it calls "one brain, multiple forms." A single AI brain is adapted to different bodies, so a skill developed for one robot can be transferred to another. Faraday Future likens it to an app store for robots, and the Aegis Ultra-W+ draws on the same skills ecosystem as the rest of the range.
Design and Features
Wheels for distance, legs for obstacles
Each of the Ultra-W+'s four legs ends in a wheel. On flat ground such as corridors, car parks, campus paths and warehouse aisles, it drives like a wheeled robot: fast, smooth and efficient. When it meets a curb, step or obstacle, the legs lift and articulate to clear it. This hybrid mobility is the key reason to choose a W model over a purely legged Aegis.
Quiet by design
Faraday Future specifically highlights low-noise operation for the Ultra-W line. Rolling on wheels avoids the repetitive footfall of a walking quadruped. That matters for night patrols, hotels, residences, offices and anywhere a robot works around people who would rather not hear it.
Open development
The Ultra-W line is built for teams who want to go beyond out-of-the-box behaviors. It supports:
- secondary development
- simulation training
- multi-robot coordination
- professional payload expansion
In the Ultra tier of the Aegis family, Faraday Future pairs this openness with SDK and API access, NVIDIA Isaac Sim support and a visual programming platform with Python. The OpenClaw no-code tool is included for users who are new to robotics. Confirm the exact development stack included with your Ultra-W+ configuration.
Patrol and companionship intelligence
Across the Aegis family, Faraday Future lists:
- autonomous patrol
- follow-me capability
- integration with home, campus and industrial security systems for continuous patrol, status reporting and coordinated responses
- Wi-Fi and 5G communication, with expandable remote operation for outdoor sites, industrial locations and areas with weak network coverage
Some autonomy features, such as advanced navigation and self-charging on selected variants, are being delivered progressively through over-the-air updates.
Expandable payloads
The Aegis platform is designed to carry professional add-ons. Faraday Future lists expansion options including:
- LiDAR
- depth cameras
- communication modules
- robotic arms
- fire extinguishers
- dedicated security modules
This lets one robot be fitted for different missions.

Applications
- Security patrol. Long perimeter and campus routes covered quickly and quietly, with legged clearance for curbs, steps and obstacles along the way.
- Facility and property monitoring. Continuous rounds integrated with existing security systems, with status reporting and remote operation.
- Hospitality and residential settings. Low-noise patrol and companionship where guests and residents expect discretion.
- Industrial sites. Mixed paved and uneven terrain, fitted with inspection or communication payloads as needed.
- Multi-robot programs. Coordinated fleets sharing routes and tasks.
- Research and development. Hybrid locomotion, simulation-to-real training and custom skills on an open platform.
- Companionship and outdoor activity. A capable partner for travel, carrying gear and following its owner.
What to Plan For
- Know your terrain. Wheel-legged robots excel on mixed ground with long flat stretches. If routes are mostly rough terrain or stairs, compare against the legged Ultra and Ultra+.
- Confirm the "+" configuration. Ask for the Ultra-W+ datasheet to see exactly what the higher tier adds over the standard Ultra-W, including compute, sensors and the included skills package.
- Plan runtime and charging. Patrol schedules depend on battery life. Confirm runtime for your configuration, and plan spare batteries or docking where available.
- Check weather protection. Confirm the ingress rating before committing to outdoor or wet-weather operation.
- Respect privacy. A patrol robot with cameras and microphones should come with clear notice, defined data retention and access controls under local privacy law.
- Check local radio rules. 5G and other radio modules may need local certification. Confirm the requirements for your country before import.
- Start with a pilot. Prove one route or one site, then expand to a coordinated fleet.

What is the difference between the Ultra-W and the Ultra-W+?
The Ultra-W+ is the higher-tier configuration of the same wheel-legged platform. Confirm its exact additions in the current datasheet.
Should I choose a wheel-legged or a legged Aegis?
Choose the Ultra-W or Ultra-W+ for speed, quiet operation and efficiency over long, mostly flat routes with occasional obstacles. Choose the legged Ultra or Ultra+ for predominantly rough terrain and stairs.
Can the Ultra-W+ be programmed?
Yes. The Ultra-W line supports secondary development, simulation training and multi-robot coordination. Ultra-tier Aegis models offer SDK, API, Isaac Sim, Python and no-code development tools.
Where can I buy the FX Aegis Ultra-W+?

Summary
The FX Aegis Ultra-W+ ends the trade-off between legged reach and wheeled efficiency. Wheels carry it fast and quietly across long routes, and legs carry it over everything a wheeled robot can't climb. As the highest tier of Faraday Future's wheel-legged Aegis line, it brings open development, multi-robot coordination, payload expansion and the company's shared embodied-AI skills ecosystem. For security patrols, property monitoring and research teams that need a quadruped able to cover ground, it is the Aegis built to roll as well as walk.
