FX Navi Embodied AI Quadruped Robot
Most robot dogs for sale are finished products: you unbox them, run the demos and look for the next trick. FX Navi works the other way around. It's a robot dog you learn with. You write code, check it in simulation, send it to a real four-legged robot and watch it move. Then you change the head, the skin or the behavior and do it again. If you want to buy a robot dog that teaches as much as it performs, Navi was built for that job.
Navi's most distinctive idea is also its simplest: a smartphone becomes its brain. Slot an iOS or Android phone into the head module, and the phone's processor, camera and microphone give Navi its senses. The robot body supplies the movement and the phone supplies the perception. That's what keeps Navi one of the most accessible learning quadrupeds for sale, and the robot's intelligence can grow as phones improve.
Background
Part of Faraday Future's robot family
Faraday Future launched FX Navi in June 2026 and opened sales and deliveries immediately. It's part of FF's "EAI Robot World", a family of embodied-AI robots that includes:
- the Futurist, Master and Nova humanoids
- the Aegis and Navi quadruped lines
- the Faber mobile manipulator
Within that family, the Aegis line covers security, patrol and professional field work. Navi is the entry point: the foundational learning robot for homes, classrooms and makers.
Built around an education strategy
Navi is the hardware core of FF's robotics education ecosystem, which combines a physical robot, coding tools and curriculum content. Skill and curriculum packages are shared across FF's robot lineup. When a school buys FX Navi today, what students learn carries over to FF's larger robots later.
Design and Movement
12-DoF dynamic motion
Navi uses a 12-degree-of-freedom structure, three per leg, driven by 12 joint motors. Dynamic gait balancing keeps it steady while it walks, trots and turns, and its motion parameters can be adjusted for experiments. According to its published specifications, Navi reaches speeds of up to 2 m/s and rotates at up to 360° per second. That's genuine agility for a robot dog in its class.
Light and classroom-friendly
At about 8 kg, Navi is easy to carry between rooms, lift onto a table for programming and store at the end of the day. Teachers who buy several units for a classroom can move them without a cart.
A body designed to be customized
Navi pairs a neutral chassis with a soft bionic body wrap, so it can be dressed in creative skins. Faraday Future has opened the 3D model files for the head, which means students can design and 3D-print their own head modules. Few robot dogs for sale invite this level of personalization, and here a design project and a robotics project become the same assignment.
The Smartphone Brain
Instead of building in an expensive sensor and computer stack, Navi uses the device most people already own. When a phone is slotted into the head module:
- the camera gives Navi vision
- the microphone lets it hear voice input
- the phone's processor runs its perception and interaction features
Both iOS and Android are supported. Navi also offers app connectivity and remote control, and comes with a handheld remote.
Faraday Future positions Navi as a true embodied-AI robot that becomes more capable with use. It has also announced over-the-air updates for capabilities such as autonomous following and multimodal perception. Treat these as roadmap features and confirm current availability when you buy.
Learning Ecosystem
Code, simulate, deploy
Navi's coding workflow follows the same path professional robotics teams use:
- Write a program with FF's Brain Blocks tools.
- Validate it in simulation before touching hardware.
- Deploy it to the physical robot and observe the result.
Testing in simulation first means fewer crashes, faster iteration, and a clear way to understand why a behavior works or fails. It's the main reason educators buy FX Navi instead of a toy robot dog.
Open development interfaces
For older students, makers and researchers, Navi provides open development interfaces and tools for exploring robotics and AI beyond the guided curriculum.
Skills and curriculum packages
Optional packages are for sale alongside the robot:
- Premium Skills: additional behaviors.
- Curriculum Skill: structured STEM course content for project-based learning.
- Dog-head package: an add-on head module.
Because these packages are shared across FF's lineup, they aren't exclusive to Navi. Buy them once and the learning carries forward.
Performance and Practical Limits
Navi is built for learning, not for field work. Before you buy, it's worth being clear about its envelope:
- Terrain: designed primarily for indoor, flat-ground use, such as classrooms, labs, living rooms and hallways.
- Obstacles: its published specifications list obstacle clearance of up to 34 cm.
- Runtime: a built-in lithium battery provides about two hours of continuous operation, enough for a lesson or a coding session.
- Charging: direct charging from the included charger.
For outdoor patrol, weather resistance, heavy payloads or long runtimes, the Aegis line is the right robot dog to buy.
What's in the Box
- FX Navi quadruped robot
- Charger
- Remote controller
A compatible iOS or Android smartphone is required for the head module and isn't included.
Who Should Buy FX Navi
- Schools and STEM programs: a hands-on platform for project-based learning in coding, robotics and AI. Many schools buy several units so students can work in teams.
- Families and young creators: a robot dog that grows with a child's skills, from remote driving to writing their own programs.
- Makerspaces and clubs: 3D-printed heads, custom skins and open interfaces for creative projects.
- University intro courses and researchers: a low-cost quadruped for locomotion experiments and sim-to-real exercises before buying larger platforms.
FX Navi vs. FX Aegis: Which Should You Buy?
| FX Navi | FX Aegis series | |
|---|---|---|
| Primary role | Learning, STEM, creative projects | Security, patrol, companionship, professional development |
| Brain | Your smartphone, in the head module | Onboard computing (Orin NX on Ultra models) |
| Environment | Indoor, flat ground | Indoor and outdoor; Ultra models rated IP54 |
| Weight | About 8 kg | About 15–22 kg depending on model |
| Buy it for | A first robot, classrooms, makers | Properties, sites and advanced development |
Before You Buy: Planning Tips
- Pick the phone first. Make sure each robot has a compatible, charged smartphone assigned to it, ideally a dedicated device for classroom use.
- Plan for two-hour sessions. Schedule charging between classes, or buy extra units to rotate.
- Set up a clear floor area. Navi works best on flat indoor surfaces with space to move.
- Start in simulation. Teach students to validate code virtually before deploying, to protect both the robot and the lesson plan.
- Add a 3D printer. Head design projects are one of Navi's most engaging features.
- Bundle the packages. If you're buying for a school, add the curriculum package at purchase so lessons are ready on day one.
