Welcome to
FX Navi.

FX Navi is a quadruped robot and learning platform designed for STEM and EAI robotics education. Paired with the FX Navi App, dedicated remote controller, companion courses, and developer tools — you can explore robot control, block-based programming, motion choreography, AI interaction, and hands-on robotics project development.

NAVI IS NOT A TOY. CHILDREN 14 YEARS OF AGE AND UNDER MUST BE ACCOMPANIED BY AN ADULT AT ALL TIMES.

  4. Confirm battery level, App connection, and remote controller connection are all normal.
  5. If the issue persists, stop use and contact the support team.
Step 1 · Design

Design.

Use the 3D design software to shape your very own NAVI. Change how it looks any way you like — this is your design!

Step 2 · 3D Print

3D Print.

Now let's bring your design to life. The 3D printer builds your NAVI's top one thin layer at a time.

Step 3 · Color

Color.

Time to make it yours! Grab your acrylic paint and paint your NAVI's top any colors you love.

Step 4 · Build

Build.

Let's put NAVI together. First screw on the base, then connect the rest of the parts and plug NAVI's top onto the base.
