Output Formats

FBX output

AIMoCap currently produces FBX animation output for:

• the built-in default target
• published custom humanoid characters

This FBX output is character animation data. It is suitable for downstream review, cleanup, retargeting, and scene integration in tools such as:

• Maya
• MotionBuilder
• 3ds Max
• Unity
• Unreal Engine

Robot motion data

Robot motion output currently supports:

• Unitree G1

More robot targets are planned for later updates.

If you need custom robot adaptation, contact support@aimocap.net.

Mujoco JSON structure

The Unitree G1 robot output is a Mujoco-oriented JSON motion file.

A simplified example looks like this:

{
  "version": 1,
  "robotType": "unitree_g1",
  "fps": 30,
  "frameCount": 120,
  "root_pos": [[0.0, 0.0, 0.79]],
  "root_rot_xyzw": [[0.0, 0.0, 0.0, 1.0]],
  "dof_pos": [[0.0, 0.1, -0.2]]
}

Field reference:

• version: format version
• robotType: robot identifier
• fps: motion sampling rate
• frameCount: total frame count
• root_pos: per-frame robot base translation
• root_rot_xyzw: per-frame robot base rotation quaternion in xyzw order
• dof_pos: per-frame joint position array

In practice, this file represents a frame-by-frame sequence of:

• robot base position
• robot base orientation
• joint positions

It is intended for downstream Mujoco and robot motion pipelines rather than DCC character animation tools.
