GEAR-SONIC: Supersizing Motion Tracking for Natural Humanoid Whole-Body Control

Name: nvidia/GEAR-SONIC
Brand: nvidia
Rating: 0.0 (38 reviews)

Model Description

SONIC (Supersizing Motion Tracking) is a humanoid behavior foundation model developed by NVIDIA that gives robots a core set of motor skills learned from large-scale human motion data. Rather than building separate controllers for predefined motions, SONIC uses motion tracking as a scalable training task, enabling a single unified policy to produce natural, whole-body movement and support a wide range of behaviors.

Key Features

🤖 Unified Whole-Body Control: Single policy handles walking, running, crawling, jumping, manipulation, and more
🎯 Motion Tracking: Trained on large-scale human motion data for natural movements
🎮 Real-Time Teleoperation: VR-based whole-body teleoperation via PICO headset
🚀 Hardware Deployment: C++ inference stack for real-time control on humanoid robots
🎨 Kinematic Planner: Real-time locomotion generation with multiple movement styles
🔄 Multi-Modal Control: Supports keyboard, gamepad, VR, and high-level planning

VR Whole-Body Teleoperation

SONIC supports real-time whole-body teleoperation via PICO VR headset, enabling natural human-to-robot motion transfer for data collection and interactive control.

Walking	Running

Sideways Movement	Kneeling

Getting Up	Jumping

Bimanual Manipulation	Object Hand-off

Kinematic Planner

SONIC includes a kinematic planner for real-time locomotion generation — choose a movement style, steer with keyboard/gamepad, and adjust speed and height on the fly.

In-the-Wild Navigation

Run	Happy

Stealth	Injured

Kneeling	Hand Crawling

Elbow Crawling	Boxing

Quick Start

📚 See the Quick Start Guide for step-by-step instructions on:

Model Checkpoints

All checkpoints (ONNX format) are available directly in this repository. Inference is powered by TensorRT and runs on both desktop and Jetson hardware.

Checkpoint	File	Description
Policy encoder	`model_encoder.onnx`	Encodes motion reference into latent
Policy decoder	`model_decoder.onnx`	Decodes latent into joint actions
Kinematic planner	`planner_sonic.onnx`	Real-time locomotion style planner

Quick download (requires pip install huggingface_hub):

from huggingface_hub import snapshot_download
snapshot_download(repo_id="nvidia/GEAR-SONIC", local_dir="gear_sonic_deploy")

Or use the download script from the GitHub repo:

python download_from_hf.py             # policy + planner (default)
python download_from_hf.py --no-planner # policy only

See the Download Models guide for full instructions.
