SONIC：MotionBricks 的动作遇上真 G1
MotionBricks 回答「这个角色下一步该做什么？」。GEAR-SONIC 回答「让一台 30 kg 的机器人真的做到」。两者发布在同一个仓库里，README 明确说它们共同构成 NVIDIA GR00T Whole-Body Control 计划的基石。
两个项目如何关联
README 的 Related Work 一节用一句话说清：「Together with MotionBricks, GEAR-SONIC anchors NVIDIA's GR00T Whole-Body Control initiative.」（与 MotionBricks 一起，GEAR-SONIC 奠定了 NVIDIA 的 GR00T Whole-Body Control 计划。）落到实处的含义是：一个共享单仓库（NVlabs/GR00T-WholeBodyControl），MotionBricks 作动作生成层（潜在模型怎么工作），SONIC 作跟踪控制器，把参考动作变成 Unitree G1 上的电机行为。

三个 checkpoint
逐字摘自 GR00T-WBC 模型卡——每个 checkpoint 都在 nvidia/GEAR-SONIC Hugging Face 仓库里：
| Checkpoint | 参考 lookahead | 用途 | 下载 |
|---|---|---|---|
| Default SONIC (original release) | 10 future frames at 20 ms spacing, approximately 200 ms of reference lookahead | Default general-purpose SONIC controller for motion tracking, planning, teleoperation, and compatibility with existing deployments. G1 and teleoperation future-reference observations use step5. | nvidia/GEAR-SONIC · main |
| Low-latency teleoperation | 4 future frames at 20 ms spacing, approximately 80 ms of reference lookahead | Intended for more responsive whole-body teleoperation and VLA execution. G1 and teleoperation future-reference observations use step1. Use its encoder, decoder, and observation config together. | nvidia/GEAR-SONIC · low_latency |
| SONIC v1.1 | 10 future frames at 20 ms spacing, approximately 200 ms of reference lookahead | Uses robot-heading-normalized target orientation and was trained with wrist-pose augmentation. Intended for heading-stable whole-body teleoperation and SONIC-backed VLA policies that use this controller. G1 and teleoperation future-reference observations use step5; this is not the low-latency model. | nvidia/GEAR-SONIC · sonic_v1_1 |
