pico-tool-track
Curve editing, 3D frame editing, a unified web editor, and frame-rate resampling for humanoid robot motion tracks (track JSON).
Quickstart (PyPI)
# 1. Install uv (once)
curl -LsSf https://astral.sh/uv/install.sh | sh
# 2. Install the tool — everything included, no extras needed
uv tool install pico-tool-track
# 3. Run
pico-tool-track web motion.json # unified editor (curve + 3D skeleton)
pico-tool-track web motion.json --mjcf robot.xml # with an explicit robot model
pico-tool-track curve motion.json # matplotlib curve editor
pico-tool-track resample motion.json --fps 100 # resample to 100 Hz
After installation the pico-tool-track command is available globally.
One-off runs without installing: uvx pico-tool-track web motion.json.
Tools
| Command | Description | Backend |
|---|---|---|
pico-tool-track web [json...] |
Unified editor: spline curve editing + linked 3D skeleton preview | fastapi + mujoco |
pico-tool-track curve <json> |
Joint-angle curve editor with draggable control points | matplotlib + scipy |
pico-tool-track edit <json> |
Per-frame 3D editor with live skeleton preview | viser + mujoco |
pico-tool-track resample <json> |
Frame-rate resampling (integer-multiple up/down) | — |
Notes
- Robot model: pass
--mjcf <file>to preview a skeleton, or load one in the UI via the 🤖 Model button. Without a model the editor starts with an empty floor. - Headless servers: 3D rendering uses MuJoCo offscreen rendering. On a
headless Linux server without GPU, run with
MUJOCO_GL=osmesa. - Data format: input/output is track JSON (
joint_names,fps,num_frames,joint_pos,root_pos_w,root_rot_w,body_names,body_pos_w).
中文说明
提供轨迹(track)JSON 数据的曲线编辑、三维帧编辑、统一 Web 编辑器与帧率重采样, 用于人工调整人形机器人的动作轨迹数据。
安装(PyPI)
curl -LsSf https://astral.sh/uv/install.sh | sh
uv tool install pico-tool-track # 全量安装,所有功能开箱即用
使用
pico-tool-track web motion.json # 统一编辑器(曲线 + 3D 骨架联动)
pico-tool-track web motion.json --mjcf robot.xml
pico-tool-track curve motion.json # 曲线编辑器
pico-tool-track resample motion.json --fps 100
说明
- 机器人模型:通过
--mjcf指定,或启动后点界面 🤖 Model 按钮导入; 不传模型则以空白地面模式启动。 - 无 GPU 服务器:3D 渲染走 MuJoCo 离屏渲染,无显示无 GPU 的 Linux
服务器请用
MUJOCO_GL=osmesa pico-tool-track web ...。 - 版本与更新:
pico-tool-track --version查看版本;uv tool upgrade pico-tool-track升级。
仓库内开发
cd tools/track
uv sync # 安装全部依赖
uv run pico-tool-track web data.json
独立发布(GitHub Releases 一键安装)
除 PyPI 外,也可以用 pico tool release track --upload 生成 wheel +
