# `sim2real`
|
||||
|
||||
当前版本只部署现在这套 `53D -> 16D` 模型,不再兼容旧版 `crawl`、多策略和历史观测。
|
||||
|
||||
## 当前部署模型
|
||||
|
||||
- 使用文件:`sim2real/policies/model_rough.pt`
|
||||
- 来源文件:`model_2000.pt`
|
||||
|
||||
## 当前 actor 输入
|
||||
|
||||
- 单帧 `53D`
|
||||
- 顺序:
|
||||
- `base_ang_vel * 0.25`
|
||||
- `projected_gravity`
|
||||
- `command`
|
||||
- `joint_pos_rel`(12)
|
||||
- `joint_vel_rel * 0.05`(12)
|
||||
- `wheel_vel * 0.05`(4)
|
||||
- `last_actions`(16)
|
||||
|
||||
不包含:
|
||||
|
||||
- `base_lin_vel`
|
||||
- `height_scan`
|
||||
|
||||
## 当前控制参数
|
||||
|
||||
- 控制频率:`50Hz`
|
||||
- 站立保持:`startup/stand_balance.py`
|
||||
- `hip_abduction` 缩放:`0.125`
|
||||
- 其他腿关节缩放:`0.25`
|
||||
- 轮速缩放:`5.0`
|
||||
- 腿 LPF:`5Hz`
|
||||
- 轮 LPF:`15Hz`
|
||||
- 零命令抑制:默认开启,可通过 `config.yaml > policy.enable_zero_cmd_suppression` 关闭
|
||||
- 零命令保持:默认开启,可通过 `config.yaml > policy.hold_zero_command_pose` 控制
|
||||
- 首次命令解锁:默认开启,可通过 `config.yaml > policy.require_active_command_to_release` 控制
|
||||
|
||||
## 当前站立逻辑
|
||||
|
||||
- `startup`:从实测姿态过渡到默认站姿
|
||||
- `stand_balance`:根据 `IMU roll/pitch + gyro` 动态修正四条腿目标
|
||||
- `runtime`:只有站立稳定后才进入策略控制
|
||||
|
||||
这次改动的重点是:策略不再承担“先把身体撑住”的职责。
|
||||
|
||||
另外当前部署逻辑改成:
|
||||
|
||||
- 零命令时默认不让策略直接接管腿和轮,保持站立目标
|
||||
- 命令从零变为非零时,策略输出在 `command_release_s` 内平滑放开
|
||||
|
||||
## 启动命令
|
||||
|
||||
默认前提:当前目录就是 `sim2real/`
|
||||
|
||||
纯 `python`:
|
||||
|
||||
```bash
|
||||
python -m pip install -r requirements-orin.txt
|
||||
python tools/alignment_check.py --policy policies/model_rough.pt --manifest deployment_manifest.yaml
|
||||
python tools/standalone_check.py
|
||||
python main.py --dry-run
|
||||
python main.py
|
||||
python web/server.py --host 0.0.0.0 --port 8080
|
||||
```
|
||||
|
||||
Windows 本机:
|
||||
|
||||
```bash
|
||||
D:\Minicoda3\envs\py10\python.exe -m pip install -r requirements-orin.txt
|
||||
D:\Minicoda3\envs\py10\python.exe tools\alignment_check.py --policy policies\model_rough.pt --manifest deployment_manifest.yaml
|
||||
D:\Minicoda3\envs\py10\python.exe tools\standalone_check.py
|
||||
D:\Minicoda3\envs\py10\python.exe main.py
|
||||
D:\Minicoda3\envs\py10\python.exe web\server.py --host 0.0.0.0 --port 8080
|
||||
```
