+# 第一代软件闭环
+
+第一代 16DOF 软件的目标是先打通“训练、仿真验证、真机执行”闭环，而不是在初期建立复杂的分布式系统。
+
+## 训练与策略
+
+`05_software/train/rc_mjlab` 使用本地修改的 mjlab 和 MuJoCo 模型训练轮腿混合策略。训练任务包括 Flat、Rough 和 Crawl，腿部 12 个关节输出位置目标，4 个轮子输出速度目标。
+
+## MuJoCo 与 Sim2Sim
+
+- `mujoco_sim` 用于不加载 RL 策略时的模型、动力学和控制调试。
+- `sim2sim` 加载训练策略，在独立 MuJoCo 环境中验证观测、动作、地形和导航行为。
+- 两者与训练任务共同使用 `rc_mjlab/mjcf`，避免早期模型定义不一致。
+
+## 真机控制
+
+- `ik_real` 先以逆运动学和轨迹插值验证电机控制链路。
+- `sim2real` 再将训练策略部署到 Python 真机运行时，加入 IMU、站立、安全和 Web 调试。
+
+## 阶段特点
+
+这一版本的优势是链路完整、模块直观，便于快速验证；局限是训练、仿真和部署仍存在重复资源，Python 真机运行时的实时性和系统集成能力有限。这些问题推动了后续统一训练版本和 ROS 2/C++ 部署架构。

+## 模型契约

+- `obs_dim = 53`
+- `action_dim = 16`
+- 单帧输入
+- 无 `base_lin_vel`
+- 无 `height_scan`
+
+## 启动流程
+

+2. 使能电机
+3. 从当前实测姿态起立
+4. 进入 `stand_balance` 闭环站立
+5. prime 当前观测
+6. 进入 `50Hz` runtime
+
+## 为什么这样改
+
+- 之前版本在 `startup` 后只维持固定 `STAND_POSE`
+- 实机上纯 PD 不足以持续抗姿态扰动
+- 现在增加独立站立闭环，先保证身体支撑，再进入策略
+
+## 运行开关

+- `crawl` 模型
+- 多策略切换
+- `318D` 历史输入
+- 旧版 `startup.start_pose`

+
+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

+# rc_mjlab
+
+基于 [mjlab](https://github.com/google-deepmind/mjlab) 框架的四轮腿混合机器人强化学习训练与部署部署项目，面向机器人竞赛场景（如越障、匍匐、斜坡、台阶等复合任务）。
+
+---
+
+## 🛠️ 项目简介
+
+本项目针对一台 **4 腿 × 3 关节 + 4 驱动轮（轮腿混合）** 的移动机器人，在 MuJoCo 物理引擎中利用 PPO 算法进行多任务运动控制策略训练。
+
+系统设计特点包括：
+1. **高保真动力学步进**：物理仿真计算步长设为 **`2ms` (0.002s)**，为碰撞、地面力学传递提供极高的解算频宽与稳定性。
+2. **50Hz 控制决策循环**：通过在环境中设置 `decimation = 10`，策略决策周期为 `20ms` ($0.002\text{s} \times 10 = 0.02\text{s}$)，即控制决策频率为 **`50Hz`**，完全对齐真机控制周期。
+3. **混合滤波执行器**：
+   - 腿部 12 个位置控制关节采用位置 PD 伺服（$K_p=40, K_d=1$），并叠加截止频率为 **`5Hz`** 的低通滤波器进行动作平滑，减小高频机械抖动。
+   - 轮部 4 个速度驱动关节采用阻尼速度伺服（$K_d=0.5$），叠加截止频率为 **`15Hz`** 的低通速度滤波器，保证转速响应的灵敏度。
+4. **大规模并行加速**：利用 GPU 并行（通过 Warp 和 MuJoCo GPU 物理管线），支持最多 $4096$ 环境同时训练，并包含对动作变化率、关节加速度的惩罚项以平抑噪声。

+
+## ⚖️ 奖惩体系设计 (Robot-Rough-v0)
+
+复杂地形任务采用 **“仅正奖励截断”** 机制（即每步累加的总奖励若小于0则强制截断为0），防止机器人在困难关卡早期选择倒下自杀来规避负惩罚。
+
+### 1. 运动追踪与状态惩罚
+
+| 奖励/惩罚项 | 权重 (Weight) | 适用函数 / 物理意义 |
+|---|---|---|
+| **track_lin_vel** | `+4.5` | L1 范数水平线速度跟踪奖励，平缓高速漂移 |
+| **track_ang_vel** | `+2.0` | 偏航角速度指数跟踪奖励 |

+| **leg_joint_acc_l2** | `-2.5e-7` | 限制腿部 12 关节**角加速度**，直接抑制关节高频电磁和机械震荡 |
+| **wheel_joint_acc_l2** | `-2.5e-9` | 限制 4 个驱动轮的**角加速度**，平缓轮速切换，降低打滑振荡 |
+| **joint_pos_limits** | `-0.2` | 极度接近关节极限限位阻挡时的硬惩罚 |
+
+### 3. 接触反射与安全约束
+
+| 奖励/惩罚项 | 权重 (Weight) | 适用函数 / 物理意义 |

+

+
+## 🌀 域随机化 (Domain Randomization)
+
+为了使训练的控制策略具有卓越的零样本真机部署能力，在环境重置及仿真运行中注入了高强度的域随机化参数：
+
+| 随机化项目 | 扰动操作 | 随机范围 |
+|---|---|---|
+| **机身质心偏移 (base_com)** | 加法 | X, Y, Z 三轴分别随机偏置 `[-0.05, 0.05]` 米 |
+| **角度传感器零偏 (encoder_bias)** | 加法 | 关节传感器绝对偏置 `[-0.015, 0.015]` rad (约 $\pm 0.85^{\circ}$) |
+| **几何表面摩擦力 (body_friction)** | 绝对值 | 地面及机器人碰撞几何体摩擦力在 `[0.3, 1.2]` 均匀随机 |
+| **关节摩擦阻尼 (joint_friction)** | 乘法 | 所有旋转轴关节运动阻尼摩擦在原值的 `[0.7, 1.3]` 倍间随机 |

+| **一阶低通持续风阻 (continuous_disturbance)** | 连续 | 机身持续叠加随机外力（±15N）与力矩（±10Nm），低通周期 0.5s |
+
+---
+
+## 🏆 多地形关卡难度控制 (Robot-Rough-v0)
+
+共有 8 种子地形按照比例混合，通过自适应升级距离控制关卡难度的推进：
+
+| 地形名称 | 混合比例 (Proportion) | 最大配置难度 |
+|---|---|---|
+| **平地 (flat)** | `5%` | 作为初始安定性恢复区域 |
+| **金字塔台阶 (pyramid_stairs)** | `25%` | 最大阶梯高度上限 `0.30` 米，级宽 0.30m |
+| **倒金字塔台阶 (pyramid_stairs_inv)** | `10%` | 最大倒台阶高度上限 `0.30` 米，级宽 0.30m |
+| **随机高度网格 (random_grid)** | `10%` | 最大网格方块起伏上限 `0.30` 米 |
+| **随机粗糙地形 (random_rough)** | `5%` | 地表最大颗粒随机噪声起伏 `0.06` 米 |

+| **越障高墙地形 (rc_wall)** | `25%` | 自定义跳跃垂直高墙，最大墙高上限 `0.45` 米 |
+| **平台斜坡地形 (sloped_terrain)** | `15%` | 最大坡度限制 `0.325` (约 $18.5^{\circ}$) |
+
+> **地形升级规则**：当机器人朝指令方向行进距离超过当前地块的一半（4米），且实际行进距离大于速度指令对应期望距离的 45% 时，该环境关卡等级 +1。  
+> **地形降级规则**：当指令速度大于 0.1m/s 但实际行进距离小于期望距离的 25%，或者实际移动不足 2.0米时，环境难度等级 -1。
