- Add MindRobotDualArmIKAbsEnvCfg: standalone dual-arm env inheriting ManagerBasedRLEnvCfg directly (no single-arm dependency), 20D action space (left_arm7 | wheel4 | left_gripper1 | right_arm7 | right_gripper1) - Add local mdp/ with parameterized gripper_pos(joint_names) to support independent left/right gripper observations without modifying IsaacLab - Update teleop_xr_agent.py for dual-arm mode: shared XrClient to avoid SDK double-init crash, root-frame IK command caching so arm joints are locked when grip not pressed (EEF world pos still tracks chassis) - Tune mindrobot_cfg.py initial poses with singularity-avoiding offsets - Add CLAUDE.md project instructions and debug_action_assembly.py Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

# MindBot Project
|
||
|
||
基于 Isaac Lab 的移动操作机器人(MindRobot)仿真学习框架,支持强化学习(RL)和模仿学习(IL)。
|
||
|
||
## 环境要求
|
||
|
||
- **Isaac Sim**: 5.1.0
|
||
- **Python**: 3.11
|
||
- **依赖**: isaaclab, isaaclab_assets, isaaclab_mimic, isaaclab_rl, isaaclab_tasks
|
||
- **Conda 环境**:
|
||
- `env_isaaclab` — 主开发环境
|
||
- `xr` — 另一个同样包含 isaaclab/isaacsim 的环境,两者均可运行 Isaac Lab 脚本
|
||
|
||
**IMPORTANT**: 所有 Isaac Lab 脚本必须通过 `~/IsaacLab/isaaclab.sh -p` 启动,直接用 `python` 会报 `KeyError: 'EXP_PATH'`(该变量只有 `isaaclab.sh` 会在启动时设置)。
|
||
|
||
```bash
|
||
# 安装包
|
||
~/IsaacLab/isaaclab.sh -p -m pip install -e source/mindbot
|
||
```
|
||
|
||
## 关键环境变量
|
||
|
||
```bash
|
||
export MINDBOT_ASSETS_DIR=/home/tangger/LYT/maic_usd_assets_moudle # USD 资源路径(默认值)
|
||
```
|
||
|
||
## 常用命令
|
||
|
||
```bash
|
||
# 列出所有注册环境
|
||
python scripts/list_envs.py
|
||
|
||
# 测试环境(零动作 / 随机动作)
|
||
python scripts/zero_agent.py --task Template-Mindbot-v0 --num_envs 4
|
||
python scripts/random_agent.py --task Template-Mindbot-v0 --num_envs 4
|
||
|
||
# RL 训练(RSL-RL PPO)
|
||
python scripts/rsl_rl/train.py --task Template-Mindbot-v0 --num_envs 4096
|
||
|
||
# RL 推理
|
||
python scripts/rsl_rl/play.py --task Template-Mindbot-v0
|
||
|
||
# 遥操作(Spacemouse / 键盘)
|
||
python scripts/environments/teleoperation/teleop_se3_agent.py --task Isaac-MindRobot-LeftArm-IK-Rel-v0
|
||
|
||
# 遥操作(XR 设备)
|
||
python scripts/environments/teleoperation/teleop_xr_agent.py --task Isaac-MindRobot-LeftArm-IK-Rel-v0
|
||
|
||
# 代码格式化
|
||
pre-commit run --all-files
|
||
```
|
||

||
## 新增任务的规范
|
||
|
||
### RL 任务结构
|
||
```
|
||
tasks/manager_based/rl/<task_name>/
|
||
├── __init__.py # gym.register(id="<TaskId>-v0", ...)
|
||
├── <task_name>_env_cfg.py # ManagerBasedRLEnvCfg 子类
|
||
├── agents/
|
||
│ └── rsl_rl_ppo_cfg.py # RslRlOnPolicyRunnerCfg 子类
|
||
└── mdp/
|
||
├── rewards.py
|
||
├── terminations.py
|
||
└── __init__.py
|
||
```
|
||
|
||
### IL 任务结构
|
||
```
|
||
tasks/manager_based/il/<task_name>/
|
||
├── __init__.py # gym.register with robomimic_bc_cfg_entry_point
|
||
├── <task_name>_env_cfg.py # ManagerBasedRLEnvCfg 子类(使用 DifferentialIKController)
|
||
└── agents/robomimic/
|
||
└── bc_rnn_low_dim.json # RoboMimic BC 配置
|
||
```
|
||
|
||
新任务的 `__init__.py` 必须在 `mindbot/tasks/manager_based/__init__.py` 中 import 才能注册到 Gym。
|
||
|
||
## 代码风格
|
||
|
||
- 文件头使用 SPDX 许可证注释:`# SPDX-FileCopyrightText: Copyright (c) 2022-2025, The Isaac Lab Project Developers.`
|
||
- 关节角度配置用弧度,注释中可标注对应度数
|
||
- 执行器刚度/阻尼参数调整需在注释中说明物理含义
|
||
|
||
## MindRobot 关节组
|
||
|
||
| 关节组 | 关节名 |
|
||
|---|---|
|
||
| 左臂(6 自由度) | l_joint1 ~ l_joint6 |
|
||
| 右臂(6 自由度) | r_joint1 ~ r_joint6 |
|
||
| 左夹爪 | left_hand_joint_left/right |
|
||
| 右夹爪 | right_hand_joint_left/right |
|
||
| 躯干升降 | PrismaticJoint |
|
||
| 头部 | head_revoluteJoint |
|
||
| 底盘轮子 | front/back revolute joints |
|
||
|
||
## 遥操作数据收集
|
||
|
||
- Isaac Lab 内遥操作脚本使用 `env_isaaclab` 环境
|
||
- XR 设备接入依赖 `deps/XRoboToolkit-Teleop-Sample-Python/`,需切换到 `xr` 环境
|
||
- 示教数据格式兼容 LeRobot / RoboMimic
|
||
- 多相机配置:cam_head, cam_chest, cam_left_hand, cam_right_hand, cam_top, cam_side
