+This repository provides a suite of **motion-control evaluation for reinforcement-learning locomotion policies**. The goal is to measure the following aspects of a policy, so we can partially predict Sim2Real performance and reduce the risk of damaging real hardware:
 
-## 支持机器人
-| 机器人型号 | 机器人类型 | 速度追踪指令 |
+- **Robustness**: Under randomized terrains and ground types (e.g., friction / restitution), can the policy keep controlling stably?
+- **Stability**: Are motor outputs reasonable? Does long-horizon execution risk motor overheating? Does it reach extreme joint positions?
+- **Control stability & accuracy**: For velocity-tracking commands, can it track accurately? For target-point commands, how large is the final tracking error?
+
+The evaluation is automated with MuJoCo and implemented fully in Python.
+
+Demo of the evaluation process (4 terrains, 2 difficulty levels):

-## 目录结构
-- `robogauge/scripts`: 启动指标测试程序
-- `robogauge/tasks`: 定义测试任务
-- `robogauge/utils`: 常用工具
+## Usage
 
-## 指标/目标/地形
-指标的计算方法是通过在环境中发送固定指令及持续时长, 通过Mujoco获取所需参数并计算.
+### Run evaluations directly
 
-### 环境参数
-#### 域随机化
-所有的评测指标都会先配置相应的域随机化参数, 在随机参数下进行评测, 以下为常用的域随机化参数
+We provide four evaluation modes: **Single Pipeline**, **Multi Pipeline**, **Level Pipeline**, and **Stress Pipeline**. Compute cost increases gradually, and parallel execution is supported to speed up evaluation. See examples in [CMD.md](./CMD.md).
 
-| 参数名称 | 变量名 | 范围 |
+### Asynchronous evaluation during training
+
+Start the evaluation server:
+
+```bash
+python robogauge/scripts/server.py
+```
+
+Key arguments:
+
+- `--port`: server port (default: `9973`)
+- `--num-processes`: total number of evaluation processes (default: `30`)
+
+The client `robogauge/scripts/client.py` submits evaluation requests to the server and returns results. Example:
+
+```python
+from robogauge.scripts.client import RoboGaugeClient
+
+# Create client and submit a test task
+client = RoboGaugeClient(f"http://127.0.0.1:9973")
+task_id = client.submit_task(
+		model_path=test_payload["model_path"],
+		step=test_payload["step"],
+		task_name=test_payload["task_name"],
+		experiment_name=test_payload["experiment_name"],
+		wait_for_server=True
+)
+
+# Monitor task status and get results
+while True:
+		client.monitor_tasks()
+		for task_id, resp in client.response_data.items():
+				scores = resp['results']['scores']
+				print("[RoboGaugeClient]📊 Scores:")
+				print(json.dumps(scores, indent=2, ensure_ascii=False))
+		client.response_data.clear()
+		time.sleep(5)
+```
+
+Example integration: `update_robogauge` in [`go2_rl_gym - on_policy_runner.py`](https://github.com/wty-yy/go2_rl_gym/blob/f9024e807758d497445857a21dce3b266876f375/rsl_rl/rsl_rl/runners/on_policy_runner.py#L252)
+
+> You can launch training with evaluation enabled via `python legged_gym/scripts/train.py --task=xxx --robogauge`. The trainer waits for the evaluation client to be available. Results are saved under `logs/{experiment_name}` and visualized in TensorBoard.
+
+## Metrics / Goals / Terrains
+
+Metrics are computed by sending fixed commands to the environment for a fixed duration, reading required signals from MuJoCo, and aggregating them.
+
+### Environment Parameters
+
+#### Domain Randomization
+
+All evaluations are run with configured domain randomization (DR). Below are commonly used DR parameters:
+
+| Parameter | Variable | Range |
 | - | - | - |
-| 电机动作执行随机延迟 | `action delay` | `<= RL控制间隔` |
-| base负重 | `base mass` | `-1, 0, 1, 2, 3 kg` |
-| 地面摩擦力 | `friction` | `0.4, 0.7, 1.0, 1.3, 1.6` |
+| Random action execution delay | `action delay` | `<= RL control interval` |
+| Base payload mass | `base mass` | `-1, 0, 1, 2, 3 kg` |
+| Ground friction | `friction` | `0.4, 0.7, 1.0, 1.3, 1.6` |
 
-#### 地形
-1. 支持legged_gym中的部分地形, 包括: `wave, slope, stairs up, stairs down, obstacles, flat`, 除`flat`地形外其他地形可进行难度系数提升
-2. 地面类型 (影响接触摩擦系数, 弹性摩擦系数), 包括: 橡胶地, 木地板, 瓷砖地
+#### Terrains
 
-### 指标
-目前在每个`env.step`后可度量的指标, 所有指标均要求**越大越好**, 目前支持:
+1. Supports a subset of terrains from `legged_gym`, including: `wave, slope, stairs up, stairs down, obstacles, flat`. All terrains except `flat` can be evaluated with increasing difficulty levels.
+2. Ground material types (affecting contact friction / restitution) include: rubber, wooden floor, tile.

-## 创建新任务
-评测任务注册在[`tasks/__init__.py`](./robogauge/tasks/__init__.py)中完成, 包含四个部分:
-- BasePipline: 标准Pipline一般无需修改
-- MujocoConfig: 仿真器配置文件, 一般无需修改
-- BaseGaugeConfig: 指标配置文件, 参考下文创建新指标
-- RobotConfig: 机器人配置文件, 参考下文创建新机器人
-### 新指标
-在`robogauge/tasks/gauge`下创建新的场景、评估指标
-### 新机器人
-在`robogauge/tasks/robots`下创建新机器人、配置控制模型, 参考`go2`配置
-- [go2.py](./robogauge/tasks/robots/go2/go2.py)控制模型, 包含观测构建和动作输出两个函数, 继承`BaseRobot`
-- [go2_config.py](./robogauge/tasks/robots/go2/go2_config.py)配置文件, 包含机器人模型xml路径, 控制模型路径, 观测构建参数, 关节映射顺序, 各类缩放系数, 控制频率等
+## Create a New Task
 
-## 注意事项
-### 导入新机器人/控制模型
-1. 在Robot中创建新的机器人xml文件时, 需包含力矩控制`actuator`, 传感器`sensor - jointpos, jointvel, imu (framequat, gyro, accelerometer)`, 参考[`go2.xml`](resources/robots/go2/go2.xml), **注意: actuator的顺序需要和joint顺序一致, 该顺序称为mujoco关节顺序**
-2. 控制模型相关位置位于[`RobotConfig.control`](robogauge/tasks/robots/base_robot_config.py)中, 不同仿真中关节顺序可能不同, 需保证`mj2model_dof_indices`从mujoco映射到模型训练的关节次序配置正确 (IsaacGym次序和Mujoco相同), 其他模型配置需保持一致
+Tasks are registered in [robogauge/tasks/__init__.py](./robogauge/tasks/__init__.py). A evaluation task consists of four parts:
 
-## 代码架构
-### Pipeline逻辑
+- **BasePipeline**: the standard pipeline (usually no changes needed)
+- **MujocoConfig**: simulator configuration (usually no changes needed)
+- **BaseGaugeConfig**: metric configuration (see below to add new metrics)
+- **RobotConfig**: robot configuration (see below to add a new robot)
 
-[BasePipeline](./robogauge/tasks/pipeline/base_pipeline.py)用于管理仿真`sim`, 度量器(控制指令, 指标计算)`gauge`, 机器人运控模型`robot`三者的调度, 并包含异常处理, 域随机化, 观测噪声的添加.
+### Add a New Metric
+
+Create a new scenario / metric implementation under `robogauge/tasks/gauge`.
+
+### Add a New Robot
+
+Create a new robot implementation and control-model configuration under `robogauge/tasks/robots`. See the `go2` example:
+
+- [go2.py](./robogauge/tasks/robots/go2/go2.py): control wrapper (inherits `BaseRobot`), implements observation construction and action output
+- [go2_config.py](./robogauge/tasks/robots/go2/go2_config.py): config including robot XML path, control-model path, observation params, joint mapping order, scaling factors, control rate, etc.
+
+## Notes
+
+### Importing a New Robot / Control Model
+
+1. When creating a new robot XML, it must include torque-control `actuator` and sensors: `sensor - jointpos, jointvel, imu (framequat, gyro, accelerometer)`. See [resources/robots/go2/go2.xml](resources/robots/go2/go2.xml). **Important**: actuator order must match joint order (this is referred to as the MuJoCo joint order).
+2. Control-model related configuration is in [robogauge/tasks/robots/base_robot_config.py](robogauge/tasks/robots/base_robot_config.py) under `RobotConfig.control`. Joint orders may differ across simulators; ensure `mj2model_dof_indices` correctly maps MuJoCo joint order to the joint order used during training (IsaacGym uses the same order as MuJoCo). Keep other model configs consistent.
+
+## Code Architecture
+
+## Directory Structure
+
+- `robogauge/`: core Python package
+	- `robogauge/scripts/`: runnable entry scripts (run evaluation / start server)
+	- `robogauge/tasks/`: task system (sim config + metrics/scenes + robot + scheduling)
+		- `robogauge/tasks/pipeline/`: scheduling & execution layer (lifecycle, DR, parallel seeds, aggregation)
+		- `robogauge/tasks/gauge/`: gauge layer (command generation, metric computation, result aggregation)
+		- `robogauge/tasks/robots/`: robot adapters (obs/action, joint mapping, model loading, control rate)
+		- `robogauge/tasks/simulator/`: simulator wrappers / environment interfaces (MuJoCo integration, stepping, state access)
+		- `robogauge/tasks/custom/`: project-specific extensions and custom tasks
+	- `robogauge/utils/`: utilities (logging, config/file helpers, stats, math)
+- `resources/`: simulation static assets
+	- `resources/robots/`: robot assets (XML / meshes / textures), organized by robot type
+	- `resources/terrains/`: terrain assets (e.g., `flat.xml`, slope/stairs/wave/obstacle variants)
+	- `resources/models/`: policy/model resources
+- `assets/`: documentation assets
+- `scripts/`: helper shell scripts for running experiments
+
+### Pipeline Logic
+
+[BasePipeline](./robogauge/tasks/pipeline/base_pipeline.py) manages scheduling among the simulator `sim`, the gauge (command generation + metric computation) `gauge`, and the locomotion policy wrapper `robot`. It also includes exception handling, domain randomization, and observation noise.
 
 ![robogauge_basepipeline](./assets/robogauge_basepipeline.png)
 
-[MultiPipeline](./robogauge/tasks/pipeline/multi_pipeline.py)用于多进程启动不同seed, 域随机化参数下的`BasePipeline`, 并合并结果文件.
+[MultiPipeline](./robogauge/tasks/pipeline/multi_pipeline.py) launches `BasePipeline` in multiple processes across different seeds and DR parameter sets, then merges result files.
 
-[LevelPipeline](./robogauge/tasks/pipeline/level_pipeline.py)对于当前的环境配置, 找到环境地形下模型能稳定通过(三个seed均通过)的最高地形难度.
+[LevelPipeline](./robogauge/tasks/pipeline/level_pipeline.py) searches, for the current environment configuration, the highest terrain difficulty that the policy can stably pass (all three seeds pass).

-## 可能的报错
-### Mujoco OpenGL Context Error
+## Common Errors
+
+### MuJoCo OpenGL Context Error
+
 ```mujoco.FatalError: an OpenGL platform library has not been loaded into this process, this most likely means that a valid OpenGL context has not been created before mjr_makeContext was called```
-问题原因: Mujoco在无头模式下无法创建OpenGL上下文
-解决方案: 在`robogauge/scripts/run.py`和`robogauge/scripts/server.py`中, 将`os.environ['MUJOCO_GL']`设置为`egl`(GPU)或`osmesa`(CPU, 慢)
+
+Cause: MuJoCo cannot create an OpenGL context in headless mode.
+
+Fix: In `robogauge/scripts/run.py` and `robogauge/scripts/server.py`, set `os.environ['MUJOCO_GL']` to `egl` (GPU) or `osmesa` (CPU, slower).

+## 创建新任务
+评测任务注册在[`tasks/__init__.py`](./robogauge/tasks/__init__.py)中完成, 包含四个部分:
+- BasePipline: 标准Pipline一般无需修改
+- MujocoConfig: 仿真器配置文件, 一般无需修改
+- BaseGaugeConfig: 指标配置文件, 参考下文创建新指标
+- RobotConfig: 机器人配置文件, 参考下文创建新机器人
+### 新指标
+在`robogauge/tasks/gauge`下创建新的场景、评估指标
+### 新机器人
+在`robogauge/tasks/robots`下创建新机器人、配置控制模型, 参考`go2`配置
+- [go2.py](./robogauge/tasks/robots/go2/go2.py)控制模型, 包含观测构建和动作输出两个函数, 继承`BaseRobot`
+- [go2_config.py](./robogauge/tasks/robots/go2/go2_config.py)配置文件, 包含机器人模型xml路径, 控制模型路径, 观测构建参数, 关节映射顺序, 各类缩放系数, 控制频率等
+
+## 注意事项
+### 导入新机器人/控制模型
+1. 在Robot中创建新的机器人xml文件时, 需包含力矩控制`actuator`, 传感器`sensor - jointpos, jointvel, imu (framequat, gyro, accelerometer)`, 参考[`go2.xml`](resources/robots/go2/go2.xml), **注意: actuator的顺序需要和joint顺序一致, 该顺序称为mujoco关节顺序**
+2. 控制模型相关位置位于[`RobotConfig.control`](robogauge/tasks/robots/base_robot_config.py)中, 不同仿真中关节顺序可能不同, 需保证`mj2model_dof_indices`从mujoco映射到模型训练的关节次序配置正确 (IsaacGym次序和Mujoco相同), 其他模型配置需保持一致

+## 可能的报错
+### Mujoco OpenGL Context Error
+```mujoco.FatalError: an OpenGL platform library has not been loaded into this process, this most likely means that a valid OpenGL context has not been created before mjr_makeContext was called```
+问题原因: Mujoco在无头模式下无法创建OpenGL上下文
+解决方案: 在`robogauge/scripts/run.py`和`robogauge/scripts/server.py`中, 将`os.environ['MUJOCO_GL']`设置为`egl`(GPU)或`osmesa`(CPU, 慢)
