how can I find out information about which body part the observation belongs to?

similar to the OpenAI mujoco tasks where they have documentation detailing which dimension of the state corresponds to which part of the physical body, it would be good to be able to have something similar for DMC. If I look at e.g. walker-walk all I get from the time step is an observation with 'orientations', 'height' and 'velocity'. Can I at least find this information out by looking at the source code?

从 walker-walk 任务开始，检查其方向、高度和速度观测值在 DMC 源代码中是如何构建的。记录哪些观测维度对应于身体部位，并确认对于希望从任务输出或源代码中获取这些信息的用户来说，这种映射是易于理解的。
