鉴于机器人可能看起来不像人形，因此Skeleton跟踪不会按设计工作。它受过人体骨骼跟踪训练。您必须提出自己的深度计算机视觉来跟踪组成手臂的对象
并找出这些关节将映射的位置

Given the robot probably doesn't look like a human form, the Skeleton tracking would not work by designed. It is trained for Human skeleton tracking. You would have to come up with your own depth computer vision to track the objects that make up the arm and figure out where these joints would map

您可以使用像OpenCV这样的库来帮助对象检测，但仍需要对其进行修改以满足您的要求。

You might be able to use a library like OpenCV to help with the object detection, but this would still need to be modified to fit your requirements.
