Question about humanoid robot and dataset

[Shi-Qi-Li]

Hi, thanks for your amazing work and open source the code. I have some question about the humanoid robot and dataset.

1. It seems the humanoid robot is based the UHC but with some modifications, like extra Spine2 joint and the geom type of some body parts are also changed. Are these modifications based on any particular reason?
2. Wheather the data across the whole dataset (ballplay-v and ballplay-m) was collected from the same player?

Any response is appreciated.

Hi, thanks for your attention.

1. The humanoid robot for BallPlay-M is aligned with the skeleton of the Mocap system, which has an extra spine than SMPL-X(ballplay-v) skeleton.
2. Yes, actually I am the player : ), but the resulting skeletons are different due to different mocap technology.
