Hi, I encounted an issue. When I run a xml file in mujoco, it cann't be static like other normal xml(I didn't choose Pause, just Run) as below image. I want to keep joint as zero just in mujoco, if so I can use it do some experiments, but now I cann't. I tried to change some setup in xml, but no effect. How can I handle with it? Thank you for your advice, truly. The full files can be downloaded from https://github.com/Diankuang-Wu/hithand_xml.git
