I try to get joint torque with dc.get_dof_effort() but I cannot get the torque.
I can get the position and velocity.
Why dc.get_dof_effort() not work?
dc = _dynamic_control.acquire_dynamic_control_interface()
dof_ptr = dc.find_articulation_dof(art, joint_name[index])
print(dc.get_dof_effort(dof_ptr)) # always print 0.0
