I tried to understand the point of your reply but Im not sure what your point was - I only seemed to glean "its easier to balance if the operator is moving it".
Please elaborate unless Im being thick.
EDIT > I upvoted your comment in any case as Im sure its helping
It's that there's nothing special about blending "operator initiated animation commands" with the RL balancing system. The balance system has to balance anyway; if there was no connection between an operator's wave command and balance, it would have exactly the same job to do.
At best the advantage of connecting those systems is that the operator command can inform the balance system, but there's nothing novel about that.
'control system' in this case is not implying remote control, it's referring to the feedback system that adjust the actuators in response to the sensed information. If the motion is controlled automatically, then the control loop can in principle anticipate the motion in a way that it could not if it was remote controlled: i.e. the opposite, it's easier to control the motions (in terms of maintaining balance and avoiding overstressing the actuators) if the operator is not live puppeteering it.
