Assuming 50-75% efficient mechanism your power draw would be:
333-500 Watts.
That is a lot of power draw, but not unheard of.
Add in the use of hybrid mechanisms (use pneumatics, motors & constant-force springs through the use of creative cabling) and the instantaneous electrical power requirement is greatly reduced.
