What sort of upper elements do you anticipate having--precision or "meh, whatever, it's close enough" in terms of motion?

Well the robot is for a sponsor, they will take it to tradeshows and events to advertise their products. so the robot will most likely be facing clean level surfaces with the odd bump every now and again. upper elements wise it will have a humoniod type of structure with a head,shoulders, and arms so leaning toward precision. right now our dimensions are looking to be 34'' by 40'' and about 7-9 feet tall (the upper portion will be very light consisting of mostly sheet metal, so it will be very bottom heavy)
