The Head DatumThe Head/Body interface is defined on drawing 60. The interface is shown as the bottom edge of the blue ring. This is the datum that defines the base of the Head profile. It could be decieving that the plaster Head includes the Alloy Race but closer inspection shows that materila below the blue ring is marked "WASTE.f"
The Profile of the HeadThe Head is shown on all of the production drawings as being the same diameter as the Body. This would make the minor axis of the profile 9-1/8". Measuring from the bottom edge of the blue ring per the definition on drawing 60, the height of the Head is 10-5/8".
The Final Production Drawing SetFrom the front elevation drawing there are 8 drawings that are referenced that are specific to the definition of the body.
The OpenR2 digital twinThe drawings do not specify the construction method. From production photos, its documented that the body builds started with a wooden mockup, then progressed to a fiberglass prototype, then was contracted to the discarded aluminum build, and then finally the aluminum build seen in the film.
The Body ShapeThe body is a cylinder with a height dimensioned at 1' 7-5/8" or 19-5/8". This dimension appears on the front elevation Drawing 67 - Sheet 1.
The Body SymmetryThe vertical body symmetry is based on 5-3/4" symmetric and mirrored dimension that defines the opening for the Mechanical Arms in the front of the body as well as the opening for the Removable Back Panel on the rear of the body. This divides the body into four zones of symmetry. This dimension appears on the cross-sections Drawing 68* and Drawing 69*.
The Body BalanceThe bodies balance is established by the placement of the Leg Assembly pivot. This pivot is dimension at 4" below the theoretical top of the body. The practical distance to the top edge of the body skin would be 3-7/8". This dimension appears on the front elevation Drawing 67 - Sheet 1.
The Ground LineThe ground line to the bottom of the body measures 11" on drawing 67 sheet 1. This would put the shoulder pivots at 26-5/8" above the ground plane.
Nuetral Ankle PositionThis results in the top of the ankle being positioned on the vertical center of the octagon port and the rest of the lowest row of panels. This respresents the neutral design position of the body when the middle foot is retracted.
