A two-stage telescopic ?spine mast? formed the main component of the structure, providing both support and lift to raise OM to sitting and standing positions. The outer section of the mast effectively acted as the spine, while two extending inner sections acted as a lifting ?prop?.
The mast was attached at its base to a heavy duty pivot mechanism giving approximately 100 degrees of movement and was articulated by a pair of double acting hydraulic actuators. The powered hips, shoulders and neck were attached to the outer section of the main mast whilst the shoulder and head assembly, formed by a steel truss, were attached to the end. The lift into standing position was provided entirely by the main mast to upper part of the body. The legs incorporated no mechanics or power for the show moves but were pulled into place by gravity as the torso lifted, articulated to provide the required dexterity for life-like movement.
The whole figure was mounted on a 1.5 metre high, mobile, self-propelled base located on a 35-tonne modified articulated trailer. In show mode, the trailer extended to 12.8 metres, which stretched OM?s legs out in front of him and contracted to 8.8 metres to draw his legs up into a crouched position before standing.
