The head is a hollow polyurethane form reinforced with a steel plate frame. The Atlas-axis joint, consisting of a polyamide block, allows rotation around a vertical axis and rotation around a horizontal lateral axis.


The neck consists of a core of polyamide elements through which the upper end of the steel spine cable is fed. Around the core elements are 5 polyurethane discs.


The torso is a steel T-shaped frame covered with polyurethane. There is a vertical tube in the torso to accommodate the spine cable. The spine cable consists of threaded steel rods, connected by flexible steel cables.

Lumbar Spine

The lumbar spine assembly consists of a number of polyamide elements representing separate vertebrae. The elements are held together by two strips. The shape of the elements allows for bending of the upper torso in a forward direction but prevents significant rearward and sideward movement.

Lower Torso

The lower torso consists of a glass fiber reinforced polyester frame holding the steel hip tube. The frame is covered with polyurethane. The spine cable holds together the assembly of atlas/axis block, neck, upper torso, lumbar vertebrae and lower torso.

Abdominal Insert

The abdominal insert is a soft open cell polyurethane foam shape that fills the opening at the front of the lumbar spine between the upper torso and the lower torso.


The arms consist of an aluminum and steel frame covered with polyurethane. The upper arms are connected to the shoulder by ball joints. The lower arms are connected to the upper arms by hinge joints.


The legs consist of a polyurethane covered steel and aluminum frame. The upper legs are connected to the hip tube by ball joints. The lower legs are connected to the upper legs by hinge joints.
