I started putting together the trusses needed to articulate the hip and hook two
hips together, and found that this leg design:

needed to be compacted.  I imagine the body truss made of long side rails, that
the hips connected to.  When I started to put the side rails on the above hip,
the rails were too far apart to do decent cross bracing.

I redesigned the hip structure and came up with this hip (front view)

and this view from the back:

I built two of the legs and hooked them together like this:

Giving this view from the outside:

The two legs are in different leg groups, so we can go through the walking
sequence for both groups giving us this picture:

Because of the camera angle and shadows due to flash, it is hard to tell when
legs are raised.  The leg lift is more clear in this picture:

Off to build two more legs to see what we end up with for total length of one
side from hip to hip.  I fear the scale is too large and that the legs will not
be structurally sound.  Only time will tell.

Feedback?

Kevin
