Both Achilles' feet ("The Two Brothers"). The similarities and
differences are apparent. The right foot's
mini u-joints have the qualities of ultra-light-weight, simplicity,
screw-driver manipulation, un-durability,
and cheap (about $2.00 each). The left foot's u-joints have the
qualities of light-weight, simplicity, wrench
manipulation, durability, and expensive ($60.00 each, plus cutting
with hack-saw and welding a nut on
each end). The ultra-tiny u-joint won't hold up to the expected
weight load to be placed on it so it will
have to be replaced. The heavier-duty u-joint should handle the
load (time will tell). The keen observer
will note a severe deficiency in this design: no toes! A special
Digital-Toe is in the works.
