spindly
legs
I attached the leg prototypes to see if the joints were strong enough.
under
compression
I had to beef up the thigh worm joint a bit with a longer shaft and more
bushings. If you look closely you can also see that the axle twists a good 30
degrees under load. Thanks to hovercraft skirt footpads, there’s enough
traction to keep the joints from getting too stressed.
more beef
The open face joint design could allow for attachment to the body through the
face of the gear at the four pin holes, eliminating the central axle twist
(my fallback design) but it isn’t necessary for this model.
knobby
knee
Doubled up AT-AT knee hinges work well for the knee joints, and I might want
to leave the interesting circular face exposed.
Next I’ll apply a skin to the lower legs. I’m wondering though if the contest
picture mecha really has practical footpads. I don’t see how it can really
walk well, unless the heel retracts, or the lower foot can bend upwards.
Looks like the front leg armor plate might cover a big hydraulic piston.

Sweet! I really like the way you concealed the worm gear joints in the legs. I
guess I couldn’t tell before whether or not worm gears were used in you model -
I would have been a little disppointed if they weren’t ;-)
Later,

| (...) I also made a prototype with knee worm gears, but I wanted to find at least one effective use for the AT-AT knees (my previous uses were... ineffective). Total worms = 4 legs + 2 shoulders = 6 K (19 years ago, 10-Jan-06, to lugnet.build.mecha, FTX)
