Tribolite at Thingiverse
This nautilus gear has also a nature inspired design. But an old guy told me that this where common gears for paper cutting machines for example: Slow cutting fast back track without electronics.

Nautilus gear at Thingiverse

I just came from a walk in the park where I "mused" about the leg gear and got some design inspirations gratis

Don't follow my spur gear spleen to fast. But if, the better location for the motor would be in the middle.

Have a look at this sketch (Yes this are "only" 16 legs). If the motor drives all the gear from the front - position A - the forces has to pass 28 gears till it reaches the last leg. If we position it in the middle - position B - it will be only the half of loss and slag to the last leg.

For my opinion this gives us also more space for bumper switches etc. at the front and a better weight distribution.
