That's why I am here I like such creatures but are not able to design them.. look what I have printed two years ago:


By the way also snap in modules that do not snap securly..

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.

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


Place where I found the "legs" ;-)

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.
