Yep, actually most BEAM symets seem to use a trilateral rotational symetery
just as LEM does. So LEM really is a symet in exactly the same way that
Paul Beckingham's Symet-1 is also trilateral symet.
I wonder why I rarely see anything but 1 Nv, trilateral Symets?
(part of my inspiration for building LEM)
But there are many other possible geometeries that can be used, like coaxial
symets
where the motors and caps all have a common axis. This can be combined with
lateral rotational symetery in a suspension system.
As an example, my symet 'Zaraam' uses a hexalateral suspension, with a hexagonal
coaxial capacitor array. The circuitry layer and solar cell 'hood' may not fit
these
symeteries, but the overall design is still described as a Symet in BEAM lingo.
The important detail is only in describing the geometerical symetery, this is
usually
omitted though.
If you want to emulate really efficient, really minimal bioforms, forget
insects.
Look into a drop of pond water under a small microscope.
Symets rule. Most have multiple 'motors', and some are sorts of Turbots. These
bioforms
are far more sucessful than insects, while being much simpler in design.
(None of them are walkers)
This is a much better fit for BEAM tech than trying to emulate insects or
quadripeds.
