the speed and force will be limited by
the weight of the sphere,
and the energy required be higher if
inner surface to movement.
whereas the ring,
speed only limited by the power of the motor,
which may result to sudden burst of movements.
however the mechanism for sudden breaks
may wear down the machine quickly
if not properly thought of......
underwater, if outer shell plastic,
then piston inside, octopus-like movement.
depth however may need to be controlled by
submarine-like mechanism, water pressured in/out.
but said can also work with metal.....
i've seen it from alyssa's relay
someone thought of using it like jellyfish?
maybe above setup could work but i think
there are more efficient way to go about these depths
unless aiming to explore absolute bottom depths of the ocean.....
i don't know.
i have no idea what is going on out there.
i just hope people don't mislead on the relays.
i must continue with work,
but resource depletes fast and i am unwell.
opportunities missed on equipment purchase as i cannot travel.
no help ever given.
what use are the rewards if i get really sick.......
need rest for now.........
