so i had this idea for a tiny robot:
make a 2 motor beam walker, but instead of placing the servos at the usual angle, keep them perfectly level
and then give it piezo buzzers for feet.
feet moving forward would be buzzing so as to reduce friction, while the rear moving legs are not buzzing
so they have more grip.
this way the bot would kind of scate across slick surfaces.
will it?
does a piezo buzzer thingy create strong enuff vibrations for a significant grip reduction?
also:
if this is at all possible, is it feasible?
can i produce enuff vibrations to get the job done without having to pack
so many batteries that the weight of those will render it useless again?
if i attach things to the buzzer for a contact surface between the buzzer and the floor,
would the vibrations be transferred, or would the buzzer just fail?

another idea i had was to build a hovercraft with a fan + compartment for weight reduction, a fan horizontally on top
for forward/reverse and use stationary buzzers to steer using the same low/high drag principle.
could that work?
could i use a BEAM circuit to route feedback from the buzzers back to the fan so it adjusts itself to reduce
pressure on the piezos so as to maintain a stable reduced weight, in spite of changes in the surface or damage to the
air compartment?
if not, can it be done with arduino?
