This is very close to what I was thinking. if you lowered a plate, lifted the
bot and then rotated it and then rised the plate lowering the bot. With some
clever mechanics you mifgt get the lifting and rotating done with one motor.
I would assign one motor for movement, one switch to count unit distances and
a second motor switch for lifting, rotating. you may need a third motor switch
to do the lift/rotate function.
