...of the functional prototype of Vlad's Hexabot - the basis of the BuckyBot's spyder.  Building to work out the strengths/weakenesses of the spyder design;  get a single arduino to move ALL the legs: and figure out how to make a hexapod do the "hula" .  The "hula" is a spyder motion in which it moves laterally in X and Y without moving the platform in Z (the vertical axis).
