Servos — four paws, Boston-Dynamics-style:
motor 1 = left front paw · motor 2 = right front paw ·
motor 3 = left back paw · motor 4 = right back paw.
Spoken commands: sit, stand, shake, forward, back, spin, dance, stop, good boy.
Sit folds the back legs; stand extends them; shake lifts & waves the right front paw;
forward/back walks with diagonal pairs (Spot-style trot); spin counter-rotates the sides;
dance pulses each paw in a wave. Use the reverse checkboxes below if a motor is wired backwards.
