Subject: [alt-beam] 2 motor walker


Last night I completed the Nv and motor driver for a basic 2-motor
walker.

I first had it connected to 4 LEDs
(2 for each motor, forward and reverse)

I was curious about the cycle rythm. during the transition phase (when
the front motor stops and the rear motor engages) both the led's for one
motor would be lit simultaneously for about a half of the cycle..

it wasnt until i connected motors to it that i understood why it works
the way it does..

Ive seen other schematics for walkers. Most of them cross connected the
motors from the driver outputs.

this design (Ala Chiu) uses a slightly different configuration (which i
like better)

the procceses overlap in a way that the motor recieves its power from
both "Halves" of the driver in a interesting way.

I just though i would point this out and say HEY nice job =]

HEY nice job =]
