Subject: [alt-beam] Mischevious Walker Problems



Hie,

I dont really know why the angle sweep of the rear leg of my walker are
turning more than the other it is suppose to be turning left and right at
the same angle...ya? but mine no matter how i tune it goes to the right more
than the left which makes the robot falls on its butt or fall down....i
tried using bicore and microcore but the end results is still the
same.....and i tried using springs too it just can make it the same...is it
the electronics or the mechanis...the leg design is very symetry
though..and how do i make the bot adaptive like making it feedback feed
forward or implex......i heard someone saying putting a 470k resistor on the
input and output line of the buffering motor driver to make implex...is that
it?and how do i put multiple inputs of neural nets to my microcore so that
it has a emergent behaviour....thanks(sorrie to bother u guys with so many
questions)

p/s:if i were to build a four motor walker....hows the walking gait like
does it go forward on the forward right motor and the rear left motor and
then backward and vise versa or does it go forward with the forward right
motor and rear left motor and vice versa with the other diagonal pair of
gearmotor...any hints cause i am quite confused here
