Subject: [alt-beam] Symets with legs


I've looked around at a ton of different symets, and found that aside from
the simple designs, there are more complex ones which use legs. I've
experimented around with some short 1 in copper wires with washers hot glued
to the end for feet, and haven't been very pleased with its overall
performance. How exactly should the legs act in conjunction with the motor
shaft actuator?

This is totally dependant on the resistor values that
you are using.. My beamant has a left-right waggle
with about the same timing as a standard bicore with
.22uF caps and a 1.5 M resistor, and it is
aggressively phototropic in a wide variety of light
conditions.
if you'd lke, I can post the resistor values on my bot
when I get home tonight.. Otherwise, experiment with
lots of different values and use the combination that
is best for the conditions that your bot will be
operating in.

But seriously, try to think about the smoother motion imparted to legs
when a motor is moving them against the flip-flop between two extremes
from magnet push/pull.

really at efston? i would have thought at active surplus on queen st.

interesting.

thanks
