Subject: Re: photopopper
the touch sensors go in series with 680K resistors and
they both go in parallel with the .22 uf capacitors.
heres the idea:
/ <<-touch sensor
+-O O--/\/\/\--+ <<-resistor
| |
---+------||-------+---
capacitor^^^
most touch sensor tutorials include the resistor
inside the sensor, so just attach the two leads to
either side of the capacitor, dont worry about
polarity.
some photopopper circuit diagrams have the touch
sensors in them, some dont.
hope this helps.

13570 Mon, 17 Apr 2000 11:12:32 -0700 (PDT) i swear the circuit's correct!!! beam@sgiblab.sgi.com Evan Dudzik please help save my walker from going to a better (?)
place (the world of SALVAGE) by helping me out here...
what are possible things that could make ALL the
outputs of a microcore be HIGH at once, regardless of
how hard i try to introduce processes into it? i put
in a PIC (pulse introduction circuit) and pushed the
button a few (hundred) times, but all the outputs just
stayed high all the time. the only reason i can see
is maybe the 74HCT14 is static fried. I went over and
found i had attached a .22 uf capacitor to pin 14
instead of pin 13, so it wasnt working, but i switched
it and it still dont work. i checked EVERYTHING over
multiple times and it still is screwed up. whats
wrong with it? im gonna pick up a new chip tonight
and try it, but let me know what i can do to fix my
4nv microcore!!! (it is for my first 2 motor walker)
thx!

I DID say "no scalpels or lethal voltages", but the goal is still
survival. Here is a bit of philosophy for you. There seems to be a
conflict between Asimov's first law of robotics and Tilden's first law
of robotics.
Asimov: "A robot must not injure a human being, or, through
inaction, allow a human being to come to harm." (1)
Tilden: "A machine must protect its existence." (2)
However, consider the possible consequences in our society of turning
loose a robot capable of seriously injuring a human (or a pet) as a
means of self defense. There is a good chance that such a robot would be
dismantled or destroyed shortly after protecting itself, either by the
injured party, by law enforcement officers, or at the direction of the
courts. There's also a good chance that the builder/owner would suffer
legal and financial consequences.
Really, Asimov's first law is a subset of Tilden's first law, at least
in our present society.

Nope. Improve the chances of survival. Think of survival as long-term,
though. Sticking a 6 inch needle through Aunt Nellie's foot may save the
robot from getting crunched at the moment, but will probably not promote
long term survival :)
Your comment on "rules" leads me to wonder, is this a candidate for a
contest? Dare I even suggest one? Target completion date: June, 2001?
