Subject: [alt-beam] Re: BEAM: Tendency toward miniaturization
It seems as though the message i was sending across has been garbled.=
I
am not against using microprocessors, especially combined with beam. In =
fact
i think it will become neccesary. I was simply saying that Andy's goal o=
f
simply creating a robot to navigate through rugged enviroments without ha=
ving
the proper electronics knowledge was slightly ignorant. Robotics has its=
basis in electronics and to try to avoid having to learn at least some
electronics basics is going to bring you to a dead end.
I am completely in support of using BEAM in combination with
microprocessors, but to avoid learning some of the basic electronics is n=
ot
the way to go.

10528 Sun, 20 Feb 2000 17:25:54 EST [alt-beam] Breadboarded solenoids beam@sgiblab.sgi.com BUDSCOTT@aol.com well, i breadboarded (or protoboarded, whatever) the solenoid photovore that
i've been working on. now i swear i saw the solenoids triggier once, but then
i couldn't get them to trigger. i've got the circuit all hooked up correctly
as well as the solenoids. i've got two 4700uF caps hooked in parrallel, 1381L
(3.0-3.3v), and a large 5.5v solar panel, but the piece of #$%& still won't
work! i realize that transistors limit the current somewhat from the current
going to the base, but i still think that it would trigger the #$%&
solenoids. Patients is a virtue, or an asset, i cant remember which, any
insight? Thanks o ton for help!
