Subject: [alt-beam] Symet Question


So far from what i gather, the symet is a solar engine hooked to a cassette
motor with three 1000mu caps to balance that just jumbles around like a top.
am i correct in this description. is there any more of a way to make it more
interesting, sensors? steering? I have the circuitry for it and have the
general understanding, anybody ever build one before? any cool way of making
it move differently. I have an idea of hooking sensors up to an reverser
circut to make it spin the opposite way once it hits somthing, does anybody
happen to have a good small minimal reversing circuit that they know that
works well? i've got a tape motor n stuff, has anybody experimented with
different wheel types. I know that by know i've gotten very annoyingly
inquisitive, but any help is welcome, just wanna make the best darn symet
anybody's ever seen. (what can i say, perfectionism is nuisance). Thx for the
help so far! Keep on BEAMin'.

read the Feb 2000 issue of Smithsonian... The carticle is a very
interesting read! I like it, and I recomend everyone go out and read it!

I read the post by bruce... and it has inspired me!!! I saved it to a
text file infact! I've been familiar with the concepts brought up, but
not in electronic form! I'm going to try some of them out. I have an
"Enrichment Lab" for school, and I essentialy do labs based on what I
want to do. It's great! I can't wait to begin them! I havn't been doing
any robotics work lately, and I hope to finish up and start some new
robots, this time for credits at school!

In other news, I have a video capture card, and some "cinematic"
suprises will start popping up on my web page very soon! :)

I'm going to start with some small clips from the Algo's FACTory TV show
my robots were on. I have to compress one more and then update the page.

flash. If you look at MArk T's you really need metal ones. But, where would
one find these?

I found a nearly endless supply of 90 degree gearsets. 1/32 scale slot cars
use them for their drive trains. The largest gear reduction avaible is only
like 3:1. However, then can be installed directly onto a BG micro gear
motor, or modifyed to work with servos! Just pop out the metal bushing, and
glue it onto the servo output shaft.
