9191 Fri, 14 Jan 2000 12:00:26 -0500 [alt-beam] Re: BEAM LEGO was microcore experimentation kit beam@sgiblab.sgi.com "Sathe Dilip" Wow, a message from 10 years into the future :-)
------------------------------------------------

To begin with let me say that I haven't played with lego blocks in
years. After reading the messages so far, I have some thoughts &
questions. The questions below are kind of loud (written?) thinking &
not in response to any particular message.

1) The blocks may prove useful as a learning system and as a
breadboarding system to tryout different ideas & configurations but,

will the additional weight per block not make it difficult for the bot
to move efficiently? OR again the idea here is to be able to build it
just to see/show that it works?

2) Is there a mechanism that will allow experimenting with say the angle
between the front & the back motors (are small increments in angle
possible with standard blocks?)

3) Will it be possible to build a bot entirely with the pieces
provided? e.g., will there be different leg shapes readily attachable
to the gearmotors?

4) Does the plug-in type construction provide enough integrity to the
body of say a walker that the parts won't come loose when the legs start
pulling against inertia/obstacles (& at an angle too as in question 2
above).


Thanks

Dilip

(In case you didn't get the ref. to 10 years in future - look at the
date on the previous message in thread)

I know we need bias points. Hence the quote "With the solder pads you would
be able to have jumpers to sensors, and motors drivers, etc." from my last
post. :) Thats what those little blue things represent in my drawing,
plugins or pinouts for biasing the circuit. The red dot is an LED. The
drawing was done in haste...I had homework to do...but needed to get that
idea on "paper" before I forgot it. Depending on the way the pins are bent
though...you can easily make a three dimensional circuit. They kinda take
on the shape of Mark T's hexes...but they use plug ins instead of solder.

CYA,
Dane
