Subject: [alt-beam] Re: Spyder VII
Yeah, you're right about that, however, if the robot is tiny, the space
savings could be realy useful. I may decide to use a plug in module and
make boards that can switch out??? Just thought I'd do something diferent.
Also, how much will a simgle leg motor running hard effect an Nv through
a 6 transistor H-Bridge? Anyone have ideas for enhanced feedback through
the H-Bridges, and I think I know how to make it turn in the fashion you
are speaking of. I was actualy going to have a head mounted on top, and
have it on a timer. MUXs would switch the H-Bridges to a non looped
sequence that'd raise the body to it's maximum height. It'd look for
light for a moment, and then continue. The position of the head after
seeking light would determine the direction it walks. I wanted to just
make it walk first though! Hehe! (:
