I saw your work over at the www.gumstix.org so I knew you were
involved. I have also seen some of your other projects so I wasn't
I will visit the sourceforge list and see what I can find. The
command line utilities are of little interest but, of course, the
source could be helpful.
As to Robostix, I almost ordered one Saturday, as soon as I saw it.
Then I decided to wait for a real, live project with motors/servos
and sensors interacting with a physical environment and utilizing
the gumstix in some capacity. I'm not in a hurry, there are a lot
of other things to work on.
I would like to work on a MicroMouse maze solving bot. I already
have the flood-fill algorithm running on the gumstix as well as on
an ATmega128 (7 mS solution). With the speed of the gumstix, each
iteration could take just a few hundred microseconds; about the time
it takes the bot to move 0.06" at 3m/s.
I don't really have very much experience with Linux. It isn't my
favorite OS even though I have two machines with Fedora Core 3.
Perhaps by the time I get the maze bot working I will develop an
appreciation for it. Or not...
Meanwhile, off to sourceforge...
Thanks for the tip!
