Thank you for the interest, Gerald.
I have uploaded a circuit diagram, and will be working on explaining
what's what there
BTW, I did the drawing on an XO 1, using Inkscape in Gnome. Slower than
the quad core, but works!

let's ask Jerry (no pun: his website is http://askjerry.info) for the
frame design - he has also a nifty tractor body design there.
Hey Jerry! do you have handy the blueprint of the tricycle that we may
share it with the friends here?
Thanks!

Yama,
This is really great. And thanks for updating the wiki (sorry about
the cold, though).
Can you provide specifics on the hardware/frame for the robot?
Thanks.
Gerald

So far mspdebug Linux tools "work" in OLPC's XO computer using the
directions in
http://processors.wiki.ti.com/index.php/OLPC_XO-1 (major overhaul
today, courtesy of a cold/flu)
1) I beg mspdebug people to vet excessive heresies this noob might
have introduced in the How-To in that page.
So far I am managing without -mcu - or -gdb.
I actually have no idea what those are for, or if their
unavailability explains my so far failure to UART, or if we should
care... (for many things, it ain't broken...)
2) Fedora packaging people: any way to package
mspdebug msp430-libc msp430-binutils msp430-gcc msp430mcu
msp430-gdb ?
What gets downloaded through yum channels in the XO is very, very
outdated, and conflicts (cf. mcu and libc).
Please feel free to forward, as I have no access to "real" Fedora
people - don't even know where to look for them without making a
nuisance of myself and undue noise, and certainly do not know who
could maybe make a "package"(?) usable for the XO. Will this be
fixable for the next OLPC OS?
Daniel?
3) Robotics, Science, Sensors OLPC, IAEP people, please, if you
could test the GCC toolchain?
You do not need to have a Launchpad on hand. I am trying to catch
bugs and usability issues. Are the instructions clear? as much as
possible figuring out snags so it's easier for kids and normal people.

The brains of this "bouncy" are an MSP430 microcontroller (a lowly
g2152) controlling a L293 dual H bridge, senses two switches. Its
brawn a couple geared DC motors on 9V PWM in an askjerry tricycle
frame. Not counting shipping, less than USD $10 total. Coded in an
XO-1 all the way. Enormous thanks to the mspgcc folks that helped
me figure things like how to use more than one switch...
