[IAEP] [support-gang] Robot runs on MSP430 + OLPC XO - QA and updated bundle request

[Yama Ploskonka]

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!
