okay folks,
i fell in love with the TYDM from fritsl, the version II ist so amazing, i simply wanted to build one myself. so i started wit the tutorial (thanks fritsl, your tutorials and tricks are really helpful!). only problem: it's not very easy to get the right parts here in germany, so i ordered some stuff in the uk (which was delivered VERY fast), some stuff at solarbotics (est. end of july :) and some other parts from italy. but i didn't want to wait for the delivery, so i went shopping and bought the 'essential' parts from a local dealer.there was no geared motor, so i bought two 'vario' transmissions that can be adjusted. and some really big wheels (the biggest i found!). and then i started. everything is mounted on a fat paperboard. the balance is not optimal bu it'll do for now. the next days i'll mount some led's and maybe an old speaker if i find one. maybe i'll visit my parents on weekend and will have a look ath the big LEGO-box, that stuff could be quite useful...

shopping list
thanks for the positive response :)
so, here is the shopping list:
the picaxe 28x1, motor driver, SRF005 were from techsupplies.co.uk
the other stuff is from a local store of conrad.de
conrad is available in other countries too:
http://www1.conrad.de/international/index_en.php
i used:
2 x 240788 - vario transmission with motor - 7,10 € each
1 x 227804 - 1:10 Buggy Wheels (2 in set) - 9,95 €
1 x 230500 - top-line mini-servo es-05 jr - 4,95 €
you can use the the article code, it's identical for every country
for this robot i set the transmission to 125:1, but the motors don't run at the same speed, and freddy alpha moves in slight corners instead of straight ahead...
the battery box has two holes in it which i used to fix it at the transmission boxes with som screws, so i can't place it freely and have to live with the bumpy balance point for now, but enhancements are still in progress :)

Cool
Nice robot, I like it :)
If you place the battery holder it little more to the back of the robot, the balance will be better.

Wow, an android on steroids!
Wow, an android on steroids! Can we please have a link for the gears and motor and tyres?
I think you will get a serious laugh if you add another battery - I am already amazed over the power you get out of 3 volts! ( 3 * 1.5 = 4.5 then motor driver takes 1.5 = 3)

Fricken Awesome!Balance not
Fricken Awesome!
Balance not optimal? Bah ! - The run and shake definately add to the character. Very impressed. Unique use of network ties too.
The gear box looks like it worked out nicely for you - do you have a link? Great Project!
