For the sake of it, I wanted to see if I could make a really simple biped - and this is what I came up with :)

I thought it was really fun to do, much more than expected, I can recommend it :) if I can find the time, I would love to do some other versions of this kind of simple moving creatures.. a couple of servos, wood, glue, Picaxe, back to basics, good fun :D

I really liked this 'bot, so I cloned it, but based on AVR/Arduino since that is what I have and know.

I posted a short video at



Thanks for sharing your design, and all the other inspiration on these pages.  I am new to robots - this is my first build.


That's a really nice job! Well done, I hope you'll post it as a robot here on LMR, and also include your code. It looks like a very nice Arduino port of my PICAXE basic, I think know that a lot of people are asking to see that :)


Thanks.  I posted it as a robot at


this chip is so far not popular in China.

also from youku, haha~

still wondering what servo he used.

this is truly wonderful work.  thanks for sharing. 

Dont know if you've seen it, but this bot is shown on the picaxe website on the video tab of the AXE320 module page (http://www.picaxe.com/Hardware/PICAXE-Chips/PICAXE-08M2-Module/)

BTW: you did it again. You've created a robot that moves in a very cool and unexpected way. You the master of moves

Thanks, Yes I saw it :) Clive from PICAXE wrote me a cryptic mail that he had "put up some random video he found on Youtube there" ;)

Hello, i am a beginner and i cant get picaxe or adruino in my country , so what should i do about the microcontroller and all other basic stuffs.Will anything related to computer parts do the job , please suggest me what should i do.

You should look at the top menu, where it says "Start here".

Regarding getting parts: I live in Denmark, and to the best o my knowledge I cannot bou the parts in my country either. That is why we go to webshops - in this cae, as shown in the video, go to picaxe.com - That is what we do, and then the parts come with the mail.
