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

Hi, I have made this robot and I want to mess around with the code and stuff, I can make it walk forward and backwards but is there away I can make something that lets me switch between codes whilst moving around, so for instance im showing it at school and I want to show what it can do to its full potential?Thank you for reading and please try your best to provide me with an answer.

Hey, is there any reason why my version of this robot is walking to one side and then end up walking in a huge circle, does the original one walk straight?

No robot or car or anything in this world did ever drive straight.

Some robots turn more to the side than others.. and then you ajust them: Code or mechanics. Till they move straight enough :)

I think I have shown quite a bit of everything in the code named 'dead_duck_walking_and_tricks.bas' - I can only help you that far, you will have to code your own robot from thereon - and if you have not done it yourself, what is there to show? ;)

If you want a robot to do things based on inputs, finding it's way etc, I'd suggest you have a look at the top menu, 'Start Here'

hi please could you watch this video, i am making this robot and i have come across this, is this a problem or does it really matter, when the right servo is in the air, the middle one is flat against both of the servos, but when the left servo is in the air, the middle servo is diagonallly touching both the right and left servos, watch the video to understand, either comment on the video or back on here, thank you, here is the link: http://www.youtube.com/watch?v=MZg50gkjmBM

Hi, as you can read in the rules (and please, I have been writing to you a lot about this), never start a topic line with the word "Help". Thank you.

Great thing you made, and posted a video - makes it a lot easier to help you, awesome :)

You are posting your questions all over: On Youtube, Picaxe forum, and in various posts here. Please stop doing that, only ask on the project page, thanks. (Please do not ask people to answer on YouTube - if we start doing that, it will be very confusing for everybody)

OK.. to the question: The 2 small sticks has holes. These should be closer together, then the middle servo would not be that loose. But does it matter? Well, you find out - that is how we all do things: Try and error, test and try.


i dont understand, where is the project page, i thought this was the project page plus i dont understand whats wrong with asking for help?

Duane Degn makes all my points more clearn than I am capable of :)

This IS the project page - problem was that you asked more questions about your project around in various other posts as well. I had to log in as Webmaster and delete them. That took my time, and it took the time of everyone else who had been reading and commenting.

Time.. What does it matter? It matters a lot. We all want to build robots - our own robots. Of course we also want to help each other, that is what we ar here for.

Making robots is very time consuming. One has to test, try, test, try and test again.

If you are asking instead of testing and trying, you take away our time, and all in all we can make less robots because of the way you act. If you act that way.

I know you are very young, and you are doing a cool project, and we are all here to support you the best we can.

But you HAVE to read and understand the rules (top menu), and you have to first read if others have asked the same question, and if there is an answer.

This is why posts has to be collected on the same pages, and not scattered all around - so we can find things, so you can find things: Other peoples Q&A's.

TEST AND TRY ALL YOU CAN before asking for help. Only when really, really stuck, make a good description of your challenge (your video was a great way to show us the problem you had, many could learn from you there, great job!) - and post it on the page where you'd yourself find it most logic to seek for the answer.

When ever you post a QUESTION, make sure that the SUBJECT will tell the next person what this is about.

Why? Imagine you where searching for "Where to connect batteries to part XYZ", then you, yourself, would not be able to see that others had already asked that question and got an answer, if the subject was - as an example - "Problems with my robot".

It should be clear what the question is about, because then it will also be clear for the next person that there might be an answer in that post.

Basically: When you post on LMR, you litterally create LMR. There is no paid authors in here, everything _you_ post is authoring, You make LMR. Think about that every time: Am I making a better site this way? - That is basically what we are on about.

I hope it makes sense, and don't worry for us being harsh on you, I see that you are actually doing a fantastic project, and we all welcome you very much, because we know that someone like you can make amazing projects - and we are here to help you. Including helping you how to make a better LMR ;)

When you ask for help in multiple spots you're wasting people's time. You asked if the neck and battery pack were needed in the forum and I took time to answer you only to find out you've already received the answer several times. I didn't know you already had the answer so I wasted my time explaining things you already knew. This makes it much less likely I'll want to answer your next question (though apparently that didn't last long).

Also, I think Fritz was expressing some frustrations about having questions about a robot spread across the internet. The answers people have provided are not likely to help the next person who comes along with the same question. If all the questions about a robot are asked on the robot's project page, then the next person with the same question won't even have to ask it since the answer will already be available.

And while I (and others) are annoyed at you (which will pass), I'll also point out that us old fuddy duddies like letters which are supposed to be capitalized to be capitalized. These posts aren't text messages. "i" isn't a word. "I" is a word. We also like apostrophes (a lot). Did I mention posts aren't text messages?

For some reason Chrome doesn't underline misspelled words in these posts. I often (and I suggest you always) cut and paste posts to a word processor program to check the spelling before clicking the "Post comment" button. This will go a long way in reducing peoples' annoyance with your posts.

Hello I have read through the rules and I have learnt from my mistakes, hopefully everything in this reply is correct. I have tried adding the neck piece, the feet and the battery pack, when I have done so the robot still marches sid to side, I have uploaded a short clip of this to YouTube, please visit the follwing page and view the video, please post the reply in here, I would really like to finish this soon, here is the link: http://www.youtube.com/watch?v=5hyiiggDcCQ, sorry for my mistakes previously, it won't happen again. Thank you!
