Hello everyone!!!!


Ya this guy is mine :D Not that bad na ??




Taugh wall-e prototype to draw Rangoli.

Check video in youtube for more description.


Taught it to write, here it writes LMR

Really an amateur but nevertheless it is satisfactory :)



The neck does not rotate because we got a continuos rotation servo in our kit so its used to keep turning and turning trying to suicide. So we had to make our own program to make it turn etc etc.

I'm trying to make this as short as possible because this will be more of a discussion than me talking only about my robot.

I have just startedmaking robots actually with help of LMR and my friends. This is my first successful one...I know I know this is what I have just copied from http://letsmakerobots.com/start ofcourse this is true, this is where you all must have started your robot venture (thanks a lot fritsl!!! :P ).

Anyway coming to the point me and my friend have decided to take the whole of May to make new and better robots (now that we know the basics..well almost ).

I know many of you have done this exact robot. I really wish to know what all new things did you try on the same robot using the same picaxe board, for example putting some LED or buzzers as fristl stated.

We are going to try making "legs" for the little guy, for this I will really need some help and assisstance from you all.

Reply in your ideas, how you have meddled with your robot.. dont feel shy to post pics of your robot.

You can post even the unique program that you wrote just to share so that others can get more ideas. :D


 (this guy is wat i want to make! help me !!)

Lets go make the future even more WOW!!!! :D :P

Just comment you robot enthusiast :P

Asimo is a very high-tec sophisticated robot that is 4 ft. I take it you are making a small version with less sensors. I would not suggest creating a bi-ped until later on. Id start with a quad legged robot. Hint: think of a steam trains front whell assembly.

ASIMO is the current most advanced humanoid ever built...right now I definitely cant even make even its hands...but soon enuf mayb v can make something even better

You can make a simple chassis with CDs, like this one: http://letsmakerobots.com/node/22467

Add 4 servos and you can make a biped: http://letsmakerobots.com/node/23871

Arduino version: http://letsmakerobots.com/node/23022

And (one that was not built by me) with 3 servos you can make something like this: http://letsmakerobots.com/node/24138


wow now tats awsm man!!! i really have to understand how to use mmore than 1 servo and sensor

thanks a lot

just attached the program

will some1 tell me how to you use random function to make the robot turn either left or right but not the same thing again and again

Added a new video of the updated version with a new chassis, 2 LEDs and a whole new code!!

First of great job with the second robot =). You wrote that you and your friends bought a continues servo, and in your program you took out the part to turn the servo. This is occuring because your servo had 360 degress of rotation, while you only need 180 degress for the sensor. In your code you can adjuct it, so that the servo only turns 180 degress, not 360. 

Firstly thanks a lot. I tried everything possible with the coding of the servo but it went in vain. The servo just would not stop rotating(because it was in a loop statement) so it was not possible to control it.

It's not a 360 servo he has. It is a continuous rotation servo (intended as a drive actuator). So there's no easy way to make it go only 180.

There are servos that turn 360 and then stop. If he had one of those he could either gear it down or control it via software.

Out of curiosity, DTB, did you get that servo accidently as part of the start here package? If so, they sent you the wrong part and should replace it. If you bought it separately yourself, you are on your own.

Actually IG they said they did not have the standard servo so I asked them whether they had anything similar to it. The showed the servo which I currently have, I never knew all servos are NOT the same so told them OKAY.

Hence I ended up with this :(.
