Let's Make Robots!

Animatronic NIN

Uh, yeah. Nothing like taking a happy fun memory and turning it to Nine Inch Nails :

FYI, the Rockafire Explosion was an animatronic band that played in a kids pizza chain, Showbiz Pizza, in the 80s. Kooky, happy, family songs, played Beatles Happy Birthday song for kids, etc. Now only in collectors and inventors hands. 

And now, after the Showbiz's have closed, this.  Wonder if they'll cover Pantera?

SparkFun order compilation

Well i've been saving up for another sparkfun order for a while. At the moment i only have a 28x1 w/ project board, one l293d, two motors, a sharp and a ping. Today i recieved two GM2s with some wheels and two more L293D's but i dont have another chip to use them with. Point and case i need some help picking up new parts.

You as a sensor?

Quick question... I want to make sort of a "person switch". Two contacts, where each person would place one finger each on one of the contacts then when these two people would touch each other the circuit is completed. Now, I have not done any preliminary work on this at all --I havn't even measure-thingy'ed myself yet (I would assume we have to be talking some pretty major resistance here).

Beginner here. I need some direction...

I have come to a point in my life where I have some free time for a new hobby and I think robotics is something I could enjoy.

As I understand it, the following seems to be the basic skillset necessary to really get into robotics:

-  ability to understand and create mechanical features with your hands

-  have an understanding of electrical circuitry (especially in the context of commonly used robotics components)

-  have an understanding of event driven computer programming

Accurate temperature reading


Sorry if this post is in the wrong place but I don't know where it should really go?

Does anyone know if there is a piece of hardware that I can connect to an Arduino that will give me an accurate temperature reading. 

Are thermistorsaccurateenough to get a reading from?

Thanks in advance,


Looking for foam tires that you can mount to a servo

I have been looking around the internets for foam tires that are made to mount to a servo horn. Any links?

Motion Detector

As my ignorance is almost complete, I'm looking for some advice on a suitable sensor to use with a PicAxe for a motion detector. I want to be able to detect a moving person at a distance of up to 2 to 3 meters, over a wide angle. Any ideas welcome - especially zany/arty ones.

Remote control thing

I really dont know what the exact definition of a robot is...(Being autonomisnous*) but i am going to attempt to make a 4 wheeled remote control hybrid car with AA and solor panel on top...my goal is to be as fast as i can controlling it.

Items already planning on use http://letsmakerobots.com/node/5446 ... is it any good? and are there any items/stuff that can help me or intrest me on this project...thanks for your help and hope its not too stupid of a question

what will i need? i know a source/wheels... what else/what prodects?

LMR DAGU Contest - Ideas ... or ...

<tongue in cheek>

Just so that everyone gets a fair peek inside everyone else ideas file, I propose that all contenders in the LMR DAGU Contest post their ideas right here. Any conceptual or technical art work is encouraged. Schematics, photos, drawings, origami, whatever. Use this thread for inspiration and sharing!

After all, we are all going for the same goal, aren't we?!?!? Or are we....

<tongue out of cheek?>

My first robot help

Hello i am new here...is there a simple robot to make that is remote controlled and runs on AAA battery? or is there something to this i dont understand yet? 0_o

 Totally new ..know nothing and REALLY want to get into this if anybody is willing to teach me a step or two
