Xbox 360 parts?

I have the opportunity to have an old, maybe broken, xbox 360 pro from my brother. I 'm first going to see if I can fix it. But if I can't, I was wondering if there is anything I could use for a robot? I know there probably isn't, but hey what the heck. I thought I might ask. 


So I'm new to LMR, and this is my first robot. For now, it's just an Arduino Uno, a motor driver circuit, and two motors. The motor driver circuit I got from here: … Read more


Hi y'all, just joined LMR, fantastic site, lovin' it already . . .


I am a bit of a beginner to robotics, I mean I can program and all that, and make these things, but I know not how or why they work.

One thing I have been wondering is about capacitors:

When designing a circuit, how does one know where to place capacitors, or why to have them, or how they function in that position?

With this circuit in particular (from here: http://letsmakerobots.com/node/2074), why the caps?

those two in the top-right, why do they both need to be there?

PhD in Robotics

Dear Friend in LMR,

I m planing to study the PhD this year. I decided to Make my study about Robotics. I need  suggestions for good Universities, Super visors and Project proposals. any advices, comments or suggestions will be highly appreciated. the degree that i m looking for is PhD in Electronic and/or Communication Engineering. the detailed profession  could be Robot Building Programing...etc 


best regards



Ethical Bots?

I found this article to quite interesting, though I don't think we are quite there yet.



Good at designing robotics parts?

I saw this on Hackaday today, and immediately thought of you guys:


I've been asigned a project to make a learning site with Intellibrain Bot tutorials. I have to explain only software side of it and I know most of it. But I have never teached anyone anything and I have never been realy teached robotics, all the stuff I learned is from examples and asking people on internet for specific problems.

So my question is in what order should I make it? How to teach people who never used a PC to program robots in Java?

Hack your servo v 2.00 – Add 10-bit incremental / absolute encoder feedback to your hobby servo

Modified continuous-rotation servos are used extensively by roboticists due to their small form-factor, enclosed motor-gearbox, ease of mounting and high-availability. Some users keep the original drive electronics and the potentiometer feedback element but this approach allows for limited position control and velocity control / profiling. Others tend to remove them and use external control/drive boards and custom-made encoders. Ideally one would prefer to have the feedback element and the new drive electronics enclosed inside the servo.

London Robotics groups?


Is anyone on LMR from London? Is anyone familiar with any London Robotics meetup groups?

Does anyone attend dorkbot? I meant to attend my first dorkbotlondon this month, but missed it because of work! The next dorkbotlondon is in February.

I'd like to get involved.


Just some random thoughts

It's 5am and I'm still working on a project, not a robot or even bot related project *sigh*.  We all do what we have to do in order to clothe, feed and shelter ourselves and those we love if we they live with us.  This got me thinking of my bot Leo, and a few objectives I have for him such a new body for himas being able to 'feed' himself, and making a bot 'home' for him.

Robotics in movies....or at least in an upcoming movie

So this is related to the technology behind a new movie thats coming out. This was originally found on robots.net, a site I highly recommend checking out if you have never heard of it.

I was actually pretty impressed with what they had to show and how far along in the way of robotics we've already come.

In a way this movie reminds me of Ghost in the shell. 

I remembered that I was sweating for weeks about what should I have for a power supply circuit. However, I came accross this and all of my worries vanished. … Read more

courses in robotics and cs

Hey all,

I found this link this morning and figured I'd share it...it's pretty cool that they are offering these courses for free online!
