LMR Primer - Useful Links for New Members and Old Alike

"How do I build a robot?" 

"Which processor should I use?"

"Can you teach me to do that?"

These are the sort of questions we get again and again on LMR.  We're a helpful bunch of people, and we want you to have fun and learn too.  You are a very talented person.

The links I've collected below are ones that I feel may help you find what you are looking for. There are tons of other great material on LMR. Don't limit youself to the list below, but do check them out if you have questions in those areas.

DAGU parts price list for LMR members only

I have now removed the pricelist as we now have distributors in Europe and America.

European customers can buy from: Arexx Engineering or Conrad.

American customers can now buy from Robot Shop.

BETA of Next generation "Start Here Robot"

Update:

You can buy the parts now! (look below for details, will be updated as we arrange more kits)

Hi guys,

Sell your robot design

Hi Guys,

Consider this an initial test, and if it works out well, we will get more organized and set things in a system. But for now..:

If you have a robot that you think would make a great gadget as a finished product, you now have the option of selling this design to our friends at Seed Studio.

They will eventually need this:
A finished and working prototype, Gerber files, Eagle files, and Bill of Materials.

But first they need to approve the product.

So the way you move ahead is as follows:

Re-inventing the robot wheel

Anyone wanting to play with articulated robotic systems like arms, legs, pan tilt cameras etc will invariably end up using the ubiquitous hobby servo, a handy little gear motor that comes with its own angle sensor and closed loop position control. You just plug them in, send a position pulse and away you go. You can even hack them to produce continuous rotation for wheeled platforms, albeit without any closed loop control.

Multiple swithces to analog input?

Just had an idea. I'm planning to use a LOT of (tactile) switches on a walking robot. For instance I wanna put several under each foot. But it seems like a waste of pins to use a digital pin for each switch (or use multiplexers). So I thought I might be able to connect the switches in paralel and read several at a time from an analog input using resistors of different sizes connected in serial with each switch. Like this:

Live soccer robots on LMR

Recently Gareth suggested to me that it would be good to have 2 teams of my bi-ped robots playing soccer. This was too good an idea to ignore.

After talking about this idea backstage this is where we are at:

Miniature servo magnetic clutches

Miniature servos are great for robotics, they are small and cheap. Unfortunately they have very small plastic gears that strip easily so they always need replacing....  or do they?  Not any more!!!

very cheap GPS

I posted this as a comment on the cheap FTDI cable idea and it occurs to me that a lot of folks who might be interested will miss it there...

If you want to build a multicopter..

If I was building my first multicopter today, this would be my project.

Text from YouTube:

Cheap PCB batch house

Update 05.04.11: Seeedstudio now cheaper with more options!

Arduino Hand

I stumbled into this on the Internet :-

A simple elegant Hand sensor - servo finger combination.

EDIT :- YES I AM SHOUTING ......PLEASE NOTE THIS IS NOT ONE OF MY PROJECT

(however sponsor me the bits and i will make an LMR one)

Other robot builder communities

When we started this LMR-thing, there where not really that many robot-builder communities. Now I see them pop up, I just discovered the one that I will post below as a comment to this.

Apparently LMR is still the worlds biggest of it's kind, according to different websites that compare traffic, google-ranking etc.

So, I think it is in place to spread a little of our love, get the other guys some visits!

IR Homing Beacon?

I'm looking to build an Beacon, IR or otherwise, that a robot can see and simply drive to. Pretty much like a docking station for the robot to be recharged or a robot that follows you. (unless that's something different...)

I did a few searches, but I've only come up with robots that use a beacon and not how to build the circuit and write the code.

Any help? 

 


Edit: 8.31.09

 

I don't know if this helps, but I'm pretty much looking to build what CtC did here: http://letsmakerobots.com/node/6499
