How do you program a screen with Arduino?

How do you program a tv screen? I want to do it with arduino, so I can put it on one of my current robots, an entertaining stationary robot head on my desk. I provided some pics of the screen I'm using. Please comment.


Cheap CCD or CMOS camera with external sync.


I am doing and experiement where I need 2 camera but the capability of handling an external Sunc signam.
Most of the units I have seen are either too large or too expensive. A single board unit would be perfect.



Testing the wheeled version

As announced in our previous post, we are working on wheeled version of our robot. Tires and shaft adapters are arrived today and we mount them to conduct first test drive. Here are some photos:

Here's a cool robot video:

Taking Video From a Webcam in OpenCV

So I have been trying to get OpenCV to work. I displayed some pictures in windows and simple stuff like that. Then, following along in my book, I attempted to write a program which would take video from a webcam and place it in a video. Here is my code:


#include "stdafx.h"

#include "cv.h"

#include "highgui.h"



main( int argc, char** argv ){

cvNamedWindow( "Webcam", CV_WINDOW_AUTOSIZE );


CvCapture* capture;


Videos for LMRv4 Fundraising


Make Some Videos!

I'm encouraging people to record a 30 second or less video at home and send me the file, or link on YouTube or other hosting site. Doug and I will compile a video of LMR members explaining why LMR is so important to us, and asking for support. If we show the world how much we care about LMR, and what this community has done for us, they'll care too. Maybe enough to contribute a few bucks.

I've linked the videos I've received so far at the bottom of this post.

Camera that can do everything - call for suggestions

I need your suggestions and recommendations.

What if I were to buy a fancy camera for a robot? I want it to be able to do pretty much everything. And still fit on my robot.

Let's see first what "everything" means. This list can grow as you make suggestions in the comments.

Ardunio - The Documentary

That you guys might like this....   :)

This is a great one to watch running at about 28 minutes, very impressive and a great story behind what we find in so many of our robots today.

DarwinBot now in Soccer mode

My DarwinBot has been reincarnated into erhhmmm something completely else.

As it is right now (if it is indeed live at all) you get to control it. It is very very simple. Just five little commands. To get control, you must use the magic word first: control (and hit send). Now you have a limited amount of time to control the bot.

The available commands are:

Multipurpose manually controlled platform with wireless video.

Incredible wooden mechanical machines video

Have a look at the engineering that has gone into some of these machines. I especially like the gearbox mechanism on the 2nd video to change from raising to extending the arm.

Some questions from a beginner.

Hi Everyone,

First, thanks for taking the time to read the forum and answer questions from new guys. I know it's sometimes a pretty thankless task, despite being very time consuming!

 The site looks like an excellent resource, and when I have the time I shall read it more thoroughly. In the meantime I have some quite simple questions about a robot that I'd like to build.

Entry For Oddbots Robot Video Competition

Hi all, it's 2:44 am (yawn), and here is my video.


I spent ages trying to work out the music for it only to find out just before uploading it

that Youtube will probably mute it :(


Oh well. if it happens i'll try another service.

anyway do enjoy.

I can't handle the stupid alone, so I decided to share.

Video editing issues

So a lot of people want to use the lmr watermark on their videos, but how do we do it?

Please comment what programs you use to edit your videos, and I will use my connections toget information on each one. Maybe we can get a little FAQ going on this guys!

I think there is something that Rik isn't telling us...

Do you secretly have long hair and like to wail on keyboards???

I wish I found this when you posted the previous "pulse"

Live video streaming for remotely operated robots, solutions?


I recently tried a small videocamera like this one, and i must say that, despite the low quality, they do a decent job, except when heavily shaked.

Now, the main problem is that they have a limited range, and that they have a radio signal on their own, separated from the main robot control. This means that you cannot make a program that behave based on the images, and that the two radio signals can have different ranges.

LMR scrapbook

Hey guys,

More and more often our work is showcased on other sites - let's have it collected, links, scrapbook :)

We all know that a robot is supposed to move. Without movement, a robot is just dull. The same goes for pictures of robots. We wanna see them move! Here are a few … Read more

Amazing homebuilt quadruped

Before I start making and sharing videos: Which video service would you recommend?

Video transmission

Hi everyone,

I'm quite new in all of this, but i want to build a robot able to transmit video, and possibly sound. I've got a common webcam and I want to make it wire less, but I don't know how to do it.

I would apreciate any help from you lot.
