IR DETECTOR

Ok

So i have a IR detector and it is hooked up to an arduino i have programed it with the help of this blog http://www.arcfn.com/2009/08/multi-protocol-infrared-remote-library.html i am doing the example that is named " How to recieve" 

Problem: whenever i click a button on my remote the number 0 apeers on the serial monitor. What does that mean?

It goes around just like an RC car but it's much more fun because it's floating.
Using a
Here's another project that I have, it was a physics project for school but I thought I could put an Arduino somewhere in there and make it more interesting, and it … Read more

Coaxial helis

I sorta got into "flying" robots recently and I have found answers concerning most of my questions, but there is a particular thing I don't understand about helicopters; how do the coaxial system work (I mean, how can I make one from scratch). I understand that each rotor cancels the other's torque, but how does all this mechanicaly work? Are the rotors dependant on each other for speed (I suppose that's not true because the heli turns probably by increasing torque generated by one rotor and decreasing torque on the other).

My UAV ideas

I've been reading this site for the past week or so, and it has really inspired me to get more into robotics. I've had a couple of ideas for robots that I want to make in the future, I am going to start of with fritsl's starting robot, but I just wanted to share some of my future ideas to see what you guys think.

It flies, it flies!!

I posted some time ago that some friends and I were building a Semi-Autonomous Quad-rotor helicopter for our Masters' Project at uni. Well, we've been working hard, and have finally built the actual helicopter (using a kit found at http://www.mikrokopter.de ). After most people had left uni last night, we found a large open space to do some simple test flights. I would say that the flights were a partial success, in that we now have to calibrate all the controls and work out exactly what each control is doing (I crashed the helicopter on its second flight!)

Semi-autonomous Quad-rotor Helicopter

Some of you may remember me posting a robot page last week about this subject. It was decided (and I agreed with it) by Fritsl to remove it from there as it was no more than idea at the moment. That said, it was a very firm idea as this makes up a third of this ears mark and a sixth of our final Master's classifications!
