Let's Make Robots!

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.

Thanks.

Flying bots

I'm working on making my own Robot controlled helicopter. Is there anyway to calcute the wing length of the blade in order to lift the helicopter?

A simple HTTP communication protocol between wifi and Arduino

How to let the sensed data (e.g., temperature) on the Arduino send to the remote server? 

The following code is used to realize this function.

void setup()

{

 Serial.begin(115200);

}

void loop()

{

   int n=analogRead(A0);

   float vol=n*(5.0/1023*100);

   upload_sensor(vol);

   delay(5000);

}

 

void upload_sensor(float vol) 

     // send the HTTP PUT request: 

     char buf[200];

Motor Arm Length Calculator

Below is a picture of what I'm trying to build. This is the motor that I'm using, which has plenty of torque.


Circuit board 90% complete

So this is the first pic when it was about 50% complete, with the picaxe adapter mounted. The jumpers next to the adapter are used to select which picaxe to use when programming.

The next image is with the pwm circuit that I had worked on, mounted on the main circuit board.

The 08m(empty socket at bottom right) controls the motor pwm control circuit.

The 14m(top center) sends signals to the motor pwm control circuit.

I wish I had enough time to hack my graduation hat like this

I was looking a while back for people that had hacked their graduation cap. I didn't find any links as to how to do it, but one professor actually designed a circuit board to replace the cardboard with some ultra-bright LEDs.

angered his fellow professors something fierce, but everyone else loved it.
