Need Help!

Let's assume I have a robot in a room with a camera on it. I need the video source to be available live on a website. I don't want any latency at all (assuming that I have a good internet connection). Also if a user presses any keys while on the website, the robot needs to detect it and do actions accordingly. Now, I can handle all the actions the robot needs to do once I get the keys. There's a raspberry pi on the robot.

What would be the easiest way where we could achieve a bi-directional communication (one direction being video and another being plain text) between a browser and my robot, keeping the communication as fast as possible.

PS: I tried initiating a Google hangout and embedding the video, but there's a latency of atleast 1 minute.

    Can raspberry pi handle websockets? I've heard thats a pretty good way to communicate server/client. I haven't used them, but it might be something to look into. – Class Aug 18 '13 at 06:59

Simple to do. get the camera for Raspberry Pi from here.

You could use Motion JPEG for transmitting the video. Follow the instructions below.

Once you the the IP of your video stream, you could display it in a website.

To send commands to rap pi, whats the complication ? If your Rasp. pi have an internet (it should be for the video stream), you could write a program to read commands from your browser.
