Transmiting Video/ serial data
May 13, 2009
Well after seeing Jim lovells updated bot i've decided i want my next project to go towards that direction. Sorry i still dont know how to link the post right but its here, http://letsmakerobots.com/node/6820. And starting either next year or in a few weeks ill be be the president and founder of our schools new robotics club : ), i think for the first meeting i would want to show a bot that would demonstrate a wide range of tech. My plans centered around a start here robot with maybe an added line follower routine, and appropriate sensors, and now hopefully a live video feed from a mini-cam/ data commands via wifi or bluetooth.
I glanced at frits tutorials on wireless for cheap, so i think i can have one wireless module on the robot itself, and maybe an 18x or something hooked up with another attached to my comp, that would take care of the movement controls, but im interested in something like what jim did and i want a video feed. He said he used a video trans/receiver pair, i was just wondering if this was connected to the picaxe (it would seem not) or if its just seperate.
Suppose i wanted to replace the rx and tx with a wifi or bluetooth module, i know they can get a little pricey but i want to put on a good show. Is it possible to interface the camera with the pic? the manuals didnt seem to mention it, and i dont know about converting video data to serial then back to video. For the final product i would like to have the pic communicated via wifi to another wifi device, say an ipod touch. I somewhat get the hosting part, but its the video im mainly concerned about.
Im looking to use the same camera (http://www.supercircuits.com/Security-Cameras/Board-Cameras/PC300XS) but i have absolutely no clue about the video transmitter and receiver. I suppose i could buy one of the cheap 40$ tuner cards they sell at best buy, but is there another cheaper way to transmit video wirelessly? With my PTA grant, im looking at a budget of around 100-150$ so it would be nice to find a way other than the tuner card. I've also checked out the qwerk bot which uses a webcam, im not sure if there a difference. It would be nice to have the cam and bot run off the same power supply.
Right now this is a really rough idea, just putting it out there to get your feedback.
