RC control via WiFi (and iPhone)

From MakeZine: "From the MAKE Forums:

If you've been looking for a way to control your robotic project over a WiFi, then you might want to take a look at the Remote Control Over IP (RCOIP) project by Mike McCauley. He uses a lot of complicated words, but it's basically a communication protocol to do RC-style control over an Internet connection.

Of course, you can't connect directly to a traditional RC device using your laptop, so you will need to substitute your radio receiver for an Arduino with a WiFi shield, and put the RCKit library on it. For the controller end, you could use another Arduino or a computer. He's also got a (nonfree) iPhone control app, which allows you to control your creation using a simulated touchscreen RC controller.

There are probably a bunch of different protocols that people use for this, such as Open Sound Controller- do you have a favorite?"

  • Its unfortunate that cheap wifi modules are hard to find. It seems more cost effective to use a full featured router (cough-linksys-cough) than to just use a wifi module for most cases. Prices gotta come down sometime tho.
  • WiFi Servo Controller with webserver.
  • I really wish there was an inexpensive device that bundled something like the wifi shield with a wireless webcam
  • Oh' that really great !
