Remote Control transmitter for RCOIP (Remote Control Over IP) protocol. This transmitter works across an internet with the Arduino RCKit, a kit of software objects for creating Remote-Control vehicles with motors, steppers, servos, analog and digital inputs and outputs. Includes telemetry backchannel data to display signal strength and battery voltage at the remote vehicle. Uses a Wi-Fi Ad-Hoc network and the RCOIP protocol to communicate with an Arduino equipped with a WiShield and your custom vehicle software written using the RCKit. RCKit and the RCOIP protocol is available under GPL or Commercial licenses. See http://www.airspayce.com/mikem/arduino/RCKit for more details Videos at http://www.youtube.com/watch?v=SKwY-CcotRY http://www.youtube.com/watch?v=i0ZogFmytPI Forthcoming releases of RCTx will include configurable transmitter interface, backchannels for GPS positions, remote vehicle position mapping, remote vehicle webcams, macro recording and more. Note: this transmitter cannot be used to control conventional radio control vehicles. The vehicle must be equipped with Arduino, Wi-Fi and the RCKit software.
