udpRC is a radio control using your device's touch screen or gyros to control a car or a robot through Wifi. This apk is based on the proven user interface of the picCAR App. In concert with a receiver such as the PiKoder as outlined in http://www.pikoder.de/WLAN_RC_EN.html you would enjoy a control range of up to a few hundred meters and features such as fail safe function.
The app supports the standard R/C car configuration using one channel for steering and another channel for speed (ESC). A checkbox "Mixing activated" in the app prefs is employed to switch to a two motor mode used for e.g. tanks controlling speed and directing through two motors.
Please refer to the udpRC web page for more information and a comprehensive user's manual.
