Use your Android phone or Tablet to control a robot via Bluetooth and drive it like an RC car. It controls the speed and direction of a two-motor-Robot car, and also allows rotating clockwise and counter-clockwise. The Robot Control app works like a joystick. You touch the screen and move your finger to run the robot. It uses a simple protocol of 4 bytes, one byte for each of the two motors(-127 to +127), and two bytes for packet identification. Checksum is built in and can be enabled for added safety. The Robot Control app has been tested extensively with a power robot (see youtube video below, size of a wheel chair) with Android 4.1.1 on both android phones and Tablets. It is compatible with Bluetooth modules (such as HC-05, HC-06, and HC-07 as well as other series). It has been used extensively with the microcontroller ATMEGA328 (Arduino compatible), and for which both the Arduino Sketch file (DroidBot4Arduino.ino) for Arduino lovers and the compiled .hex file for AVR C programmers are available. Fully compatible with ATMEGA328 based Arduino boards such as Arduino UNO and others. For more information, please visit

    So far I tried many Remote Control products for Arduino using Android Bluetooth, this is the best one I have come across. It is very easy to use with just one finger (Joystick) and gives total control of the robot. I happily recommend this for some one, looking for Android Arduino Bluetooth remote control for their projects.
