The app running on an android device collects information from the onboard sensors accelerometer sensor or the touchscreen and gives sensor data over the bluetooth interface to the robot. The Robot controller -M1 which has a bluetooth interface is connected with a bluetooth UART module which is paired with the android powered device. The program running on the Robot Controller -M1 decodes the data and then drives the motors as per the gesture. The speed of the robot is also controlled by the angle of tilt in case of accelerometer control and swipe gesture in case of D pad control.
