In this recent time, android device as a user and as developer is become more popular. So we have selected android based device which have Google voice command and developed an application to control the robot to get a desirable output. We can communicate with the robot from the android device by a Bluetooth module which is connected to an arduino installed in the robot. This robot is also can detect obstacle and avoidance using sonar. It transmits phonetic pulses in its surroundings and for the echoes from the objects nearby that lie within its working range, hence detects obstacles. The robot is installed with Omni wheel which is a special function of this robot. This Omni wheel that provides easy 360° movement propel with rotational and sideways maneuverability. The outcome of the project is a combination of embedded computing and programming.39 pagesenBRAC University Internship reports are protected by copyright.
