Wireless Control of Pick and Place Robotic Arm Using an Android Application

The work is designed to develop a pick and place robotic arm vehicle with a softcatching gripperthat is designed to avoid extra pressure on the suspected object (Like Bombs) for safetyreasons. The robotic vehicle is android application controlled for remoteoperation. At the transmitting end using android application device, commands are sentto the receiver to control the movement of the robot either to move forward, backwardand left or right etc. At the receiving end four motors are interfaced to the microcontrollerwhere two of them are used for arm and gripper movement of the robot while the othertwo are for the body movement of the vehicle. The main advantage of this robot is its softcatching arm that is designed to avoid extra pressure on the suspected object for safetyreasons. The android application device transmitter acts as a remote control that hasthe advantage of adequate range, while the receiver end Bluetooth device is connectedto the microcontroller to drive DC motors via motor driver IC for necessary operation.Remote operation is achieved by any smart-phone/Tablet etc., with Android OS; upon aGUI (Graphical User Interface) based touch screen operation.
