Android Controlled Robotic Arm
Android Controlled Robotic Arm report
Abstract: The work is designed to develop a pick and place robotic arm vehicle with a soft catching gripper that is designed to avoid extra pressure on the suspected object (Like Bombs) for safety reasons. The robotic vehicle is android application controlled for remote operation. At the transmitting end using android application device, commands are sent to the receiver to control the movement of the robot either to move forward, backward and left or right etc. At the receiving end four motors are interfaced to the microcontroller where two of them are used for arm and gripper movement of the robot while the other two are for the body movement of the vehicle. The main advantage of this robot is its soft catching arm that isdesigned to avoid extra pressure on the suspected object for safety reasons. The android application device transmitter acts as a remote control that has the advantage of adequate range, while the receiver end Bluetooth device is connected to 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 a GUI (Graphical User Interface) based touch screen operation.The design analysis of a Remote Controlled “Pick and Place” Robotic vehicle has been presented in this paper. This work unravels the fact that man would always want to adhere to safety precautions at workplace and even in its environment, to be able to handle some specific tasks, like sending the robotic vehicle to hazardous environment to obtain samples for chemical analysis.The robotic arm has six degrees of freedom. It’s made of various links forming an open chain. The arrangement of these links depends on the adopted design. The arm has a rotating base that is resting on the upper region of the vehicle. The arm terminates with a gripper or a specialized tool holder; it has six degrees of freedom. The first three links of the arm form the body and which helps to place the tool holder at the desired position at a location insidethe workspace or environment. The remaining three links make up the wrist of the robotic arm and are used to define the orientation of the robotic arm end points. For the purpose of analysis, the robotic arm will made of joints, which will be named as wrist, elbow, shoulder, and base.
