Robotic Arm Using Arduino Uno

Abstract

The applications & advantages of remote 
controlled robots are plenty, especially in specific 
areas where people cannot go there to perform 
specific tasks, these robots are playing a major 
role. The system designed here can be used for 
picking any small object from the hazardous place. 
The technology implemented in the system offers 
many latest expectations. The advancement of 
technology has made possible the implementation 
of embedded systems in each and every field. This 
project presents a possible solution whereby the 
user controls the robot for picking and placing the 
goods by a mobile phone through its android 
interface. This results in a simple, cost effective 
and flexible system, making it an excellent feature 
for future smart robotic operations. 
To prove the concept practically a prototype 
module is constructed with electro-mechanical 
equipment that is guided by android device and 
electronic programming. Many robots have been 
built for manufacturing purposes and can be found 
in factories around the world. Here we are 
developing the remote buttons in the android app 
by which we can control the robot motion with 
them 
in 
which we use Bluetooth/WiFi 
communication to interface the controller and 
android. Controller can be interfaced to the 
Bluetooth/WiFi module through the UART protocol. According to commands received from 
android mobile, the robot motion can be 
controlled. The pick and place robot (robotic arm) 
designed with a microcontroller unit, functions 
according to the command signals generated and transmitted from the android device. Based on this 
information the robot will be moved in all 
directions. This robot is equipped with a gripper 
mechanism at its front side for picking the object 
and after holding the object it will be lifted up to a 
certain height and then can be carried to the 
required place. DC servo motors are used to 
control robotic arm including functions like 
controlling the gripper mechanism is performed. 
The robotic arm designed here has four degrees of 
freedom just like a human hand (shoulder, elbow 
and fingers as gripper).
