Automatic Robotic Arm Based on Bluetooth Regulated for Progressed Surgical Task

摘要

The aim and objective of its purpose is to design a prototype that allows an android device to control a robotic arm through Bluetooth for surgical operations more accurately. The developed prototypes include two servo motor driven by the motor driver to place the object after picking it up certain distance, also for rotating robot arm in the desired direction. The movement of the robotic arm was controlled by programming the ATMEL microcontroller. The robotic arm has a grip that extends to 6cm and shuts to 1.5cm, can pick up and drop the object up to 350gm. Bluetooth module is used to wireless communication between the mobile application and the robot. The Stabilized output is achieved using IC L293D. Polymer material was used to build the bot arm structure, the “total weight” is reduced without affecting any parameter. To bring down the cost of whole prototype without comprising on efficiency the number of DC motors are reduced to two instead of traditional 4 motors setup. Hence the developed system is more flexible and the prototype can assist physicians during surgical procedures by picking and placing the surgical equipment, lowering the risk of contamination and human touch.
