Project Summary

The SIX AXIS ARTICULATED ROBOTIC ARM FOR INDUSTRIAL APPLICATIONS as a machine which replicates the movements of a human arm for laser cutting and drilling purpose and is based on six degrees of freedom for its movements. The complexities in cutting and drilling on a work piece are executed by a software used called MACH 3 on which we have to make G codes using JOG operation for the controls of the motors. By doing so we can accomplish major fine and accurate tasks in less time as it takes on a conventional method.

Project Objectives

Basic objective of our project is to excute professional and technical task with the finest precission and in shortest posible time.

Project Implementation Method

We are operating three of our stepper motors by using Mach 3 software which will generate G- codes by using jog operations. This codes will be send to the CNC breakout board which will give command to those three motors and the remaining two steppers motors and single servo motor will be operated through Arduino. All these combine motors will help us to accurately execute our program with finest precision. This loop will remain continue until we achieved our target.

Benefits of the Project

There are several benefits of our project like this robotic arm can be used in industries for laser cutting and drilling. It will save the time and money too. we only need one person operate this hand thus reducing labour cost too.

some of the basic applications are as follows: 

• It can be used to cut metals.
• It can perform laser marking and laser engraving.
• Laser cutting can be used in cutting packages.
• It is the best alternative to taxing task of manual drilling.

Technical Details of Final Deliverable

Controller control the motion of the robotic arm by means of drive signals.For cutting we are using 2500mw laser which can cut the at least 6mm cardboard sheet and for drilling we have designed our structure of 6mm aluminum sheet and for precision we are using stepper motor to get rid of play and give us the best possible result. It will work as a CNC machine

We have to design the articulated robotic arm following the degrees of movements of the individual limbs or the joints. The size of our robotic arm is 86.5 cm. If we look at the turning joints and their measurement individually they are as follows:-

1. The hip plate joint which has a thrust bearing for its rotation fixed beneath the centre of the base plate. The base plate bearing the load of the whole arm assembly is 18.5 x 18.5 cm. and its height is about 16.5cm. Its fixed on top of another Aluminum plate which which is 12mm thick. This plate is fixed on the main steel frame. There is a lineat  servo which is fixed to move the shoulder up and down which moves at 45 degrees of turn.
2. After the wrist X we have the wrist Y motor attached to the end effector and has a 180 degree turn which turns the end effectyor 180 degrees .
3. Then comes the wrist X join which has a stepper motor having a rotary motion able to turn the end effector 360 degrees.
4. Third comes the elbow joint which is made of 6 mm alluminum and  is 30 cm in length. It also has a stepper motor for its rotation and the degree of rotation is 100 degrees set for all our functional needs.
5. Second we have the shoulder joint which is 25 cm in length and has a 130 degree rotation from its end. It bears a stepper motor and its plate are made of 12mm alluminum for lesser weight.

All these movements comprise the six degree of freedom as in the movements.
