Project Summary

Traditional CNC machines, are stationary and have boundaries for the work area, higher cost and portability issue associated with them.

Our Project is an Innovative transformation of a mobile robot to the portable CNC. The aim of our project is to overcome some of the limitations of the traditional CNC machines, as there will be no restriction for the size of the work area. It will also be portable and easy to use. This Project will also allow us to create what we want and where we want because Portable CNC Holonomic Robot (PCHR) will be able to move freely on any material because of omnidirectional wheels.

The design will allows the robot to be place anywhere on work surface and let it start doing the job. Because of it's portability and light weight, can be stored just about anywhere making it ideal for smaller workshops.

Project Objectives

The basic objective of this project is to innovate the CNC industry in Pakistan. The new design is portable and light weight which can replace bulky conventional CNC and also provide lower running cost and unlimited work area, It also frees up space occupied by traditional CNC machines.The traditional CNC machines are bulky and provide limited work area, where as Portable CNC Holonomic Robot (PCHR) is lighter in weight, provide unlimited work space and also portability. Worker has to carry material to the present bulky CNC , this means that the work-flow is slow and discontinuous, where as Portable CNC Holonomic Robot can be carried to the workplace easily. Our project aims to solve the problems of portability, limited work area, Higher Operating cost as well as Higher buying cost. Moreover, our system is a greener option compared to the bulky CNC machines that are currently being used.

Project Implementation Method

Firstly, the robot chassis will be built, supporting three stepper motors and omni wheels for holonomic motion. Proper calculations will be done for the robot motion in specified direction. Stepper motor driver will also be installed  to drive the stepper motor. Steps per mm calculation will be done for the scaled motion of the robot. The motors will be selected based on the amount of working load experienced by movements in various direction, along with the specific motor driver capable of properly driving the motors at their rated currents.

For controlling the system, Arduino UNO board with multiple input-output pins will be used.

The system will be equipped with laser having 20W. The x-y displacement of the platform will be measured through sensor in order to give feedback to the motors and provide precise control.

Benefits of the Project

Its intelligent design solves many of the work area, cost and portability problems associated with traditional CNC machines. Our product wants to help humanity, not harm it. The robot is basically a free-rolling CNC machine that can crawl over a surface. Weighing almost only 2kg, PCHR can be stored just about anywhere making it ideal for smaller workshops. It can be used both commercially and locally, as it is precise and also user friendly.

Technical Details of Final Deliverable

We are going to design a unique flexible and portable Omni Wheel holonomic robot. Since our CNC is based on a holonomic design the robot can freely move in any direction .The robot has an on-board interpreter that recognizes the g-code output from any G-code generating software. The robot uses an XON XOFF terminal that can send text-files one line at a time and the robot moves to the G-code coordinate accordingly. Extremely large drawings, up to 9 meters, are possible due to the portability design and wireless transmission of the G-code to the robot. The robot works on a closed loop system and its motion will be highly accurate, Due to an accelerometer and a gyroscope sensor used to correct its motion if there is an error because of uneven surface or wheels slipping on the surface.
