The Sharpie Dotifier

Postby ThePyroElectro » Tue Dec 14, 2010 4:05 pm

The Sharpie Dotifier

Description:
The Sharpie Dotifier has limitations and strengths. It can draw stuff out using a sharpie pen and while it does make mistakes from jittery motion from time to time, overall it draws perfectly. However, the limitations do stand out. Not being able to draw a picture larger than 100x50 pixels, or to use more than 1 color seems almost ridiculous in this day and age. But! The Sharpie Dotifier wasn't meant to be cutting edge, rather to show how a robotic arm can be put to intelligent and useful work with some ingenuity.

MPLAB from microchip.

ok thanks sir... :) instead of PIC controller can we use another 1? and what is the reason behind using the PIC18F452??

Most of my projects used 18F452, that is why.

Another PIC could be used, but depending upon the series of PIC microcontroller, you may not be able to use the same code and C18 compiler that I used.

okk... n how the paint file was converted into the command? i mean how the c++ scripting program wrote? n how it is converted into the .BMP file? 'BMP' stands for what?

I drew the picture in paint and saved as a monochrome BMP. Then I wrote a C++ program to make a 2-d array out of the picture. And afterward the C++ program spit out commands in the form of a script that would tell the sharpie dotifier what servos to move and where.

ok... is their is any another software used for this sending a command towards the pic controller??? RS232 used for interfacing purpose... but how the actual command send??
like when your going to work on 8051 controller,we program in KEIL software,n then hex file we are going to download on kit using 'flashmagic' software. so for this purpose what you had used??

This project is gonig to make the dot of send pictute or text.. if i want to draw it continuously without dot, means same as that of sent message what should be changes ?? N if we use the choke instead of pen,for drawing diagrams on the board,then the servo n stepper requirement for project will increase???? simply my question is can i make this system for classroom board,if yes.. then what should be changes?

Sorry, it is difficult for me to understand your questions.

To adapt this project for use on a school white-board would be very challenging given that this is a robot arm drawing with many degrees-of-freedom that must be navigated.

It would be wise to make something more like a 2-d plotter with motors to control the stage movement on X and Y-axis then a simple motor on the state to push a pen down and then back up to put the 'dot'.

Using a robot arm is much more than is required.

Not variable. Just a normal sharpie style felt pen.
