1.3 IDENTIFYING CLIENT'S OBJECTIVES

SL.NO OBJECTIVES
1. The robot should be semi-automatic
2. The robot should be portable
3. The robot should be user friendly
4. The robot should drop the defined amount of rangoli powder

Problem definition version 1.1:

Design a semi automatic rangoli drawing robot which can draw various rangoli designs on the floor. The robot should be portable , user friendly and should draw freehand and dotted designs.

1.4 IDENTIFY CONSTRAINTS

SL.NO CONSTRAINTS
1. The weight of the robot should be less then or equal to 1.5 kgs
2. The dimensions of the robot should be 1ftx1ftx1ft.
3. The cost of the machine should not be more than Rs 7000/-
4. The size of the dots should be min 5x5 and max 10x10
5. There should be min 4 and max 21 dots per design.
6. The max rangoli powder used for 1 design in 200 gms

Problem definition version 1.2:

The rangoli drawing robot shouldn't exceed 1.5 kgs of weight. The dimensions of the robot should be 1ftx1ftx1ft. The cost of the machine should not exceed Rs 7000/-. The size of the dots must be min 5x5 and max 10x10 respectively. A single design should have min 4 and max 21 dots and max 200 gms of rangoli powder should be used in a single design.

1.5 ESTABLISH FUNCTIONS

SL.NO FUNCTIONS
1. The robot should draw various designs using rangoli
2. The robot should draw freehand and dotted designs
3. The robot should not smudge the already drawn rangoli design while while drawing overlapping figures.
4. Indicate the commencement of the robot
5. The rangoli powder should be stored in a bottle tightly to ensure non leakage
6. It should detect the amount of rangoli left in the bottle
7. It should indicate once the drawing is completed

Problem definition version 1.3:

The robot should draw various designs using rangoli and the designs must be freehand and dotted. The robot should not smudge the already drawn design while drawing over lapping figures.

1.6 MORE PRACTICAL USAGE

1)The robot can also be used for writing

2)The bot could also be used as an aid to teaching in pre-school where it could serve as an interactive and fun way to learn shapes, alphabets.

  1. In a large scale we can also use it to do markings on the ground.

1.12 THE LIST OF COMPONENTS USED

1.12.1 ACTUATORS

SL.NO NAME FUNCTION PRICE PLACE OF AVALIBILITY
1. STEPPER MOTORS The stepper motor will rotate a fixed angle according to the direction set for the stepper motor.
2. SG 90 MICRO servo motor High torque motor to control their rotation.

1.13 SUMMARY OF THE MECHANISM AND WORKING

1.13.1 MECHANISM

PEN PLOTTER MECHANISM (XY PLOTTER)

2 Stepper motors are attached to the 2 compartments moving to and fro according to the predetermined code and servo motor handles the pouring of the rangoli from the pen.

1.13.2 WORKING

2 Stepper motors are attached to the 2 compartments moving to and fro according to the predetermined code and servo motor handles the pouring of the rangoli from the pen. We are using a software named BENBOX in which we draw the required design.

1.14 TOOLS AND SOFTWARES USED

SL.NO NAME FUNCTION
1. ARDUINO IDE Used for writing code, compiling the code to check if any errors are there and uploading the code to the Arduino.
2. SOLDERING KIT Used to build and develop the model
3. BENBOX We have used BENBOX software for the design input , various design can be drawn using BENBOX.
