“This is a rangoli/sand-art-making robot. It has 2 servo motors controlled by an Arduino Uno prototyping board. It can draw different shapes.
What is your project about?
This project is about a robot that can draw and write on rangoli. It has two servo motors that are controlled by an Atmega328p microcontroller mounted on an Arduino Uno prototyping board.
Why did you decide to make it?
The reason for making this robot is to draw any shapes on the rangoli. The rangoli is being drawn by hand. And I am not good at making rangoli. So, I decided to make a robot. That can make rangoli for me instead.
How does it work?
It has two servo motors that are controlled by an Atmega328p microcontroller mounted on an Arduino Uno prototyping board. It works in the principle of inverse kinematics. The outline coordinates of the image to be drawn are stored in an array in Arduino code.”
