To design and develop a compact, low-cost, and efficient Scribble Bot prototype that can automatically move on a drawing surface in different directions and create various patterns, shapes, and designs using a pen. The prototype aims to demonstrate automated drawing through controlled motor movements while maintaining stability, accuracy, and proper pen contact with the drawing surface. It should be simple to operate, easy to assemble, reliable in operation, and capable of producing repeatable drawings with minimum manual effort.

Sl. No	Objectives
1	Easy movement
2	Different drawing patterns
3	firm pen holding
4	easy start and stop
5	smooth operation

The problem is to design and develop a Scribble Bot that can move smoothly on a surface and create continuous patterns or scribbles using a pen. The bot should have a maximum weight of 4 kg and be developed within a budget of ₹5000. It should consume less than 10 W of power and operate continuously for at least 30 minutes on a single battery charge. The pen must be firmly held and adjustable to maintain proper contact with the drawing surface. The system should operate using a 5–12 V DC power supply, while the motors and wheels should provide stable movement with minimum vibration. The design must satisfy these constraints while ensuring reliable and consistent drawing performance.

The problem is to design and develop a Scribble Bot that can move smoothly in different directions on a drawing surface and control the movement speed for accurate drawing. It should be able to raise and lower the pen when required and use the pen to create scribbles, patterns, and different designs on paper. The bot must efficiently manage electrical power to operate its components, maintain stable movement while drawing, and stop its movement when the drawing task is completed or when it is switched off.

	SI.NO	Functions
	1	The bot moves smoothly in different directions on drawing surface.
	2	The bot raises and lowers the pen as required during drawing.
	3	The bot adjusts its movement speed for controlled and accurate drawing.
	4	The bot uses pen to create scribbes,patterns, and drawings on paper.
	5	The bot uses and manages electrical power to operate its components efficiently.
	6	The bot maintains stable movement while drawing.
	7	The bot creates different patterns and designs on the drawing surface.
	8	The bot stops its movement when the drawing task is completed oe when it is switched off.
