3.3 IDENTIFYING CLIENT OBJECTIVE

Problem Statement: Traditional manual rangoli creation is a time-consuming process requiring significant artistic skill, which often leads to messy spillage and inconsistent execution. The core objective is to design an automated solution that simplifies the creation of artwork, making beautiful rangoli patterns accessible and effortless for anyone interested in the craft

3.4 Identifying the Constraint

Problem Statement: To automate the artwork creation successfully, the system must autonomously execute functional tasks. It needs to accept JPEG design templates loaded directly via USB, suggest options based on user preferences, and draw specific geometric or floral patterns automatically. Furthermore, it must offer simple user instructions, allow saving/sharing capabilities, and function reliably without a companion app while including an emergency stop for operational safety

3.5 Establishing of function

Problem Statement: The system must operate within strict physical, financial, and technical limitations. The design is strictly constrained to a compact, non-portable volume of 1 cubic foot, a weight between 450–560 grams, and a maximum production budget of $31.29. Logistically, it must run for 10 continuous minutes using a single 9V battery, handle a maximum of 3 colors cleanly with line thicknesses of 3–5 cm, and operate entirely without a standalone digital display or smartphone app interface.

3.6 PROBLEM DEFINATION

Design and develop a compact, user-friendly and safe Rangoli Bot that can automatically draw selected geometric and floral Rangoli designs. The objectives of the Rangoli Bot are to provide accurate, time-saving, portable and easy operation, with support for multiple colours and different Rangoli designs. The constraints are that the bot should have a size of approximately 1 ft × 1 ft × 1 ft, weigh around 450–560 g, cost is approximately 3k-5k, operate using a 9 V battery for about 10 minutes continuously, support a maximum of 3 colours and maintain a Rangoli line thickness of 3–5 cm. The functions of the bot are to automatically draw the selected design, move smoothly along the required drawing path, accurately position the powder-dispensing nozzle, control the amount of Rangoli powder released, dispense different colours without mixing, store and select designs, accept designs through a USB drive, provide simple operating instructions, allow start, pause and stop operations, detect powder blockage or incorrect patterns, alert the user when the battery is low, prevent excessive powder spillage and provide an emergency-stop function.
