Task 2.1: For the chosen need statement, write the problem definition

“Design a portable sand art machine which interacts via remote controls and has a good battery backup, less maintenance issues and rugged nature .The machine should include a erasing facility to make the work more easy and must be able to draw at least 3 different textures on sand. The cost and weight of the machine should not exceed 3000rs and 2kgs respectively .The machine should draw patterns within a dimension limit of 1.2m*1.2m”

Task 2.2: Write Use case diagram to represent the above system

Task 2.3: Functional Structure (Write detailed system sub functions for each Use case)

Use case 1 Collect the data	1.Indicate the activation of machine with indicators 2.Indicte the successful analysis of the data
Use case 2 Pour the sand on the work space	1.Ready the working space 2.Position the machine at the center of the work space with sand 3.Check for the proper operation of the tools
Use case 3 Drawing the pattern	1.Position the different sand art tools over the sand 2.Control the machine via RC remote and move the tool in the required direction 3.Drawing the patterns wherever the machine is moved via remote
Use case 4 Erasing the drawing	1.Check for the completion of the work with the drawn patterns 2.Emerging of the wiping/erasing tool 3.Movement of the tools in different directions to erase the patterns

Task 2.2: List the inputs, outputs of the system and represent black box model :

Inputs	Outputs
1.Energy through battery	1.Emerging of particular tool
2.RC remote control	2.Drawing patterns
3.Directions	3.Movement in different directions
4.Selection of pattern	4.Erasing the drawing if required
