1.2 Basic Survey and requirements.

              Table 2: Observation from a literature survey

SI.No.	Observation from survey	Requirements
1.	Weight of machine	Bot should be easily movable so the weight should be as less as possible
2.	Cost	Bot should be built with minimum budget
3.	Number of tunes to be played by bot	Good to listen more tunes played by bot
4.	Material to be used	Material used should not be rough and it's good to have minimum number of holes or cracks in it
5.	Controlling the bot by	Keypad

1.3 Identifying Client's Objectives

Step 1: Prepare a list of design objectives

              Table 3: Objectives identified

Sl.No.	Objectives
1.	The bot should be Portable
2.	The bot should be user friendly with smooth surface
3.	The bot should not have any sharp edges
4.	Aesthetics
5.	Maintenance

Problem definition version 1.1:-

Design a portable bot which must user friendly with no sharp edges and the bot must not be carrying the xylophone and with the rechargeable battery.

1.4 Identify the constraints

Step 1: Prepare a list of design constraints

              Table 4 :Identify the constraints

Sl.NO.	Constraints
1.	The cost must not exceed three thousand five hundred
2.	The maximum weight must not exceed three to four kilogram
3.	The bot must play the music for at least three minutes
4.	The total size of the bot be 9 inch by 7 inch by 3 inch
5.	Deminisions of the xylophone be 7inch by 4 inch by 1.6 inch
6.	The bot must be able to play at least two to three tunes
7.	The bot must not carry Xylophone

Problem definition version 1.2:-

Design a portable, user friendly bot without carrying the xylophone. The bot should weigh maximum up to 4kg with size of 9 inch by 7 inch by 3 inch without any sharp edges playing two to three tunes for around three minutes. The xylophone should be of 7inch by 4 inch by 1.6 inch and the overall cost range must not exceed three thousand.

Step 1: Prepare a list of design functions

             Table 5 :Identify the functions

Sl.NO.	functions
1.	Play xylophone
2.	Blinking RGB LED lights while performing
3.	Give an alert message when music/tune is about to get over
4.	Select the tune

Problem definition version 1.3:-

Design a portable, user friendly bot which works on electricity playing music with xylophone as a musical instrument without carrying it and blinking LED lights while performing. The bot should weigh maximum up to 4kg with size of 9 inch by 7 inch by 3 inch without any sharp edges, playing tunes and alerting the user when the music gets over. The xylophone should be of 7inch by 4 inch by 1.6 inch .There should be an option for user to select and play the tune. The overall range of cost must not exceed three thousand five hundred.
