Conceptual design - P-Division-2018-2019/Team-4 GitHub Wiki

For the need statement given formulate the problem definition by listing objectives,constraints and functions.

Problem definition:

               Prepare a bot which must cost within Rs.5000 which digs through land and collects mud samples which can work on all sorts of roads, which also works from a distance of 10 meters from the controller and whose holding capacity should be 500 grams. The main objective of the bot should be to dig, collect and store the excavated material. It should carry a minimum load of 100 grams at a stretch and should be also able to transport,must have a strong outer body with high battery life so that it could work for longer period of time without breakdown and must be efficient and reliable and should indicate by a buzzer that the work is done.The bot should be controlled by wireless means.

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

Inputs	Outputs
Data	Movement of the bot
Battery(cell)	Rotation of the arm
	Excavation

List the functions of the system.

1.Receive the signal and move accordingly.

2.Movement.

3.Excavating the material.

4.Storing the excavated material.

Draw the functional tree

Write the glass box representation of the system in terms of functional blocks(requirements in the system with respect to user actions)

of achieving the functions.

Functions	Mean 1	Mean 2	Mean 3	Mean 4
1. Receiving signals	Wired	Wireless	Voice control	Hand motion
2. Moving according to the signals	Wheels	Roller	Robotic legs	Flight
3. Excavating the material	Toothed picker	Toothless sharp picker	Robotic arm	Driller and separate picker
4. Storing the excavated material	Storage box on the bot	Separate storage box	-	-
