QUESTION :

The description and the condition of the Vacuum Robot is shown below. Based on the description and condition, draw a simple logic circuit along with it's truth table. Do not use any electronic components, use different types of logic gates such as NOT, OR, AND gate.

.

Vacuum Robot

The Vacuum robot will move up and down the stairs by detecting the immediate surroundings.

Conditions

-From the problem statement, there are two different outputs (Up & Down) moving the stairs

- Let Up represents binary 1 and Down represents binary 0 since there are only two outputs

Input

Based on the surroundings, it will move up and down the stairs:

1) Since the vacuum robot is moving only on stairs, when it senses the stairs are over, that is, when it senses the flat surface, the output will be toggled.

2) When the obstacle comes in front of the vacuum robot while moving up and down the stairs

Input	Binary	Condition
P	0	Does not encounter a flat surface
	1	Encounters a flat surface
Q	0	Does not meet an obstacle while moving
	1	Meet an obstacle

The format of the answer can be shown in the picture below
