Arduino Servilliance Mobile Robot

Want to make an Arduino UNO basic Security Servilliance robot lets Make it:
Supplies






These are the Basic componets that you have to make this Robot Accurately some are Optional
just like IR sensor and ultrasonic that are might not be very useful but in some cases they are needfull and required.
Having These Components


The Most Basic Components are : the 2 Whells 2 Motors and One chess Mobile Robot Body just like this image
That make the Structure of the Robot also having a one Motor driver in our case H bridge we Use.
Lets Wiring the Robot to Operate

After that wiring the Robot accurately and perfectly i also shared the complete mechanism see how to pins connect of laser Diode with Arduino and PIR sensor pinout with Arduino now connect both also connect the IR senosors and Ultrasonic sensor with Arduino wired up now lets jump to the made up logic behind this and do a actual connecting communicating between these components by Programming !
Understand Mechanism
1. System Initialization:
The Arduino powers up and initializes all connected components.
2. Random Movement:
The robot moves in random directions (forward, left, right, U-turn) using 2 DC motors controlled by Arduino.
3. Obstacle Detection:
The ultrasonic sensor constantly checks for obstacles ahead.
If an obstacle is detected within a certain distance, the robot changes direction to avoid collision.
4. Night Operation with IR Sensor:
The IR sensor helps in detecting objects in low-light or dark environments.
It ensures the robot can continue obstacle detection or line detection even at night.
5. Motion Detection:
The PIR motion sensor monitors for human or object movement.
On detecting motion:
- An LED inside the house turns ON to alert presence.
- The laser module activates and points a beam toward the moving object.
6. Continuous Operation:
The robot loops through these functions continuously, providing 24/7 patrolling and motion-based alerting.
Do a Program to Robot and Its Operate in Real World

So here is the Code
Lets jump to the Final Resuls here :
