Build an Obstacle-Avoiding Robot

Lecture 1: Robot Chassis and Motor Control:

• Description: We begin with the physical build. You will assemble the robot chassis, attach the motors and wheels, and understand how to power them. This class focuses on the hardware and the basics of controlling motion.
• Key Concepts: Robot chassis assembly, DC geared motors, motor driver (L298N) functions, and basic wiring.
• Hands-on Project: Assembling the robot chassis and wiring the motors to the motor driver.

Lecture 2: Arduino Integration and Basic Movement:

• Description: We'll connect the motor driver to the Arduino, giving the microcontroller control over the motors. 
• Key Concepts: Connecting the Arduino to the motor driver, controlling motor direction and speed, creating functions for basic movements 
• Hands-on Project: Programming the robot to perform a basic sequence of movements (e.g., move forward for 2 seconds, turn right, move forward again).

Lecture 3: Ultrasonic Sensor and Distance Measurement:

• Description: This is where the robot becomes "smart." We will introduce the HC-SR04 ultrasonic sensor, which acts as the robot's eyes. You'll learn how this sensor works and write code to measure the distance to objects.
• Key Concepts: How ultrasonic sensors work (ping-echo) calculating distance, and serial communication for debugging sensor readings.

Hands-on Project: Mounting the ultrasonic sensor on the robot and writing a program to continuously measure and print the distance to an object in front of it.

Lecture 4: Obstacle Detection and Avoidance Logic:

• Description: Now we combine everything. You'll write the core logic that allows the robot to make decisions based on sensor data. We will use if-else statements to tell the robot what to do when it detects an obstacle.
• Key Concepts: Conditional statements (if, else if, else), defining a "safe distance," and creating a decision-making loop for autonomous navigation.
• Hands-on Project: Writing the complete program for obstacle avoidance: if the distance is too short, the robot should stop, reverse, and turn to find a clear path.
