1. Line Following Robot

The line following Robot is a classic entry point into robotics. It offers a tangible and engaging way to learn fundamental robotics concepts. This project involves building a small robot autonomously following a line, using sensors to detect the line and motors to steer itself. Its popularity comes from the balance it strikes between educational value and achievable complexity.

A line-following robot uses infrared (IR) or optical sensors to distinguish between the line and the surface. These sensors emit light and measure the reflected light intensity. A darker line reflects less light than a lighter surface, allowing the robot to detect the line’s edges. This data is then sent to a microcontroller, such as an Arduino, which acts as the robot’s brain.

The microcontroller processes the sensor readings and controls the motors. Motor drivers receive signals from the microcontroller and adjust the power to each wheel. This allows the robot to turn and stay on the line. A simple chassis, typically with four or two wheels and a caster wheel, forms the robot’s physical structure.

Features:

• IR or Optical Sensors: Detect the line by measuring reflected light.
• Microcontroller (e.g., Arduino): Processes sensor data and controls motors.
• Motor Drivers: Regulate power to the wheel motors.
• Chassis: Provides a platform for mounting components.

Pros:

• Low Cost: Components are readily available and affordable.
• Clear Success Criteria: The robot either follows the line, or it doesn’t. This makes progress assessment simple.
• Scalable Complexity: Start with basic line following and add features like speed control or obstacle avoidance.
• Fundamental Learning: Introduces core concepts like sensor integration and control loops.

Cons:
