Project Overview
This Analog System Workshop project involves designing and building an autonomous line follower robot capable of tracking and following a predefined path using infrared sensors. The robot demonstrates fundamental principles of analog electronics, sensor integration, and control systems.
Key Features
- Infrared sensor array for line detection
- Pulse width modulation driver for speed control
- Analog signal conditioning for sensor data
- Compact and efficient chassis design
Technical Implementation
We designed each circuit with KiCAD Schematic & Board Design tools. The robot uses an array of 6 IR sensors to detect the line position. The analog signals from sensors are processed through comparators and fed into the control system. A Comparator to compare which is black which is white and counter to indicate laps.
Challenges & Solutions
One major challenge was dealing with different lighting conditions affecting IR sensor readings. This was solved by implementing ambient light compensation and proper sensor calibration.
