Line Following Robot

Electrical prototyping and programming of a line-following robot
September 2017-December 2018
Built With: PCB, microcontroller, resistors, op amps, optical encoders, Hall-effect sensors Tool used: Soldering tools, oscilloscope, signal generator, digital multimeter
The lab component of the Sensors & Instrumentation course aimed at introducing the practical aspects of sensor implementation and interfacing. These aspects include awareness of component tolerances, noise, and various design trade-offs. Over the course of the term with a lab partner, the electronics for a small mobile robot was constructed with power regulation, a microcontroller, an integrated programmer microcontroller, and a variety of sensors. The sensor suite included a pushbutton, optical encoders to measure the rotation of the wheels, a Hall-effect sensor to measure the strength of a magnetic field, infrared light detection to follow a line on the ground, temperature measurement, and overall system current sensing. High-level programming was also done to configure the robot to utilize selected sensors to successfully navigate a course in the final design competition.
