- Engineered a line-following rover using 3 IR proximity sensors, 3 ips sensors, a servo claw, and a DC motor for lifting, controlled via a MOSFET without a dedicated motor control board.
- Achieved near-100% reliability in line following and turning, despite challenges with turnaround maneuvers caused by the claw's high mounting position affecting balance, as it couldn't automatically lower due to the motor setup.
- Diagnosed and resolved a voltage drop issue (from 11V to 8V) by upgrading to heavier-gauge wiring, resulting in a threefold increase in rover speed.
- Utilized a two-sensor setup with backwards logic, maintaining consistent line detection with minimal wobble; identified that a third sensor could potentially improve turnaround accuracy.
- Controlled power to the servo and motor using MOSFETs gated by Basys-3 FPGA signals, demonstrating integration of digital logic with power electronics.
- Developed an IR receiver circuit with a band-pass filter, achieving signal detection up to 5 ft (exceeding the 3 ft requirement).
- Coded and synthesized Verilog designs in Vivado to process 1-3 kHz signals, showcasing proficiency in HDL and FPGA programming.
