- Engineered a line-following rover using three IR proximity sensors, three IPS sensors, a 3D-printed four-bar servo claw, and a DC lift motor—enabled pickup and release of an 2.5" box and lift up to 8".
- Utilized a two-sensor backward-logic line-follow setup; noted adding a third sensor could improve turnaround accuracy and reduce wobble.
- Controlled power to servo and motor via MOSFETs gated by Basys-3 FPGA signals, integrating digital logic with power electronics.
- Developed IR receiver circuit with band-pass filter, Op-amp, and Comparator; achieved reliable detection up to 5 ft (requirement: 3 ft).
- Coded and synthesized Verilog in Vivado for 1–3 kHz signal processing, demonstrating HDL proficiency.
- Achieved high line-following reliability; turnaround maneuvers occasionally drove rover off track due to high-mounted claw.
