ENGR 161 Robot

Sep 2022 — Dec 2022

Project Description

Designed and built a "Mars Cargo Rover" as part of a three-person engineering team to complete autonomous navigation, obstacle traversal, and cargo delivery tasks. The robot was constructed using LEGO Technic components and a Raspberry Pi board, along with sensors including color, Hall effect, gyro, and ultrasonic.

The mechanical design featured a differential steering drivetrain and rear caster supports to maximize obstacle climbing ability. A cargo delivery system could secure different container shapes during transport and precisely drop cargo when triggered.

The software included a custom line-following algorithm and calibration functions to ensure reliable sensor readings under different lighting conditions.
