Line-Following Car

Overview

I designed and built a small car using laser-cut components controlled with a PIC32 microcontroller using a camera for sensory feedback for line-following.

Implementation

Components

5 ft² Clear acrylic for laser-cutting
Assorted screws, nuts, washers, spacers
10x10 in PCB with PIC32MX270F256D designed for compatibility with components detailed below
2 rechargable LI batteries
1 camera
2 rotary motors
1 LCD touchscreen

Chassis

Chassis housing for PCB, batteries, motors, and camera designed to be put together from laser-cut parts

Wheels

Laser-cut wheel designed for low weight per strength ratio

Motor Clasp

Clasp for motors designed from laser-cut pieces
