Overview
For my EGR-101 final, I designed and built a device to launch a ball at a target, from CAD in Fusion 360 down to the Raspberry Pi Pico motor control. I succeeded in hitting a target 10 feet away, 3 feet off the ground, with technical drawings and a written report.
Technical materials
What I learned
- Designed a dual friction-wheel ball launcher with an adjustable-angle launch ramp in Autodesk Fusion 360 to meet a formal engineering brief (hit a target 10 feet away, 3 feet off the ground)
- PWM motor speed control via an L298N driver, commanded from a Raspberry Pi Pico, to fine-tune launch velocity
- Multi-stage voltage regulation (12V to 5V to 3.3V) and ADC-based potentiometer input for user-adjustable control
- Delivered formal technical drawings and a written design report alongside the working device
