Source components and build an open source CoreXY 3D printer known as the Mercury 1.1

Tune and optimize printer performance for speed and accuracy

Install Klipper and create custom printer.cfg profile and macros

370x370x400 mm build volume

Sourced all components and organized a Bill of Materials

Fabricated ASA parts used in the printer with FDM on PRUSA MK3S+

Used a BTT Octopus motherboard with TMC2209 and TMC5160T Stepper Motor Drivers

Produced custom toolhead with CAD to accommodate sourced hotend

Prints at 300 mm/s speed, 5000 mm/s^2 acceleration, and a filament volumetric flow rate of 35 mm/s^3

Printer can be controlled over WiFi with Raspberry Pi or manually with 5" HDMI screen

Prints at over double the speed of a PRUSA MK3S+

Develop and fabricate a fully mechanical prosthetic finger

Implement a hybrid solution to satisfy both intricate and heavy gripping tasks

Load sensor indicating how much pressure is applied to a finger

Designed for partial/full finger loss

Used Fusion 360 to design entire hand assembly

Performed rapid prototyping to iterate and arrive at final design

Used an Arduino Nano, a pressure sensor, and LEDs to indicate force applied to finger

Implemented elastic bands

Combines 2 types of prosthetics: ratcheting and string actuated

Single finger lifts 4 pounds curled and 10 pounds uncurled

Accessible, cheap, and uses readily available components

Design won 2nd Place at CSULB Senior Design Expo

Design 15:1 and 23:1 cycloidal drive actuators

Implement cycloidal drives in Robot Arm

Designed actuator in Fusion 360

Used Python to generate cycloid

Used Scripts in CAD to design cycloidal discs

Backdrivable, compact, and runs smoothly with minimal vibration

Create a Quasi-Direct Drive Actuator with a brushless DC motor base

Implement a planetary gearbox housed above the BLDC motor with minimal components

Used Helical Gear Add-in feature in Fusion 360 to design planetary gearbox

Developed gearbox around 900W 22A 90KV BLDC Motor

Produced a Quasi-Direct Drive Actuator during research under Dr. Liu at CSULB

Created actuator for use in a future Robot Dog research project

Design and 3D print an electric cello with volume and tone knobs

Include a Bass Preamp with 3 Band Equalizer

Inspired by the Yamaha electric cello

Used canvas feature in Fusion 360 to design cello body and bout shape
