As part of my senior year curriculum at Northeastern, I participated in the

Mechanical Engineering Capstone Program

, our equivalent of a senior design project. Capstone offers students the opportunity to integrate their academic and experiential learning into a multi-semester team project with real-world applications.

For my Capstone project, called the

Critter Catcher

, I collaborated with a team of four engineering students to design and manufacture a

humane bug catcher

capable of safely capturing flying insects. From our efforts, we earned an award for

Best Iterative Design

at Northeastern University’s Engineering Showcase!

The Critter Catcher was developed through an extensive iterative engineering process. Multiple rounds of testing, and prototyping were underwent to create the device we see today. This process included:

•

Market Research & Problem Identification:

Analyzing existing insect catchers and identifying gaps in usability, effectiveness, and humane treatment.
•

Concept Development:

Brainstorming solutions, evaluating different capture mechanisms, and selecting a vacuum-powered design.
•

Prototyping & Testing:

Creating CAD models, 3D-printed prototypes, and refining the design based on ergonomic testing and live bee trials.
•

Iteration & Improvement:

Enhancing user comfort, containment security, and suction power through multiple design cycles.

As the

lead of the electronic subsystem

, my primary responsibility was developing and implementing the device’s electronics. I programmed an

Arduino Pro Mini

to control the fan’s duty cycle, allowing for

variable fan speed adjustment

. Additionally, I integrated key electronic components, including an on-off button and a rechargeable lithium-ion battery to enhance portability. This role required expertise in

mechanical engineering, electrical engineering, and computer science

, as I had to ensure all hardware fit seamlessly within the device while maintaining functionality and ease of use.

The Critter Catcher has potential applications beyond consumer use, including

beekeeping, entomological research, and conservation efforts

. Humane testing with the Northeastern Bee Society and New England Beekeeping confirmed its

effectiveness and safety for live insects

.Through this project, I gained valuable experience in

mechanical design, rapid prototyping, team collaboration, and user-centered design

. This experience reinforced the importance of

iterative problem-solving, interdisciplinary communication, and sustainability-focused engineering
