Research, Innovation, Service, Entrepreneurship (RISE) Program – Mechanical Engineering Research Assistant – First Open Source Robotic Leg

First Open Source Robotic Leg

What it does:

Currently, the prosthetics research is very fragmented due to a lack of common hardware and software. Researchers around the world spend long hours and thousands of dollars to build their own prosthesis. When this is the case, researchers have hard time comparing their results and collaborating with one another, causing the prosthetics research to improve very slowly.

The overarching goal of the open-source robotic ankle and knee system is to create a common robotic ankle and knee system for researchers so that they can collaborate with one another and advance the prosthetics research rapidly.

What I did:

Designed and built the “How to Assemble” page of the first open source leg (opensourceleg.engin.umich.edu) by creating detailed assembly instructions including custom made videos using iMovie.

Working on design recommendations to reduce the number of parts and increase assembly efficiency.

Sami Shamoon College of Engineering – Mechanical Engineering Intern – Ballbot Project

Ballbot Project

What it does:

A ballbot is a mobile robot that can move omnidirectionally and thus very agile compared to other vehicles. Its dynamic motion helps it to move easily in crowded and narrow environments. For example, it can help carry instruments for the elderly at hospitals or homes.

Benchmark Project

What is ME450 – Capstone Project ?

“For the ME450 Capstone Project, students solve an open-ended mechanical engineering design problem including the broader considerations of performance, cost, safety, and societal impact.The problem must provide opportunities for creative mechanical design, fundamental analysis, and proof-of-concept prototyping.”

For more information about ME450 – Capstone Project visit here

What I have been doing:

While all other students were allowed to choose either a project or a team, I was able to choose my team AND my project through my good relationship with professors and friends.

I was part of the hardware team responsible for designing and manufacturing the hardware components of the system.

Bike Pump

Design for Manufacturability Project​

What it is:

The goal of this elective class is basically to pick and existing product on the market and make it better by making it more robust, modular, easier to assembly and cheaper to manufacture. The product my team and I picked is the bike pump above.

COURSE TOPICS:

  1. Customer requirements, product design specifications.
  2. Conceptual design, design principles.
  3. Major classes of manufacturing and assembly processes.
  4. Product platforms and modular design.
  5. Manufacturing tolerances and tolerance selection.
  6. Material and process selection.
  7. Design for assembly processes.
  8. Design for manufacturing processes.
  9. Taguchi method for robust design.
  10. Rapid prototyping and design for additive manufacturing.

What I did:​

Enhanced functionality and modularity of a bestseller bike pump by adding a snap-fit pressure gauge and a foot-stand using Kano’s product development methods.

Improved the bike pump’s manufacturability and robustness by reducing assembly time by 18% and cost by 20% using Taguchi’s robust design methods.

Design and Manufacturing II – Mechanical Engineering Team Member – Four Bar Linkage Project

ME350 – Design and Manufacturing III

What it does:

In this class, my team and I built and electromechanical four-bar linkage system from scratch that can pick up balls, sort them into colors and places them into baskets that correspond to certain colors.

COURSE TOPICS:

  1. Review of the design process and relevant design principles
  2. Application of basic materials and mechanics to mechanical design
  3. Analysis and synthesis with focus on selection methods for basic off­the­shelf mechanical components which may incude gears, bearings, springs, power screws, and fasteners
  4. Basic kinematic and kinetostatic analysis/synthesis of mechanisms such as four bar linkages
  5. Selection and application of motors based upon predictive models and motor curves
  6. Design of mechatronic systems for given motion/power requirements
  7. Analysis of load and power flow through transmission systems including those with linkages
  8. Preparation of engineering drawings and manufacturing plans, selecting the appropriate materials and manufacturing processes based upon geometry, loading and tolerances
  9. Design, build and assemble mechanical systems using standard machine shop tools (manual mill, lathe, drill, waterjet cutter, and laser cutter)
  10. Test and evaluate simple mechanical and mechatronic systems and components for performance and failure behavior using physical and virtual prototypes

Source

What I did:

Designed an electromechanical four-bar linkage system with an Arduino microcontroller, a DC motor and color sensor using Solidworks and simulated its kinetics such as its power consumption using ADAMS software.

Created engineering drawings, GD&T and BOM to manufacture its parts using 3D Printing, Mill and Lathe.

Makeathon 2018 – Engineering Team Leader – Design and Prototype of an Interactive Display for Carasso Science Park

Makeathon – Design, Build and Test of an Interactive Display for Carasso Science Park Under 72-Hours

What it is:

Attended a 72-hour Makeathon in which a team of 5 engineers and I needed to design, build and test an interactive display for kids that shows why the earth orbits around the sun using the concept that a larger mass pulls a lighter mass towards itself.

What I did:

Led a team of 5 including international engineers and designers to design, build and test an interactive product that shows why the earth orbits around the sun using the concept that a larger mass pulls a lighter mass towards itself.

Won 2nd place in the Makeathon competition and was chosen the best design by the Carasso Science Park representative.

Makeathon 2017 Case Competition: Future City – 2nd Place Winner and Team Leader – Autonomous Car Project

Makeathon Case Competition 2017: Future City

What Makeathon is:

“Makeathon is a 36-Hour Prototyping and Design Competition held annually at the University of Michigan. The competition aims to bring together the University’s brightest and most creative students and give them the tools they need to build something truly awesome.”

Students who attend Makeathon can choose to attend either Makeathon Case Competition or Makeathon Open Ended Design Challenge. My team and I attended Makeathon Case Competition in which students are assigned a challenge by company representatives. We were assigned by Bosch and TI representatives to build an autonomous mini car that could navigate in a mini city, going through tunnels, stopping at red lights and stop signs. 

For more information visit Makeathon’s website here.

What I did:

Led three engineers to build an autonomous and remote-controlled mini car in less than 36 hours.

Modeled a vehicle chassis using Fusion 360 and manufactured parts to mount the electronics using 3D printing.

Presented the final vehicle to a panel of corporate representatives and was awarded 2nd
