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.


  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


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.
