ENGR2330 - Intro to Mechanical Prototyping


Short course projects for the semester are listed below in chronological order.

A collaborative engineering experiment

"The Mechtopsy"


A complex electromechanical system is disassembled (as a group) in the real world and modeled and reassembled (virtually) using computer aided design (CAD) tools.

Using Structures, Joints, and Fasteners

The Box


Students draw inspiration from a theme of their choosing to design a box using different types of structures, multiple joining techniques, and a host of mechanical fasteners.


Final Projects


The final project was the design, fabrication, and testing of an underactuated hand. Underactuated systems have more degrees of freedom than actuators and typically rely on compliance in the system to determine the configuration. Student teams of three to four members generated three prototypes of their underactuated hands using laser-cut plywood, sheet metal, and 3D printing (fused deposition modeling or FDM).

Final prototypes were mounted to a robotic arm and competed in a grasping competition. Images from the competition are available in this photo gallery.
