Abstract

This work-in-progress paper will describe the development of a low-cost and versatile hardware kit designed to enable students to work at home on design projects in a first-year Mechanical Engineering design course at XX University. The standard in-person version of the course included lectures, which were taught in traditional lecture halls, and labs, which were conducted in the Design Lab. In this in-person environment, students could learn to use fabrication equipment, including hand tools, basic shop equipment, laser cutters, and 3D printers. The hands-on design projects were critical for enabling students to apply and master certain class concepts at a deeper level, as well as gain project management, communication, and teamwork skills. The remote teaching setting has restricted students from accessing the Design Lab and associated tools usually used for these projects.

There is therefore an urgent need to develop hardware kits that can be shipped to students’ homes to enable them to perform hands-on design projects and meet the same learning objectives as those created for the in-person version. The hardware kits must be versatile enough that the students can create different solutions for an open-ended design project, yet easy enough to use at home with only the supplied tools. To avoid an additional financial burden to students, the kits must be relatively low cost. Finally, the components need to be safe to operate within a small space in a home environment and relatively easy to remotely debug when students encounter problems.

This paper presents the final hardware kit content and associated design projects. The key features that make the kits low-cost and versatile will be discussed. We will also document the kit content development process for different functional modules, including energy sources, control methods, structural components, custom-manufactured parts, fasteners, and tools. We will present alternative components considered with the corresponding tests that were performed, and reasoning for the final parts selected. We will also discuss the challenges encountered during the kit content development and logistics management, including part sourcing, manufacturing, packaging, and shipping, and we will provide suggestions to future developers.

We will assess the effectiveness of the hardware kits to facilitate students’ design activities from multiple sources, including student feedback and instructional team observation and feedback. We will evaluate the contents of the kit, including which materials and tools were the most versus the least useful, as well as which were the easiest versus the most difficult to work with. We will also evaluate the effectiveness of the design project, including assessing the value of the in-home fabrication and building activities, as well as the successes and challenges of remote teamwork. Although the hardware kit described in this paper was motivated by the remote teaching forced by the COVID-19 pandemic, it can also be used for design courses that are intended to be online.
