This paper presents two unique senior design projects that have been completed in a B.S. in Engineering Technology program. The first project’s objective was to design and build a ladder activity board (LAB) to experimentally measure and diagnose special-needs children’s learning skills. The LAB is developed to make physical therapist offices more time conscious and productive. The LAB has a dimension of 24 X18 inches and it is expected to keep the attention of children at their physical therapy diagnostics. The board is installed on a ladder system allowing it to be adjusted for each patient’s height. The activities that are installed on the board are expected to help children to learn their basic shapes, colors, and voices of different objects and animals that are built by basic mechanical and electrical circuits.
The LAB can be considered as an easy alternative for child development needs. The purpose is to have access to multiple exercises all in one product. The LAB is a product that will be used in a physical therapy office and could be purchased for the child to perform their physical therapy at home. In the times of COVID-19, this product will help families that cannot go into their physical therapist’s office. The final product is made from plywood with plastic features printed in 3D printers in the engineering technology department. The electrical components stimulating animal sounds and LED lights are installed on the panel in the back of the board. The functional block diagram, 3D-design of the overall LAB system, the flow chart that how the LAB operates, and the related Gantt chart of the project will be reported in the full paper. The LAB will be helping physical therapists to save time in the process of diagnosing and keeping track of a child’s progress. The board will also help the child learn cognitive skills such as recognizing colors, shapes and animals and entertain them while progressing in their physical therapy and special education settings.
The second unique senior design project reported in this paper is design and production of a temporary to semi-permanent solution for a replacement leg for a general canine. The need has been demonstrated by a pet dog who has lost a leg. The goal of this senior project is to design and build a prosthetic that can be used as an artificial leg for the animal. If the animal is still growing this project will help to design and build a product that can be either scaled, adjusted for a better fit, or different sizes as the dog develops. The other main goal of the project is to use easily accessible materials other than the 3D-filament that is not available to the general public. To achieve this goal, students only used the materials that can be found in big box stores such as Amazon, Walmart, Home Depot, etc. Students working on this project were very excited about enabling a pet to become fully ambulatory. The main goal of this second project is to design a 3D-printed dog leg replacement that will help the animal have a much better future. The testing of replacement leg to provide stable movement and walk will be reported in the paper. It is expected that this project will serve as a reference work for many canine owners to be able to help their own pets by using easy design and 3D-manufacturing techniques rather than time consuming and expensive traditional leg replacement methods.
