In nature, some animals have an exoskeleton that provides protection, strength, and stability to the organism, but in engineering, an exoskeleton refers to a device that augments or aids human ability. Since the 1890s, engineers have been designing exoskeletal devices, and conducting research into the possible uses of such devices. These bio-inspired mechanisms do not necessarily relate to a robotic device, though since the 1900s, robotic principles have been applied to the design of exoskeletons making their development a subfield in robotic research. There are different multiple types of exoskeletons that target different areas of the human body, and the targeted area depends on the need of the device. Usually, the devices are developed for medical or military usage; for this project, the focus is on medical development of an automated elbow joint to assist in rehabilitation. This project is being developed for therapeutic purposes in conjunction between Arizona State University and Mayo Clinic. Because of the nature of this project, I am responsible for the development of a lightweight brace that could be applied to the elbow joint that was designed by Dr. Kevin Hollander. In this project, my research centered on the use of the Wilmer orthosis brace design, and its possible application to the exoskeleton elbow being developed for Mayo Clinic. This brace is a lightweight solution that provides extra comfort to the user.

Online learning has been more prevalent since the rapid increase of the technology field, this paper examines if the interactivity of an online learning website can affect learning, usability, and time spent interacting. Participants were collected from Amazon Mechanical Turk, and they were compensated $1.00 for their time. 39 participants received one of three online learning conditions on the ideal gas law with varying levels of interactivity (video, simulation, quiz). The participants took a pretest, interacted with their condition for a set time, then completed a posttest and a usability survey. An ANOVA was conducted on time, usability, and posttest transfer scores. A repeated measures ANOVA was conducted on pretest and posttest recall scores. There was no significance found for learning, usability, or time spent interacting with the online learning platform. Further studies should consider exposing participants to learning materials for longer periods of time.

Toy hacks modify commercially available toys to be more easily used by people with motor disabilities, and donate them to schools, families, or toy libraries. Switch-adapting a toy adds an audio jack to allow an assistive technology (AT) switch to be plugged in. Switch-adapted toys help children develop essential skills through play. Hacking toys is helpful because toys that come with AT switches are often significantly more expensive than their unadapted counterparts. Toy hacks are also an opportunity to teach and practice engineering skills such as soldering and technical problem solving. Many resources are available online to assist makers with hosting toy hacks, but most of them lack information on holding the event. To fill this gap, the authors created a toy hack guide website, drawing from experience hosting two toy hacks. It walks users through steps like choosing the size of the event, the materials that need to be purchased, and connects them to other existing resources. In the future, it will be used to help people host more successful toy hacks.

During a joint ASU-Prescott College visit to the Maasai Mara in Kenya in June-July 2018, it became obvious that many Maasai women produce beadwork sold locally to help support their families. The difficulties they face include inconsistent sales due to lack of customers, lulls in tourism, and unfair competition. During this visit, the idea of selling the crafts online via Etsy was suggested. It received overwhelming support from the community through MERC, the The Maasai Education, Research and Conservation Institute.

In this paper, we discuss the methods and requirements to simulate a soft bodied beam using traditional rigid body kinematics to produce motion inspired by eels. Eels produce a form of undulatory locomotion called anguilliform locomotion that propagates waves throughout the entire body. The system that we are analyzing is a flexible 3D printed beam being actively driven by a servo motor. Using the simulation, we also analyze different parameters for these spines to maximize the linear speed of the system.

Patient identification is becoming more crucially important, particularly as healthcare is becoming more data based and automated. Patient misidentification can cause a series of issues that affect patient safety and the quality of care, including increased time and money from the medical institution. Additionally, with the lack of standardization for identifying patients, interoperability is limited and Health Information Exchange cannot be optimized, One partial solution to the problem would be the implementation of a Unique Patient Identifier system; however, the United States has had some controversy over the implementation of such as system in the past as Congress prohibited any funding from going towards a UPI system in 1998 after HIPAA introduced a Unique Patient Identifier mandate in 1996. However, with more than 2 decades passing since the Congressional ban, the general American perception of Unique Patient Identifiers is not well known. This study attempts to answer the question of the current American perception of the implementation of a UPI system through an informational survey that induces critical thinking when answering qualitative questions with supportive quantitative questions. Participants were generally in favor of the implementation of a UPI system, and through a Chi-square analysis, it was shown that there was an association between knowledge learned about Unique Patient Identifiers in relation to the current identification system and developing a positive perception towards UPI implementation; however, this study cannot be generalized to the public as the sample size was not large enough and was not representative of the entire population. Still, future research should be conducted in relation to this subject as UPIs are a potential solution to our current “identity crisis”.

After the wind tunnels in the SIM building and Innovation Hub were donated or lost, Dr. Rajadas requested a new wind tunnel be designed, developed, and fabricated using facilities and resources available on ASU Polytech. Over 6 months, a single student was tasked with running the CAD modeling process, undergoing the revision stages, and welding/fabricating the tunnel by the end of Fall 2021.

With FDM printing becoming ubiquitous within the commercial and private sectors, there are many who would want to print a part without supports for a variety of reasons. Usually, they want to prints a part with difficult to reach places that would make it impossible to remove any support material without damaging the part. I will be going over options to consider when designing parts to ensure a given model will be able to be printed without support material.
