HUMAN ENGINEERING RESEARCH LABORATORIES (HERL)
SUMMER INTERNSHIPS
FOR UNDERGRADUATE STUDENTS

The Internship Program at HERL (Human Engineering Research Laboratories) provides a unique opportunity for undergraduate students to engage in a variety of educational, clinical, and research training activities at a state-of-the-art research facility. Engineering and clinical opportunities are available in many research areas related to the development and evaluation of new technologies and procedures to improve the mobility and quality of life for individuals with disabilities. The internship is typically 10-12 weeks in duration, 40 hours each week. Students are assigned to work on one or more projects throughout their internship depending on their interests and HERL's current research agenda. Projects may be mechanical in nature (design and fabrication of measurement devices or wheelchair accessories/equipment), electrical (circuit design and implementation), computer (programming interfaces for data collection, virtual reality, and visual output) or clinical (assistance with human subject testing, data entry, data analysis, and subject recruitment). Many interns are provided with initial training and assistance and then go on to work semi-independently on their respective projects. Supervision and mentorship are provided by experienced faculty and staff (research scientists, physiatrists, clinicians, engineers, and expert machinists). Throughout the internship, students receive didactic training in research methodology, scientific writing and presentation and engineering design and fabrication. At the end of the internship, each student will prepare a scientific paper and present their project in a formal student research symposium. For many students, the HERL Internship Program is the opportunity that helps them to decide which career direction to choose. In fact, several of the interns have gone on to enroll in the graduate programs in Bioengineering and Rehabilitation Science and Technology at the University of Pittsburgh and have continued to work at HERL as graduate researchers. Although most undergraduate interns work the summer months, there are occasionally openings throughout the year. High school students who are interested in learning more about rehabilitation engineering, therapies and research can also apply.

Project #2:
1) Ultrasonographic Evaluation of the Median Nerve in Manual Wheelchair Users
This study will compare nerve conduction studies with ultrasound images of the median nerve and wrist. We will also use ultrasound images to look for acute changes in carpal tunnel and median nerve anatomy before and after wheelchair propulsion. Comparisons may also be made between wheelchair propulsion biomechanics and ultrasound images.
2) Analysis of upper extremity biomechanics and repetitive strain injury. In this study the student will gain experience in the collection and analysis of kinetic and kinematic data related to upper extremity movement. This data will be compared to shoulder injury as defined by imaging studies and subject complaints.
Students involved with these project will aid in data collection and image and biomechanical data analysis. Students will learn how to use force, motion, and imaging instrumentation, data acquisition software and MATLAB post-processing.

PROJECT #3: Transfer Biomechanics
The study of how individuals with lower body paralysis move their bodies from one surface to another is poorly understood. Yet transfers may play a key role in the development of repetitive strain injuries of involving the wrists and shoulders. Understanding the ergonomics of transfers can lead to better techniques to perform transfers so as to reduce the likelihood of pain and injury.
This project will consist of working with a graduate student to collect and analyze biomechanical data on transfers from the wheelchair to a variety of surfaces with/or without an assistive aid (e.g., grab bar). The students will become acquainted with motion analysis systems, force plate and load cell instrumentation. He/she will also learn how to use Labview and Matlab software for basic signal acquisition and analysis.

Project #4: Smart Power Assistance Module (SPAM)
Description: The Concept of power assistance for a manual wheelchair represents a viable alternative for individuals who are unable to generate sufficient propulsion force to use a manual wheelchair, the traditional rear wheel hubs are replaced with motorized hubs that serve to magnify or reduce the propulsive force applied to the rear wheels by the user. In this project we will use sensors to detect obstacles and drop-offs (e.g., stairs, curbs, potholes) near the wheelchair, and use the motorized hubs to modify the forces applied to each wheel to avoid obstacles.
Students will be asked to
a) work on C++ language programming
b) do electronics work
c) use sterolithography machine to build some mechanical parts.

Skill that will be required include C++ language, electronics, software Solidworks.

Electric Powered Wheelchair for Use in Developing Countries (India)

This project entails working with a graduate student to design, and if time permits to build an electric powered wheelchair for use in developing countries. The target country for launch of this product is India with our partner the Artificial Limbs of India Manufacturing Company (ALIMCO). We have been working with ALIMCO for several years on the design of a robust manual wheelchair. This project is an extension of that work. Our goal is to design and create a prototype electric powered wheelchair that is durable, highly reliable, and easy to manufacture, and low cost (under $1,000 in India).

The undergraduate student will be working with one of my doctoral student who is responsible to me for the project. We will try to create CAD drawings for the mechanical and electrical components. Mock-ups will likely be created, but a prototype is not likely to be completed during the summer.

Design of a Third Generation Hand-Cycle

This project entails working on a hand-cycle for exercise by a person with a lower-extremity impairment. Hand-cycling a form of aerobic exercise like bicycling that can be done along with friends and family members. The goal of this project is to refine the design for pre-production and to convert the primary structural elements from steel to aluminum. A steel-framed prototype exists as well as documentation that can be used as a model. The aluminum prototype should be lighter, easier to manufacture, and include adjustments to fit the user.

Advisors - Rory A. Cooper, Ph.D., Ding Dan, Ph.D., and Donald M. Spaeth, Ph.D.
Graduate Student - Michelle Tolerico

Design of Electric Powered Wheelchair Datalogger

This project entails the design and prototyping of a simple compact datalogger that can be installed on nearly any electric powered wheelchair. The device must be simple to install, preferably with minimal tools and no special technical skills. We have developed several dataloggers for similar applications in the past, and a substantial amount of work can be drawn from these earlier prototypes.

Both mechanical and electronic design will be needed for this project. We want to be able to collect distance traveled, time traveled, speed, time of day traveled, and location (indoors vs outdoors). The inclusion of GPS would be a significant benefit. Downloading via a cellular phone would also be good. Data should be capable of being stored for at least 3 months. The device must be weather resistant, shock resistant, and tamper resistant.

Advisors - Rory A. Cooper, Ph.D.
Technical Support Staff - Mark McCartney

Design of Manual Wheelchair Rear Suspension System

This project entails the design and prototyping of a novel rear suspension system for a manual wheelchair. The goal is to reduce ride shock and vibration when ascending/descending curbs, and when negotiating uneven terrain. The device should be lightweight easy to install and adjust, and inexpensive. Ideally, the system would retrofit to many common manual wheelchairs.

The work of Andy Kwarciak will form the foundation for this project. I have a preliminary design that needs to be drawn in SolidWorks and/or FeatureCam. This project entails both the design and construction of a prototype. Testing will be conducted if time permits.
