Since the mid-1990s, RCPD and the College of Engineering have partnered to spearhead projects that address accessibility challenges for persons with disabilities. This work positively affects countless lives while informing future engineers of the ways that accessible and universal design principles are marketable and life-changing.
Each semester, ECE 480 faculty and senior students collaborate with RCPD’s Assistive Technology Specialist to tackle an array of engineering challenges, with one to two projects devoted to improving accessibility. Projects are typically proposed by persons with disabilities and then sponsored by corporate or private entities interested in accessible design. People with disabilities also serve as part of the expert team that guides concepts to completion.
Are you a person with a disability who has an idea for a future project? If so, tell us about the challenge at hand and how a team of electrical and computer engineering students can become involved in addressing it. Note that all submissions are public domain and that we cannot guarantee confidentiality or recognition.
RCPD Design Day Projects – Spring 2019
Sponsored in Part by Harold F. & Phyllis N. Wochholz and Marathon Oil.
The first-place winner was the Jungle Power Pod: A Photovoltaic Battery-Powered System for Common Portable Electronic Devices
- The Jungle Power Pod is a low-cost system for operating electronic devices.
- It is a universally designed device that is accessible to persons with visual and hearing impairments.
- This technical solution is intended for use in hospital rooms at the Bombardopolis Health Center in Haiti and remote households around the world.
The third place team was a collaboration between MSU Bikes and RCPD, producing the Intelligent Defense System: a portable sensor that mounts under the seat of a bicycle or can be handheld and alerts the user of approaching vehicles.
- This device will be able to detect approaching vehicles from behind. Side and front sensors can be considered in future projects.
- If a vehicle is approaching and possible collision is predicted it will alert the user in the following ways:
- An alarm or voice sound
- Flashing light (including flashes toward the approaching vehicle)
- A wireless signal could send information to a cell phone that the user is carrying or has mounted on their handlebars. The cell phone would then be able to alert the user with sound and light.
- Simplicity, reliability, and low cost will make this a product that has a good chance of high sales and mass production thereby saving more lives.

View photos of the project in Haiti.
- ECE 480 students during the spring 2018 semester will specify a power system and design a power control monitoring system for the OIH hospital in Bombardopolis Haiti.
- This will be used by the hospital to monitor the solar panels, wind generators, batteries, voltage inverters, engine generators and room power availability.
- A permanent wall mounted display panel in the hospital with a picture of the hospital floor plan and the power generation sources (wind mills, solar panels, batteries, generator) with a red -yellow- green LED could indicate where power is available on the hospital floor plan, this will provide a fast way to diagnose trouble areas.
- This microcontroller based panel should be independently powered with its own battery so it will continue to function even if the whole hospital looses power.
- The challenge is finding a design that is capable of withstanding a hurricane, may need to build custom units.
Proposal to Design and Construct an Acutator for a Prosthetic "Bionic" Arm
ECE 480 students during the Spring 2018 semester will work with Lee and his team to build the electronic control interface that will operate a motor in a 3-D printed hand to actuate grip
Previous project used RC type servos for actuation, these proved unsatisfactory, improved system needed
- Minimum function would be to control only one actuator to provide gripping. If time permits other degrees of freedom could be provided, such as individual finger movement or wrist rotation.
- Former RCPD student, Lee was born with missing left arm below his elbow
- Hasn't worn a prosthetic since the age of 14, felt he didn't need one
- Wearing a prosthetic would help him build muscle on his left side and balance the way he moves
- Student would like to custom build his own
Inclusive Sports Wheelchair
Sports wheelchair that fills need for athletes who are affected by upper body muscle asymmetry but who possess relatively complete lower body functionality.
Team started with a standard sports wheelchair and integrated a device that allows the chair to be powered by the athlete's legs rather than by his or her arms.
Device does not compromise the integrity of the wheelchair frame and allows the user to steer and brake easily despite his or her input limitations.
Innovative Tricycle Enables Individuals with Limited Motion
- This “rowing” powered tricycle lets the user with motoric disability define where to apply strength in a short range of motion.
- This system was created as part of a collaborative effort of the MSU College of Engineering and the Resource Center for Persons with Disabilities through their support of the Adaptive Sports and Recreation Club.
- While this unique propulsion system was custom designed to accommodate the athletes that will be using it, many other visitors on Design Day enjoyed zooming down the halls of engineering, see below. This universal designed system will undoubtedly be a long-lasting solution for the club.
Goal was to create a safe, durable, and ergonomic posterior posture walker that easily moves with the user during a sports application.
- Intent is to allow users to utilize their full body when exercising, rather than being constrained to a wheelchair.
- Device is intended to be used by persons with partial control over their lower limbs.
- Can be used on a variety of surfaces such as a track, turf, and a basketball court.
- New design included ergonomic handgrips, a foot shield for the back wheels, and a quick switch to lock/unlock the front wheels.
Precision Pointing Device for Blind Shooting Sports Enthusiasts Using Haptic Feedback
- New design has moved the camera to the gun where it is mounted similarly to a scope.
- The camera is able to see the target and bullseye.
- A microprocessor uses image recognition and sound feedback to guide the user to the target.
- Upgrade is not finalized, the microprocessor will eventually be moved to the gun along with the camera to make a complete system that can be used anywhere.
2017 UPDATE: Check out the final test video for this project on the right side of the page! Read about the project on WKAR.
- Aims to provide improved accommodations to blind individuals who wish to participate in recreational activities at the Demmer Center, such as archery and small caliber target practice.
- Current spotting scopes for precision pointing devices are heavy, making quick, precise movements impractical. These current systems do not guide the user towards the target but require cumbersome groping techniques and extensive human guidance for success.
- Project team members plan to replace the cumbersome spotting scopes with a directional multimodal feedback system using haptic signals and simultaneous audio changes that guide accurate target identification.
- This device will abolish the need for groping because the feedback will always point the user in the direction of the bullseye.
- This feedback can also give users external information like target distance, size of target, and wind speed.
