Project Summary

Students with a physical disability are twice as likely to be inactive during the week, which not only limits their physical activity, but also reduces these students’ opportunity to develop important social and leadership skills. The Overcomer is a form of assistive technology that helps individuals who have physical disabilities become more active in physical and social activities from their wheelchair, walker, or stander. The Overcomer intends to help users interact, socialize, and enjoy their time being active. Current prototypes of the Overcomer include both lower and upper extremity attachments, which include help for users to play hockey, baseball, and soccer. These prototypes can be improved on to becomes more reliable and stronger, as well as being more easily manufactured at an affordable price. There are currently no comparable products on the market.

The goal of this project is to further help develop the Overcomer for users to be able to throw and catch a ball with ease and excitement while making the product more adjustable to multiple mobile aids. It should also be easy to lift and attach the device and not interfere with the mobile aids it is being attached to. In addition to being user-friendly, The Overcomer needs to be able to be transported or stored conveniently. The end product needs to have low manufacturing costs with a goal market price of $500-$1200.

Objective Statement

The Overcomer assists those with limited motor functions to participate in sports.

Stakeholders and Key Concerns

Stakeholders Key Concerns
Individuals with limited motor function (Ages 4- 15) The device works effectively and is aesthetically pleasing
Their parents or caregivers That The Overcomer is affordable, can store easily, and easy to attach
Occupational Therapists That The Overcomer is affordable, they have storage for it, and kids like to use it
Joe Kabes - Overcomer Founder That the device works as intended, manufacturing process is easy to follow and can be replicated
Gym teachers and coaches That they have storage for the device, all types of children are willing to interact with a child who is using The Overcomer
MSD Team 19046 That a working prototype is designed, and all of the work is organized
Our Sponsors: RIT MSD, Autodesk Keeping the team on track and doing what needs to be done
Device Manufacturer Easy manufacturing process, can be replicated, low cost

Use Cases

A common example of the use of the Overcomer is that a child with limited motor functions who uses a wheelchair will need to utilize the device to play catch with their parent/ caregiver and another able-bodied child.

Team Value and Norms

Values Punctuality Thorough Accurate Professional & Ethical Collaborative Committed
Meets Be on time for meetings and class, if you have a planned absence make the team aware at least 48 hours in advance. If something comes up after that let the team know ASAP. Follows general structure determined by team, work is concise and clear to all other team members, all work is uploaded/organized on google drive. The work completed by the member contains a few errors that must be corrected. The basic approach to problem solving is good, and the errors are relatively minor and could be readily corrected through normal peer review and checking. The work was corrected through consultation with the team members or faculty guide. Behaves responsibly in all situations related to project work and respects all individual team members. Team member does not demean other team members’ work. The team member is completing work that is not counterproductive and achieves the goals of the collective team. The team member is carrying their fair share of the workload and is dedicated to goals set by the team as a collective unit.
Needs Improvement Is consistently late or skipping out early to/from class or meetings, for example: comes late with coffee, without notifying team. Follows parts of structure, does not explain work completed fully, all work is uploaded/organized on google drive. The work completed by the member contains many errors that must be corrected. While the basic approach to problem solving may be ok, the actual work completed needs to be largely re-done in order to be useful to the team. Some things were not done by the team member, that should have been obvious to complete. Behaves responsibly in most situations related to project work and respects all individual team members. Team member does not demean other team members’ work. Team member completes work that is acting against others’ work or is not meeting the goals of the collective team Team member is not interested in the work, doesn’t take on as many tasks from the project.
Unsatisfactory Consistently misses Friday meetings/ class without notifying team. Does not follow structure determined by the team, work is not uploaded to google drive, for example, final edition of work completed is chicken scratch in your own notebook. The work completed by the member is completely inaccurate and must be completely reworked. Basic approach was incorrect, and not agreed upon by the team. No communication from team member about their struggles to obtain accurate work. Does not behave responsibly in situations related to project work and does not always respects all individual team members. Team member demeans other team members’ work. Team member is doing work unrelated to the goals of the collective team Team member is completely uninterested in anything related to project and becomes a burden to the productivity of the team.

Plans for next phase

Team Level Goal for Phase 2

The team’s goal for Phase 2 is the development of a functional decomposition, continued benchmarking, concept creation and selection, feasibility analysis, systems architecture, and initial design concepts. The team will also continue to monitor risks, schedule, and costs while further developing relationships with organizations for user testing and solidifying the user testing plan.

The team's individual three-week plans can be found in a compiled document here.
