Introduction
In recent years, advancements in robotic assistive technology have shown great promise in enhancing the quality of life for older adults with disabilities. One such innovation is the development of a robotic shower system designed to help these individuals take showers with greater ease and independence. This case study explores the role of Boyce Human Performance in the design of this groundbreaking technology, in collaboration with the University of Illinois, Urbana-Champaign, under the leadership of Dr. Wendy Rogers.

Background
Boyce Human Performance is a renowned organization specializing in Human Factors and Ergonomics, areas crucial to the successful design and implementation of assistive technologies. When Dr. Wendy Rogers, a prominent researcher at the University of Illinois, Urbana-Champaign, initiated a project to develop a robotic shower system for older adults with disabilities, Boyce Human Performance was brought on board to provide expert insights and guidance.

Project Goals
The primary objective of the project was to develop a robotic shower system that could offer varying levels of assistance to users, ranging from fully automated to fully manual modes. This flexibility would allow users to choose the level of assistance they needed, thereby promoting autonomy and comfort. Additionally, the system was designed to include a semi-autonomous option, where users could receive assistance on specific areas of the body while retaining control over other aspects of the showering process.

The Role of Boyce Human Performance
Boyce Human Performance played a pivotal role in ensuring that the design of the robotic shower system was user-centric and ergonomically sound. Michael, an expert in Human Factors and Ergonomics, was brought in to provide valuable insights and assist the development teams. His contributions focused on several key areas:

User-Centered Design
Michael emphasized the importance of understanding the specific needs, preferences, and limitations of older adults with disabilities. He conducted extensive user research, including interviews and usability tests, to gather data on how users interacted with existing shower systems and what improvements they desired.

Ergonomics
Ensuring the comfort and safety of users was paramount. Michael’s expertise in ergonomics helped the team design a system that was easy to use, reducing the physical strain on users and minimizing the risk of accidents. This included considerations such as the height and reach of the robotic arm and the placement of controls.

Intelligent Arm Design
A key feature of the robotic shower system is its intelligent arm, which drops down from the ceiling. Michael provided insights into the design and functionality of this arm, ensuring it could move smoothly and accurately to assist users in various showering tasks. The arm’s movements were carefully calibrated to be gentle and precise, accommodating the diverse needs of users.

Development of the Prototype
At this stage of the project, the primary goal is to develop a prototype that can be used for user testing. Boyce Human Performance is working closely with Dr. Wendy Rogers and her team to create a functional prototype that incorporates all the design elements and features discussed. This prototype will undergo rigorous testing with actual users to gather feedback and make necessary refinements.

Challenges and Solutions
While the development of the robotic shower system has shown great promise, there are several challenges that the team is currently navigating. One of the most significant challenges is the affordability of the device, including the costs associated with maintenance and installation. The team is exploring various solutions to address this issue:

Cost Reduction
Efforts are being made to identify cost-effective materials and manufacturing processes that do not compromise the quality and functionality of the device. The team is also exploring potential partnerships with suppliers and manufacturers to reduce production costs.

Funding and Grants
Securing funding and grants from government agencies, non-profit organizations, and private investors is another avenue being pursued. These funds could help subsidize the cost of the devices for users, making them more accessible to a broader population.

Insurance Coverage
Advocacy for insurance coverage of the robotic shower system is ongoing. By working with healthcare providers and insurance companies, the team hopes to have the device recognized as a necessary medical aid, thereby reducing the out-of-pocket expenses for users.

Maintenance and Support
To address concerns about maintenance, the team is developing a comprehensive support plan. This includes training for caregivers and family members, as well as the establishment of service centers that can provide timely repairs and maintenance.

Conclusion
The collaboration between Boyce Human Performance and the University of Illinois, Urbana-Champaign, under the guidance of Dr. Wendy Rogers, represents a significant step forward in the field of robotic assistive technology. The development of the robotic shower system has the potential to greatly improve the quality of life for older adults with disabilities, offering them greater independence and dignity in their daily lives. While challenges remain, the dedication and expertise of the team provide a strong foundation for overcoming these obstacles and achieving the project’s goals.
