ABSTRACT
The broader impact/commercial potential of this Phase I project is its innovative and potentially transformative contribution to assistive technologies for infants with motor impairment. In the United States, over 40,000 infants per year are born with conditions, such as cerebral palsy, spina bifida, and Down syndrome, that often result in motor impairment. There is currently no device that provides independent movement to infants with motor limitations. Since children learn a great deal about their physical and social environments when they begin to crawl/walk, conditions that deny or delay independent movement can impact cognitive, language, and social development. A device that will let these infants move and explore at the same age as other children could mitigate these developmental delays and facilitate full integration into society. Lifetime cost of healthcare for these children has been estimated at $250,000. Providing early independent movement could result in a potential $50,000 lifetime reduction in additional interventions such, as behavioral and occupational therapy, special education, and the need for healthcare and educational aides. This amounts to over $200,000,000 in savings per year to the health and education systems.
This Small Business Innovation Research (SBIR) Phase I project addresses the need, expressed by parents and therapists, for a device that will allow infants with motor impairment to move independently at the same age as their typically developing peers. Currently, no such device is available. The intellectual merit of the proposed work is the development of a novel control method for a powered device that can be used by infants as young as 6 months old: The device moves in the direction that the infant leans (as when reaching toward a toy or parent) while preventing collisions and falls. Previous research has shown that infants as young as five months old can learn to use this control method to purposefully steer a powered device in all directions. The research objectives of this project are to build and validate a second-generation prototype that can be used by parents and clinicians outside of a research setting. Successful completion of these objectives will advance the device from a research testbed to a viable, if limited, prototype, enabling future work to evaluate the impact of the device on the development of cognitive, social, and communication skills for infants with disabilities.
This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
PROJECT OUTCOMES REPORT

This SBIR Phase I project was focused on developing a viable prototype of the WeeBot, a powered device designed for young children with mobility impairment or delay to allow them to explore and interact with their surroundings. There are currently few options on the market for children with mobility impairment, and none for those at the age when critical exploration typically begins (6-12 months of age). Most available options are too cognitively demanding for younger children and are focused on movement alone, rather than environmental exploration. The WeeBot addresses the latter, currently unaddressed need: It is hands-free and has a unique control method that can be easily learned by very young children and used to readily interact with objects and people.
In this Phase I research, we focused on making significant improvements to our research WeeBot device to advance it toward commercial viability. We developed a fully integrated device and added additional safety measures, such as non-contact sensors to slow down the WeeBot as the child approaches an object, a bumper that stops the WeeBot on contact, a remote control to allow an adult to take control of the WeeBot if needed, and an emergency stop button that cuts all power to the WeeBot.
We also demonstrated the efficacy of our product through a small human subjects study performed by clinicians in the Occupational Therapy department at Quinnipiac University. Ages for the infants tested ranged from 6 mos to 20 mos of age. Of the five children who finished the testing, 3 of the 5 were able to learn to successfully control the robot in all directions and displayed unprompted goal-directed movement of the WeeBot. On the ALP (Assessment of Learning Powered mobility use) scores ranged from 1 (novice) to 7 (proficient.) Feedback from the clinicians was positive, and they provided extensive input and suggestions for future improvement to the device that we intend to incorporate into our next design round.
