We rely on horizontal surfaces such as desks, cabinets and shelves for storing and organizing our belongings. Maintaining an organized lifestyle is an important daily routine that reduces the negative mental and physical effects caused by cluttering. When poorly managed, domestic items can be difficult to find, causing frustration and cluttering which negatively impact our physical and mental wellness. Manifestations of this negative impact include a reduction in working memory, an increase in stress, and difficulty in object identification.

A messy environment can be especially challenging for people with various forms of impairment, including older adults with mild cognitive impairment, patients recovering at home needing medication management, high-functioning individuals on the autism spectrum, and people of all ages that have mobility challenges due to an accident or otherwise.

SORT (“Stuff-Organizing Robot Team”) is a system of wall-climbing robots for supporting independent living by helping users organize domestic items along vertical surfaces. SORT suggests how assistive technologies leverage our everyday physical environments to perform functional tasks towards improving users’ overall wellness. SORT is part of an emerging trend, advanced by the Architectural Robotics Lab, of research in tangible and embedded interaction within homes, workplaces, classrooms, and healthcare facilities.
