About

Young Sang Choi’s research centers on assistive robotics, human-robot interaction, and autonomous mobile manipulation, with a focus on improving the quality of life for individuals with severe motor impairments, particularly those with amyotrophic lateral sclerosis (ALS). His major contributions include the development of El-E, a prototype assistive robot capable of autonomously retrieving and delivering everyday objects to users with limited mobility. Choi pioneered user-centered design by conducting in-depth interviews and studies with ALS patients to prioritize a list of household objects for robotic retrieval—work that has garnered over 60 citations. His studies on object delivery methods, such as handing over versus setting down objects, have shaped how service robots interact with motor-impaired users, earning over 45 citations. Notably, his 2009 paper on household object prioritization remains a foundational reference in assistive robotics. Choi’s human-robot interaction research, including his thesis work, has been instrumental in bridging the gap between robotic capabilities and real-world user needs, making him a key figure in the field of assistive technology.
