To date, hip exoskeletons have enhanced user mobility during controlled in-lab settings; however, the lack of an exoskeleton controller able to autonomously adapt with changes in user, activity, and activity intensity limits the viability of these systems in daily life. In this proposal, a novel hip exoskeleton controller is introduced, which commands assistance based on instantaneous estimates of the user\u0026rsquo;s hip flexion\/extension moment via a temporal convolutional network. By modulating exoskeleton assistance based on hip moments, the controller uses a single, continuous variable to account for changes in user, activity, and intensity, removing the limitations of previous exoskeleton controllers. To maximize the performance and generalizability of the hip moment estimator, the model structure (Aim 1) and training set activities (Aim 3) will be optimized. To study human response to this framework, user metabolic cost during multimodal ambulation (Aim 2) and lower-limb muscle effort during an expanded activity set, including lunging and squatting, (Aim 3) will be quantified. Thus, this proposal introduces a first-of-its-kind exoskeleton controller that autonomously customizes assistance regardless of activity, bridging the gap between in-lab and real-world settings.\u003C\/p\u003E\r\n\r\n\u003Cp\u003E\u0026nbsp;\u003C\/p\u003E\r\n","summary":null,"format":"limited_html"}],"field_subtitle":"","field_summary":"","field_summary_sentence":[{"value":"A Framework for Autonomous Exoskeleton Assistance Independent of Activity"}],"uid":"27707","created_gmt":"2021-12-16 17:32:26","changed_gmt":"2021-12-16 17:32:26","author":"Tatianna Richardson","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2021-12-13T10:00:00-05:00","event_time_end":"2021-12-13T12:00:00-05:00","event_time_end_last":"2021-12-13T12:00:00-05:00","gmt_time_start":"2021-12-13 15:00:00","gmt_time_end":"2021-12-13 17:00:00","gmt_time_end_last":"2021-12-13 17:00:00","rrule":null,"timezone":"America\/New_York"},"extras":[],"groups":[{"id":"221981","name":"Graduate Studies"}],"categories":[],"keywords":[{"id":"102851","name":"Phd proposal"}],"core_research_areas":[],"news_room_topics":[],"event_categories":[{"id":"1788","name":"Other\/Miscellaneous"}],"invited_audience":[{"id":"78761","name":"Faculty\/Staff"},{"id":"78771","name":"Public"},{"id":"78751","name":"Undergraduate students"}],"affiliations":[],"classification":[],"areas_of_expertise":[],"news_and_recent_appearances":[],"phone":[],"contact":[],"email":[],"slides":[],"orientation":[],"userdata":""}}}
