style=\"text-align:center\"><span style=\"color:#ffffff\">Welcome to Biomechatronics System Design Lab<\/span><\/h1>\n<\/header>\n\n<section style=\"text-align:justify\">\n<p>The Biomechatronics System Design Lab at Miami University focuses on the design, modeling, control, and experimental validation of intelligent robotic systems that physically interact with the human body. Led by Dr. Sk Hasan, the lab integrates mechanical design, mechatronics, sensors, actuators, dynamic modeling, control systems, artificial intelligence, and human-centered engineering to develop assistive and rehabilitation technologies. Our work is motivated by a central goal: to create robotic systems that can support human movement, enhance rehabilitation, improve safety, and expand independence for individuals with mobility or motor-function limitations.<\/p>\n\n<p>The lab\u2019s research is positioned at the intersection of robotics, biomechanics, control engineering, instrumentation, and machine intelligence. We are especially interested in wearable robotic systems such as upper-extremity and lower-extremity exoskeleton robots, where engineering design must be closely aligned with human anatomy, comfort, safety, intention, and task performance. By combining theoretical modeling with hardware development and experimental testing, the lab seeks to translate fundamental engineering principles into practical technologies for rehabilitation, assistive motion, and human performance support.<\/p>\n<\/section>\n\n<section style=\"text-align:justify\">\n<h2 style=\"text-align:left\">Research Vision<\/h2>\n<p>Our long-term vision is to advance intelligent biomechatronic systems that can understand human movement needs and provide safe, adaptive, and personalized assistance. Traditional robotic rehabilitation systems often follow preprogrammed movements or fixed assistance patterns. In contrast, our lab investigates how robotic systems can respond to user intent, movement quality, interaction forces, physiological signals, and task performance in real time. This human-centered approach aims to make robotic assistance more natural, responsive, and effective.<\/p>\n\n<p>The lab develops technologies that bring together mechanical design, embedded sensing, dynamic simulation, adaptive control, and artificial intelligence. These technologies are intended to support future rehabilitation platforms that can assist users during repeated therapeutic movements, encourage active participation, and provide meaningful data to clinicians, researchers, and engineers.<\/p>\n<\/section>\n\n<section style=\"text-align:justify\">\n<h2 style=\"text-align:left\">Advancing Exoskeleton Robotics<\/h2>\n<p>A major research focus of the lab is the development of upper-extremity and lower-extremity exoskeleton robots for rehabilitation and assistive applications. Exoskeleton robots are wearable robotic devices that align with human joints and provide controlled support during movement. Designing such systems requires careful attention to anatomy, joint range of motion, mechanical safety, actuator selection, control stability, sensor integration, and user comfort.<\/p>\n\n<p>Our upper-extremity exoskeleton research focuses on shoulder, elbow, forearm, and wrist movement assistance. These systems are designed to support rehabilitation-relevant tasks such as reaching, lifting, positioning, forearm rotation, and wrist movement. The goal is to develop robotic platforms that can provide assist-as-needed support while encouraging voluntary user participation. This research includes mechanical design, kinematic modeling, dynamic analysis, sensor-based feedback, and adaptive controller development.<\/p>\n\n<p>Our lower-extremity exoskeleton research focuses on robotic assistance for hip, knee, and ankle motion. This work includes dynamic modeling, trajectory tracking, nonlinear control, torque estimation, and rehabilitation-oriented movement support. Together, the upper- and lower-limb exoskeleton projects provide a foundation for developing safer and more intelligent wearable robotic technologies.<\/p>\n<\/section>\n\n<section style=\"text-align:justify\">\n<h2 style=\"text-align:left\">Control Systems and Intelligent Assistance<\/h2>\n<p>Control system design is a central strength of the Biomechatronics System Design Lab. Robotic rehabilitation devices must move accurately while remaining safe during physical interaction with the user. Our lab investigates model-based control, adaptive control, robust control, computed-torque control, impedance control, and AI-assisted control methods for human-interactive robotic systems.<\/p>\n\n<p>In exoskeleton robotics, the controller must do more than track a desired trajectory. It must also respond to human effort, interaction forces, movement limitations, comfort constraints, and changing task demands. For this reason, the lab explores adaptive assistance strategies that adjust robotic behavior based on user-specific information. These approaches are intended to support safer human-robot interaction, smoother motion, improved comfort, and more personalized rehabilitation.<\/p>\n<\/section>\n\n<section style=\"text-align:justify\">\n<h2 style=\"text-align:left\">Artificial Intelligence, Sensing, and Human-State Estimation<\/h2>\n<p>The lab is actively exploring the use of artificial intelligence and multimodal sensing to improve robotic assistance. Human movement is complex and cannot be fully understood from joint angles alone. Therefore, our research considers multiple sources of information, including kinematics, interaction forces, electromyography, pressure or cuff-load sensing, visual feedback, task performance, and user engagement indicators.<\/p>\n\n<p>By combining these data streams, intelligent robotic systems may be able to estimate user intent, detect unsafe interaction, evaluate movement quality, identify fatigue-related changes, and adapt assistance levels. This research direction supports the development of robotic systems that are not only mechanically capable but also context-aware and human-responsive.<\/p>\n<\/section>\n\n<section style=\"text-align:justify\">\n<h2 style=\"text-align:left\">Instrumentation, Sensors, and Experimental Validation<\/h2>\n<p>Instrumentation is essential for understanding the performance and safety of biomechatronic systems. The lab uses sensors, data acquisition systems, embedded platforms, and real-time measurement tools to evaluate robotic motion, user interaction, and system behavior. Sensor data are used to validate mechanical design, improve controller performance, and support quantitative assessment of rehabilitation-relevant tasks.<\/p>\n\n<p>Our experimental work emphasizes measurable outcomes such as tracking accuracy, motion smoothness, interaction force, actuator performance, response time, comfort-related indicators, and repeatability. These measurements help bridge the gap between conceptual robotic design and practical, testable rehabilitation technology.<\/p>\n<\/section>\n\n<section style=\"text-align:justify\">\n<h2 style=\"text-align:left\">Innovation Through Research and Collaboration<\/h2>\n<p>The Biomechatronics System Design Lab values interdisciplinary collaboration. Our research connects mechanical engineering, electrical and computer engineering, robotics, rehabilitation science, computer science, artificial intelligence, and human factors. We aim to work with clinicians, therapists, researchers, students, industry partners, and community stakeholders to identify real needs and develop engineering solutions that are useful beyond the laboratory.<\/p>\n\n<p>Collaboration is especially important in rehabilitation robotics because successful technologies must be technically sound, clinically relevant, safe for users, and practical for real-world environments. Through collaborative research, student projects, outreach activities, and translational partnerships, the lab seeks to contribute to the next generation of assistive and rehabilitation technologies.<\/p>\n<\/section>\n\n<section style=\"text-align:justify\">\n<h2 style=\"text-align:left\">Educating the Next Generation<\/h2>\n<p>Education and student mentoring are core missions of the lab. Dr. Sk Hasan is committed to training students in robotics, control systems, mechatronics, instrumentation, modeling, simulation, and experimental research. Students working in the lab gain hands-on experience with mechanical design, sensors, actuators, programming, data analysis, control implementation, and robotic system testing.<\/p>\n\n<p>The lab provides opportunities for undergraduate and graduate students to participate in research projects, independent studies, capstone design activities, conference presentations, journal publications, and outreach demonstrations. Through these activities, students develop both technical expertise and broader professional skills such as teamwork, communication, problem solving, and research ethics.<\/p>\n<\/section>\n\n<section style=\"text-align:justify\">\n<h2 style=\"text-align:left\">Broader Impact<\/h2>\n<p>The technologies developed in the Biomechatronics System Design Lab have potential impact in rehabilitation, assistive robotics, aging support, human performance, education, and advanced manufacturing. Robotic systems that can safely assist human movement may help address challenges related to stroke rehabilitation, neuromuscular impairment, mobility limitations, repetitive therapy, therapist workload, and access to guided movement training.<\/p>\n\n<p>Beyond healthcare and rehabilitation, the lab\u2019s research contributes to fundamental knowledge in human-robot interaction, wearable robotics, dynamic system control, sensor-based adaptation, and intelligent mechatronic design. The lab also seeks to broaden participation in engineering by engaging students from diverse backgrounds and creating accessible pathways into robotics and control research.<\/p>\n<\/section>\n\n<section style=\"text-align:justify\">\n<h2 style=\"text-align:left\">Join Us in Shaping the Future<\/h2>\n<p>We invite students, researchers, clinicians, industry partners, and community members to explore our work and connect with the Biomechatronics System Design Lab. Together, we can advance human-centered robotic systems that improve movement assistance, rehabilitation technology, and quality of life. Through innovation, collaboration, and education, the lab is working to shape the future of intelligent biomechatronics\u2014one design, one experiment, and one discovery at a time.<\/p>\n<\/section>\n\n\n\n<\/div>\n\n<\/div>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Human Upper-Extremity Rehabilitation Exoskeleton Robot Human-Centered Upper-Limb Exoskeleton Design for Rehabilitation and Assistance Human Lower-Extremity Rehabilitation Exoskeleton Robot Welcome to Biomechatronics System Design Lab The [&hellip;]<\/p>\n","protected":false},"author":4908,"featured_media":0,"parent":0,"menu_order":0,"comment_status":"closed","ping_status":"closed","template":"page-templates\/full-width.php","meta":{"_bbp_topic_count":0,"_bbp_reply_count":0,"_bbp_total_topic_count":0,"_bbp_total_reply_count":0,"_bbp_voice_count":0,"_bbp_anonymous_reply_count":0,"_bbp_topic_count_hidden":0,"_bbp_reply_count_hidden":0,"_bbp_forum_subforum_count":0,"footnotes":""},"class_list":["post-97","page","type-page","status-publish","hentry"],"_links":{"self":[{"href":"https:\/\/sites.miamioh.edu\/biomechatronics-system-design-laboratory\/wp-json\/wp\/v2\/pages\/97","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/sites.miamioh.edu\/biomechatronics-system-design-laboratory\/wp-json\/wp\/v2\/pages"}],"about":[{"href":"https:\/\/sites.miamioh.edu\/biomechatronics-system-design-laboratory\/wp-json\/wp\/v2\/types\/page"}],"author":[{"embeddable":true,"href":"https:\/\/sites.miamioh.edu\/biomechatronics-system-design-laboratory\/wp-json\/wp\/v2\/users\/4908"}],"replies":[{"embeddable":true,"href":"https:\/\/sites.miamioh.edu\/biomechatronics-system-design-laboratory\/wp-json\/wp\/v2\/comments?post=97"}],"version-history":[{"count":10,"href":"https:\/\/sites.miamioh.edu\/biomechatronics-system-design-laboratory\/wp-json\/wp\/v2\/pages\/97\/revisions"}],"predecessor-version":[{"id":996,"href":"https:\/\/sites.miamioh.edu\/biomechatronics-system-design-laboratory\/wp-json\/wp\/v2\/pages\/97\/revisions\/996"}],"wp:attachment":[{"href":"https:\/\/sites.miamioh.edu\/biomechatronics-system-design-laboratory\/wp-json\/wp\/v2\/media?parent=97"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
