  1. 1. Walking efficiently with smart springs

    Författare :Israel Luis; Elena Gutierrez-Farewik; Ruoli Wang; Benjamin J. Fregly; KTH; []
    Nyckelord :Musculoskeletal modeling and simulation; muscle-tendon biomechanics; muscle parameter calibration; metabolic energy models; gait analysis; exoskeleton assistance; biomechanics; Biomekanisk modellering och simulering; rörelseorganen; biomekanik; muskel; muskelmodell och muskelarkitektur; metabolisk energi och kostnad; gång; gånganalys; exoskelett; hjälpmedel; gångpatologi; Teknisk mekanik; Engineering Mechanics;

    Sammanfattning : Numerous assistive exoskeletons have been developed in recent years to assist walking in individuals with and without motor disorders. A standard metric to measure the efficacy of assistance is the change in the metabolic energy cost between unassisted and assisted conditions. LÄS MER

  2. 2. The Robustness and Energy Evaluation of a Linear Quadratic Regulator for a Rehabilitation Hip Exoskeleton

    Författare :Rabé Andersson; Niclas Björsell; Daniel Rönnow; Gianni Borghesan; Högskolan i Gävle; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hip Rehabilitation Exoskeleton; Robust Controller; Energy Consumption; Series Elastic Actuator SEA ; LQR Control; Luenberger State Observer; Torque Control; Höftexoskelett för rehabilitering; Robust reglering; Energiförbrukning; serieelastiskt manöverdon SEA ; LQR reglering; Luenberger State Obser-ver; Moment reglering;

    Sammanfattning : The implications of gait disorder, muscle weakness, and spinal cord injuries for work and age-related mobility degradation have increased the need for rehabilitation exoskeletons. Specifically, the hip rehabilitation exoskeletons due to a high percentage of the mechanical power is generated by this join during the gait cycle. LÄS MER

  3. 3. Design and Control Parameter Optimization of Soft Ankle Exoskeleton for People with Dropfoot and Excessive Inversion

    Författare :Xiaochen Zhang; Elena Gutierrez-Farewik; Ruoli Wang; Susanne Palmcrantz; Shaoping Bai; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Assistive device; Biomechanics; Gait impairment; Movement augmentation; Assistiv enhet; Biomekanik; Gångnedsättning; Rörelseförstärkning; Teknisk mekanik; Engineering Mechanics;

    Sammanfattning : Wearable robotics and exoskeletons have been explored for their efficacy in physical rehabilitation and for assistance in daily activities for people with motor disorders. The overall objective of this thesis is to design a powered soft exoskeleton for people with dropfoot and excessive inversion, commonly after a stroke, and to optimize the control parameters for each individual while considering different dimensions.
