Resumo

The main objective is to develop an adaptive strategy based on variable impedance for walking rehabilitation of post-stroke patients. The proposed strategy will be evaluated in two different robotic devices. The first device is the lower limb exoskeleton Exo-Kanguera, designed and built by the proposer in previous projects. The device has three degrees of freedom, acting at hip, knee, and ankle joints using series elastic actuators. The second device, named Anklebot, has active actuation in two ankle joints (dorsi/plantar flexion and inversion/version) by controlling the mechanical impedance of the interface between the device and the user. The proposed adaptive strategy considers the variation of the mechanical impedance of the robots joints based on the performance and participation of the patient during the therapy session, according to the four sub-systems: Robust Position Estimation, Impedance Control, Patient/Exoskeleton Interaction Mode, and Adaptive Impedance Strategy. The proposal is mainly related to the sub-systems Patient/Exoskeleton Interaction Model and Adaptive Impedance Strategy. (AU)
