Design and Evaluation of a Pediatric Lower-Limb Exoskeleton Joint Actuator

Abstract: Lower-limb exoskeletons have undergone significant developments for aiding in the ambulation of adults with gait impairment. However, advancements in exoskeletons for the pediatric population have comparatively been lacking. This paper presents a newly developed joint actuator designed to drive the hip and knee joints of a pediatric lower-limb exoskeleton. The performance requirements associated with the actuators were determined based on a target audience of children ages 6–11 years old. The developed actuato… Show more

“…Passive resistance was determined as the torque required to move the actuator at a given speed without the presence of an external load. The procedure followed here was similar to what has been done by others when evaluating actuators [25]. Prior work has established that passive resistance for these types of devices is predominantly a function of joint speed [37,38].…”

“…Hence, they provide input data required for an actuator design. The authors in [106] stressed that the advantages electric actuators offer are preferential, in contrast to their hydraulic and pneumatic actuated counterparts, which are bulky in size. According to them, it is impractical to have each modular exoskeleton part designed with independent power units.…”

“…Research issues concerning the protection of the driver and passengers of passenger vehicles against the consequences of any road collisions belong to the issues of impact biomechanics. An important element is the choice of the method used as well as the criteria for assessing the risk of sustaining an injury [8,9]. It should be noted that the result of the complicated nature of the loads acting on the driver or passenger during a collision is the main reason for the model testing of the applied vehicle passive safety systems.…”
