Abstract: The Active Knee Rehabilitation Orthotic System (ANdROS) is a wearable and portable assistive tool for gait rehabilitation and monitoring of people with motor control deficits due to a neurological ailment, such as stroke. ANdROS reinforces a desired gait pattern by continually applying a corrective torque around the knee joint, commanded by a impedance controller. A sensorized yet unactuated brace worn on the unimpaired leg is used to synchronize the playback of the desired trajectory based on the user's intent. The device is mechanically grounded through two ankle foot orthoses (AFOs) rigidly attached to the main structure, which helps reduce the weight perceived by the user.

Abstract: A balanced planetary gearbox including an assembly having an input stage and an output stage. The assembly includes two grounds, each with ground rollers and ground rings. The two grounds are fixedly attached to one another. The assembly includes a sun gear and planet sub-assemblies between the two grounds. The planet sub-assemblies include at least one input planet gear and one output planet gear. The sun gear and the input planet gears include rollers. An abutment of rollers in the gearbox keeps the sun gear and the planet gears in alignment. The output gear meshes with an output ring disposed in between the two ground rings, such that a combination of the at least one input planet gears from each of the plurality of planet sub-assemblies provides a structural symmetry to the planetary gearbox.
