There are provided a wearable robot and a method of controlling the same. The method includes obtaining a joint angle and a joint angular velocity of a plurality of joints, calculating a target joint angle of one joint among the plurality of joints using a joint angle and a joint angular velocity of at least one joint among the other joints, calculating assistive torque to be applied to the one joint using the calculated target joint angle, and outputting the calculated assistive torque to the one joint.

A system and method for transmission of a signal for a powered assistive device has a sensor node with a wireless transmitter adapted for digitally transmitting a transmitted signal, the sensor node adapted for receiving and monitoring a sensor signal from a sensor attached to a user, and a master node with a controller and a wireless receiver for receiving the transmitted signal from the wireless transmitter. The master node processes the transmitted signal and communicates a control signal to the powered assistive device. The wireless transmitter transmits the transmitted signal at a first rate when the wireless transmitter adapted to transmit the transmitted signal at a first rate when the sensor signal is indicative of the rest state and to transmit the transmitted signal at a second rate when the sensor signal is indicative of the active state, the second rate being greater than the first rate.

This document describes systems and methods for controlling an exoskeleton. The system receives a measurement of a first torque applied to a rotational joint coupling a first component to a second component, the first torque being applied by a motor via a cable. The system determines, based on the measurement of the first torque, a first portion of a second torque to apply to the rotational joint. The system determines, based on the measurement of the first torque, a second portion of the second torque to apply to the rotational joint. The system determines a value of the second torque to apply to the rotational joint based on the first portion and the second portion. The system controls the motor for applying the second torque to the rotational joint via the cable.

In at least some aspects, the present concepts include a method for configuring an assistive flexible suit including the acts of outfitting a person with an assistive flexible suit, monitoring an output of at least one sensor of the assistive flexible suit as the person moves in a first controlled movement environment, identifying at least one predefined gait event using the output of the at least one sensor, adjusting an actuation profile of the at least one actuator and continuing to perform the acts of monitoring, identifying and adjusting until an actuation profile of the at least one actuator generates a beneficial moment about the at least one joint to promote an improvement in gait. The at least one controller is then set to implement the actuation profile.

A method and apparatus for rehabilitation and training of an injured limb by using the corresponding functional healthy limb to control the motion of the injured limb are presented. A sensor system on the healthy and active limb, a processing unit, and a power supply are provided in the apparatus to provide signals that activate a powered mechanism configured for moving individual bones on the injured passive limb.

A walking training apparatus 1 includes a leg robot 2 attached to a leg of a walking trainee, a motor 261 configured to rotationally drive a knee joint 22 of the leg robot 2, a control unit 332 configured to control the motor 261 so that the motor 261 rotationally drives the knee joint 22 in a leg-idling period in a gait motion of the walking trainee, a motor torque detection unit 262 configured to detect a motor torque, the motor torque being a torque generated by the motor 261, and a determination unit 333 configured to determine whether or not the walking trainee is in a spasticity state or a rigidity state by using a value of the motor torque detected in the leg-idling period by the motor torque detection unit 262.

In one example, an apparatus includes a baseplate, a footplate connected to the baseplate, a heel support connected to the footplate, an instep securing device connected to the heel support or footplate, a calf attachment member configured to releasably attach to a leg of a user, and a first cord movably connected to the baseplate, the first cord terminating at its first end in a handle, and a second end of the first cord is configured to attach to the calf attachment member.

The invention according to the application relates to a locomotion therapy and rehabilitation device developed for patients whose locomotion function is either lost or declined due to spinal disorders, orthopaedic surgeries and central nervous system disorders to redevelop and improve their walking ability.

Hybrid terrain-adaptive lower-extremity apparatus and methods that perform in a variety of different situations by detecting the terrain that is being traversed, and adapting to the detected terrain. In some embodiments, the ability to control the apparatus for each of these situations builds upon five basic capabilities: (1) determining the activity being performed; (2) dynamically controlling the characteristics of the apparatus based on the activity that is being performed; (3) dynamically driving the apparatus based on the activity that is being performed; (4) determining terrain texture irregularities (e.g., how sticky is the terrain, how slippery is the terrain, is the terrain coarse or smooth, does the terrain have any obstructions, such as rocks) and (5) a mechanical design of the apparatus that can respond to the dynamic control and dynamic drive.

Exoskeleton technology is described herein. Such technology includes but is not limited to exoskeletons, exoskeleton controllers, methods for controlling an exoskeleton, and combinations thereof. The exoskeleton technology may facilitate, enhance, and/or supplant the natural mobility of a user via a combination of sensor elements, processing/control elements, and actuating elements. User movement may be elicited by electrical stimulation of the user's muscles, actuation of one or more mechanical components, or a combination thereof. In some embodiments, the exoskeleton technology may adjust in response to measured inputs, such as motions or electrical signals produced by a user. In this way, the exoskeleton technology may interpret known inputs and learn new inputs, which may lead to a more seamless user experience.
