Embodiments herein are directed to a system that includes a powered wheelchair, a user-worn exoskeleton, and a master controller. The master controller monitors the independent movements of the powered wheelchair and the user-worn exoskeleton. The master controller prioritizes the movement of the powered wheelchair and the user-worn exoskeleton such that only one of the powered wheelchair or the user-worn exoskeleton will have the priority to complete the intended movement. The master controller may coordinate movements between the powered wheelchair and the user-worn exoskeleton so to perform a plurality of predetermined programs. For example, assisting a user to sit within the powered wheelchair, to assist a user to stand from a seating position when outside of the powered wheelchair, and/or use the powered wheelchair as a guide for walking.

A robotic assistant includes a wheeled base, a body positioned on the base, a foldable seat rotatably connected to the body, an actuator to rotate the foldable seat with respect to the body, and a control system that receives command instructions. The actuator is electrically coupled to the control system. In response to the command instructions, the control system is to control the actuator to rotate the foldable seat to a folded position or an unfolded position. The control system is further to detect whether an external force from a user has applied to the foldable seat, and release the actuator to allow the foldable seat to be manually rotated.

A mobile robot system and method for determining the stiffness of a human arm while moving with a user during overground interaction as the user holds the robot's handle and exchanges forces with it. A mobile base moves with the user, a robot arm interacts with the user, and a controller determines the stiffness. The robot arm includes servomotors driving a linkage mechanism, an end effector including the handle supported by the linkage mechanism, and a force transducer measuring a force applied by the user to the handle. The controller causes the robot arm to generate a force perturbation at the handle, measure a peak velocity achieved by the human arm, determine the stiffness of the human arm as a function of force and displacement, and control operation of the system based on the determined stiffness. A robot body may allow for adjusting the height of the robot arm.

A walker is provided. The walker includes a walker body, a handle unit, a first wheel unit and a second wheel unit. The handle unit is connected to the walker body. The first wheel unit is connected to the walker body. The second wheel unit is connected to the walker body. In an auxiliary mode, a first gap is formed between the first wheel unit and the second wheel unit. In a driving mode, a second gap is formed between the first wheel unit and the second wheel unit. The first gap is smaller than the second gap.

A intelligent rollator has a vehicle body, a seat provided in the vehicle body for a person to sit or place items on, and front and rear wheels provided at the bottom of the wheels, driven by motors. A power-assist control method includes the following steps: obtaining the load weight of the vehicle body; and entering a first power-assist compensation mode to compensate the torque output of the motor according to a first power-assist compensation threshold, when the load weight is greater than a set threshold. The first power-assist compensation threshold is direct proportional to at least one of the following parameters: the load weight of the intelligent rollator, and the moving speed of the intelligent rollator. The intelligent rollator can be used safely even under the situations of huge different loads, as with load or not the motor torque output is prevented from being too large to drag the user to fall down, or when the user is seated the motor torque output is prevented from being too small and power is insufficient.

A gait rehabilitation device includes a stand equipped with casters spaced apart along the width and the length of the stand. Two movable arms forming a pedal crank, each arm comprising a first end rotatably mounted on the device about an axis parallel to the width of the stand. The wedging element to wedge the patient’s foot/leg is adjustable and lockable according to the width of the device. The thigh/leg spreader to adjustably space the patient’s thighs/legs on either side of the saddle support is configured to follow the alternating movement of the patient’s lower limbs. The position setting of the wedging element according to the width of the device is independent of the space setting of the thigh/leg spreader.

A suspension system (2) for assisting a user (4) to navigate a staircase (6), the suspension system comprising: a beam (8) positioned above the staircase (6); a carriage (18) displaceable along said beam (8) between a first position at the bottom of the staircase (6) and a second position at the top of the staircase (6); a harness (14) securable to the user (4), said harness (14) being operably connectable to said carriage (18) such that said carriage (18) follows the user (4) as the user (4) navigates the staircase (6); and a brake (42) operably connected to said carriage (18) for braking said carriage; wherein if the user (4) falls while navigating the staircase (6), said brake (42) stops said carriage (18) in place and the user (4) is suspended above the staircase.

A bodyweight unloading locomotive device includes a frame configured to support locomotive movement, and an unloading assembly carried by the frame. The unloading assembly includes a spring having a fixed end coupled to the frame and an opposed free end, a cam assembly mounted to the frame for rotational movement, a first tether extending from the free end of the spring to the cam assembly, and a second tether extending from the cam assembly to a load. The unloading assembly exerts an unloading force on the load with respect to the frame.

A mobility device positionable between a powered transport position and a powered wheelchair position is provided. The mobility device includes a frame including a pair of side rails, a pair of wheels on each side rail, a distance between each wheel on a corresponding side rail defining a length of the mobility device, a pair of arms coupled to an end of the pair of side rails, and a seat member positioned between the pair of arms. A pair of foot plates is pivotally attached to the pair of side rails and rotatable between an unfolded position in which the foot plate is horizontal and a folded position in which the foot plate is vertical. Each foot plate having a length at least substantially equal to the length of the mobility device.
