SINGLE-LOWER-LIMB REHABILITATION EXOSKELETON APPARATUS AND CONTROL METHOD
20230210707 · 2023-07-06 ·

A single-lower-limb rehabilitation exoskeleton apparatus and control methods includes a controller, an intact lower-limb component and a paretic lower-limb component connecting communicatively with the controller. The controller is used to determine the current state of the intact lower-limb through the intact lower-limb component and the current state of the paretic lower-limb through the paretic lower-limb component. When the intact lower-limb component is in the lifting state, the movement data of the intact lower-limb is collected and sent to the controller. The controller is used to determine the corresponding gait data for the paretic lower-limb component according to the movement data of the intact lower-limb and send the gait data to the paretic lower-limb component. The paretic lower-limb component is used to drive the paretic lower-limb to move or walk according to the gait data while the intact lower-limb is in the supporting state.

The load calculation unit calculates a total load value, based on the sensor output information and geometric information of a load region specified based on the sensor output information, the geometric information including at least a perimeter of the load region in a horizontal direction. The output unit outputs the total load value.

WALKING TRAINING SYSTEM, CONTROL METHOD, AND PROGRAM

A walking training system includes: a tension unit that pulls a leg of a trainee upward and forward; a sensor provided for determining a start timing of a swinging end phase of the leg; and a control unit that reduces a tensile force of the tension unit from the start timing of the swinging end phase.

SYSTEM FOR GUIDING MOTIONS OF A TARGET JOINT

Examples of a motion guiding device of a target joint of a target body are disclosed. The device allows three degree-of-freedom (DOF) motion about a remote center of rotation that is approximately aligned to a center of rotation of the target joint. The device comprises a base adjustably connected to the target body and three rotary joints interconnected with a network of linkages. One end of the network of linkages is connected to the base and the opposite end to an effector plate. At least one of the three rotary joints is not aligned with an axes of motion of the target joint and any of these rotary joints may be positioned under angle with respect to the others. Each of the rotary joints provides one DOF of rotary motion about the respective axes and each axis of the three rotary joints intersect at the remote center of rotation. The geometry of the network of linkages is adjustable to adjust a position of the remote center of rotation in three dimensions. The three rotary joints and the network of linkages rotate the effector plate about the remote center of rotation that is approximately align with the center of rotation of the target joint. This system may be connected with one or more parallel branches for additional actuation.
