This technology assists pelvic movement using three variable-length modules (center, left, and right) that connect a wearable harness to its supporting frame. Sensors detect the user's gait intention, and the length of each module is independently controlled to assist with pelvic movement in the sagittal and transverse planes.
Existing lower-limb exoskeleton robots are prone to falling during gait due to the instability of their mechanical structures and control algorithms, which are typically based on bipedal or quadrupedal locomotion. For paralyzed patients with insufficient muscle strength, a fall can pose a significant risk of serious injury.
This technology features variable-length modules pivotally coupled to the rear, left, and right sides of a harness, with a control unit that identifies gait intentions (forward movement, rotation) based on sensor data. By driving motor cylinders and rods to push or pull the harness, the system actively assists with the forward, backward, and rotational movements of the pelvis according to the user's gait intention, applying weighted control. Applicable to rehabilitation training, gait assistance, and medical/welfare services, it enhances gait stability for paralyzed patients by supporting pelvic movement in the sagittal and transverse planes.
