This technology features an exoskeleton robot that detects gait intention by placing pads on the front and back of the wearer's thighs, linked together to pivot around a central point. The displacement of the pads during leg movement triggers contact and pressure changes in the sensors, allowing the system to interpret the user's intent.
Conventional methods, such as electromyography (EMG) sensors, require attachment to deep muscle tissue, leading to complex structures and high costs. Furthermore, sensors attached to flexible straps often shift during movement, resulting in poor accuracy for gait intention detection.
This technology uses a mechanical approach to detect gait intention by securing a connecting link to the thigh support and designing the protrusions on the front and rear push pads to selectively press against pressure sensors. Applicable to gait rehabilitation and industrial strength assistance, it provides a low-cost, reliable solution for intention recognition without the need for biosignal sensors.
